There are a set of available properties to all Maven projects.

From [Introduction to the POM](https://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Available_Variables):
&gt;`project.basedir`: The directory that the current project resides in.

This means this points to where your Maven projects resides on your system. It corresponds to the location of the `pom.xml` file. If your POM is located inside `/path/to/project/pom.xml` then this property will evaluate to `/path/to/project`.

Some properties are also inherited from the [Super POM](https://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Super_POM), which is the case for `project.build.directory`. It is the value inside the `&lt;project&gt;&lt;build&gt;&lt;directory&gt;` element of the POM. You can get a description of all those values by looking at the [Maven model](https://maven.apache.org/ref/3.3.9/maven-model/maven.html#class_build). For `project.build.directory`, it is:
&gt; The directory where all files generated by the build are placed. The default value is `target`. 

This is the directory that will hold every generated file by the build.

`${project.basedir}` is the root directory of your project. 

`${project.build.directory}` is equivalent to `${project.basedir}/target`

as it is defined here: 
https://github.com/apache/maven/blob/trunk/maven-model-builder/src/main/resources/org/apache/maven/model/pom-4.0.0.xml#L53

Say I have a list of items, and I want to iterate over the first few of it:

    items = list(range(10)) # I mean this to represent any kind of iterable.
    limit = 5

## Naive implementation

The Python na&#239;f coming from other languages would probably write this perfectly serviceable and performant (if unidiomatic) code:

    index = 0
    for item in items: # Python&#39;s `for` loop is a for-each.
        print(item)    # or whatever function of that item.
        index += 1
        if index == limit:
            break

## More idiomatic implementation

But Python has enumerate, which subsumes about half of that code nicely:

    for index, item in enumerate(items):
        print(item)
        if index == limit: # There&#39;s gotta be a better way.
            break

So we&#39;ve about cut the extra code in half. But there&#39;s gotta be a better way.

# Can we approximate the below pseudocode behavior?

If enumerate took another optional `stop` argument (for example, it takes a `start` argument like this: `enumerate(items, start=1)`) that would, I think, be ideal, but the below doesn&#39;t exist (see the [documentation on enumerate here][1]):

    # hypothetical code, not implemented:
    for _, item in enumerate(items, start=0, stop=limit): # `stop` not implemented
        print(item)

Note that there would be no need to name the `index` because there is no need to reference it.

Is there an idiomatic way to write the above? How?

A secondary question: why isn&#39;t this built into enumerate?

I am currently trying to recursively delete a directory... Strangely enough the shortest piece of code I was able to find is the following construct, employing an *ad-hoc inner class* and in a *visitor pattern*...


	Path rootPath = Paths.get(&quot;data/to-delete&quot;);

	try {
	  Files.walkFileTree(rootPath, new SimpleFileVisitor&lt;Path&gt;() {
		@Override
		public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException {
		  System.out.println(&quot;delete file: &quot; + file.toString());
		  Files.delete(file);
		  return FileVisitResult.CONTINUE;
		}

		@Override
		public FileVisitResult postVisitDirectory(Path dir, IOException exc) throws IOException {
		  Files.delete(dir);
		  System.out.println(&quot;delete dir: &quot; + dir.toString());
		  return FileVisitResult.CONTINUE;
		}
	  });
	} catch(IOException e){
	  e.printStackTrace();
	}

Source: [here][1]

This feels horribly clumsy and verbose, given that the new `nio` APIs remove so much clutter and boilerplate...

**Is there any shorter way of achieving a forced, recursive directory delete?**

I&#39;m looking for pure native Java 1.8 methods, so please don&#39;t link to external libraries...

I&#39;ve been reading in other post that try to compile with Java 8 might cause that error but not my case, I have the following Java version:

    java version &quot;1.7.0_79&quot;
    OpenJDK Runtime Environment (IcedTea 2.5.5) (7u79-2.5.5-0ubuntu0.14.04.2)
    OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

OS: Linux Mint
(I&#39;m not have Java 8 installed.)
Build: MAVEN

Can anyone help me with this?


Unsupported major.minor version 52.0 in my app

Since I&#39;ve updated my version of intelliJ (14.x to 15.x) it has started automatically collapsing single line methods in the `Java` editor:

Previous version:

    public void setContext(SecurityContext context) {
        this.context = context;
    }

Latest version:

    public void setContext(SecurityContext context) { this.context = context; }

Is there a way to prevent this?  I find the original version much easier on the eyes!

Thanks.

I am trying to pass path param and query params in a URL but I am getting a weird error. below is the code

    

        String url = &quot;http://test.com/Services/rest/{id}/Identifier&quot;
        Map&lt;String, String&gt; params = new HashMap&lt;String, String&gt;();
        params.put(&quot;id&quot;, &quot;1234&quot;);
        UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(url)
        									.queryParam(&quot;name&quot;, &quot;myName&quot;);
        String uriBuilder = builder.build().encode().toUriString();
        restTemplate.exchange(uriBuilder , HttpMethod.PUT, requestEntity,
    					class_p, params);

and my url is becoming `http://test.com/Services/rest/%7Bid%7D/Identifier?name=myName`

what should I do to make it work. I am expecting `http://test.com/Services/rest/{id}/Identifier?name=myName` so that params will add id to the url

please suggest. thanks in Advance

RestTemplate: How to send URL and query parameters together

As I am trying this with spring boot and webservices with postman chrome add-ons.

In postman `content-type=&quot;multipart/form-data&quot;` and I am getting the below exception.

    HTTP Status 500 - Request processing failed; 
    nested exception is org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; 
    nested exception is java.io.IOException: 
    org.apache.tomcat.util.http.fileupload.FileUploadException: the request was rejected because no multipart boundary was found

In Controller I specified the below code

    @ResponseBody
	@RequestMapping(value = &quot;/file&quot;, headers = &quot;Content-Type= multipart/form-data&quot;, method = RequestMethod.POST)

	public String upload(@RequestParam(&quot;name&quot;) String name,
			@RequestParam(value = &quot;file&quot;, required = true) MultipartFile file)
	//@RequestParam ()CommonsMultipartFile[] fileUpload
	{
		// @RequestMapping(value=&quot;/newDocument&quot;, , method = RequestMethod.POST)
		if (!file.isEmpty()) {
			try {
				byte[] fileContent = file.getBytes();
				fileSystemHandler.create(123, fileContent, name);
				return &quot;You successfully uploaded &quot; + name + &quot;!&quot;;
			} catch (Exception e) {
				return &quot;You failed to upload &quot; + name + &quot; =&gt; &quot; + e.getMessage();
			}
		} else {
			return &quot;You failed to upload &quot; + name + &quot; because the file was empty.&quot;;
		}
	}


Here I specify the file handler code

    public String create(int jonId, byte[] fileContent, String name) {
		String status = &quot;Created file...&quot;;
		try {
			String path = env.getProperty(&quot;file.uploadPath&quot;) + name;
			File newFile = new File(path);
			newFile.createNewFile();
			BufferedOutputStream stream = new BufferedOutputStream(new FileOutputStream(newFile));
			stream.write(fileContent);
			stream.close();
		} catch (IOException ex) {
			status = &quot;Failed to create file...&quot;;
			Logger.getLogger(FileSystemHandler.class.getName()).log(Level.SEVERE, null, ex);
		}
		return status;
	}

Could not autowire field:RestTemplate in Spring boot application

Usually I&#39;m running my Spring Boot application with command:

    mvn spring-boot:run -Drun.arguments=--server.port=9090 \
       -Dpath.to.config.dir=/var/data/my/config/dir

I want to set custom port to debug, so I can connect from eclipse. When I add arguments from example https://docs.spring.io/spring-boot/docs/1.1.2.RELEASE/maven-plugin/examples/run-debug.html

    mvn spring-boot:run -Drun.arguments=--server.port=9090 \
       -Dpath.to.config.dir=/var/data/my/config/dir \
       -Drun.jvmArguments=&quot;-Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8787&quot;

it works but other arguments like `server.port` or `path.to.config.dir` are no longer recognized and I get exception like:

    org.springframework.beans.factory.BeanDefinitionStoreException: Failed
    to parse configuration class [com.my.app.Controller]; nested exception
    is java.lang.IllegalArgumentException: Could not resolve placeholder
    &#39;path.to.config.dir&#39; in string value

In a maven project I trying to replace some tokens using maven resource filtering but it does not work. I have some other projects which works but does not work in this single project not sure what is wrong.

I tried different maven commands as below but does not work.

**Update:-**

I figured out this problem is caused due to the spring boot dependency.
If I comment the `&lt;parent&gt;` section and other spring boot dependencies, then it works fine and able to replace the token. But still not sure how to fix this by keeping spring boot.

Maven resource filtering not working - because of spring boot dependency

Today I tried the [latest jdk9 Build 113](https://jdk9.java.net/download/) and tried to compile [my project](https://github.com/graphhopper/graphhopper/) with the latest Maven 3.3.9

These are the commands (found partially [via twitter](https://twitter.com/chriswhocodes/status/642646126689132544))

    export MVN_OPTS=&quot;-Dmaven.compiler.fork -Dmaven.compiler.executable=/somewhere/Downloads/jdk-9/bin/javac&quot;
    export JAVA_HOME=&quot;/somewhere/Downloads/jdk-9&quot;
    mvn clean install

But I get [this error](https://gist.github.com/karussell/aff591db1e46a3d2aafa12f8b4dd2f8d) ... in short:

**What is the correct maven configuration or parameters to use for JDK9?**

    $ mvn --version
    Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T17:41:47+01:00)
    Maven home: /home/somewhere/Downloads/maven
    Java version: 9-ea, vendor: Oracle Corporation
    Java home: /home/somewhere/Downloads/jdk-9
    Default locale: en_US, platform encoding: UTF-8
    OS name: &quot;linux&quot;,...


Is Maven ready for JDK9?

I&#39;m trying to compile my [`maven`][1] project using [`Java 10`][2] but I&#39;m having trouble. In my IDE (`IntelliJ IDEA`) everything compiles and runs just fine under `Java 10`. I installed the latest `maven` version `3.5.4` and pointed my `JAVA_HOME` to the `JDK 10`:

    $ mvn --version
    Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T20:33:14+02:00)
    Maven home: C:\Maven\bin\..
    Java version: 10.0.2, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk-10.0.2
    Default locale: en_US, platform encoding: Cp1252
    OS name: &quot;windows 10&quot;, version: &quot;10.0&quot;, arch: &quot;amd64&quot;, family: &quot;windows&quot;

The `maven` command I use is:

    mvn package -Dmaven.test.skip

In my `pom.xml` I had the following for `Java 8` which worked fine:

    &lt;properties&gt;
    	&lt;project.build.sourceEncoding&gt;UTF-8&lt;/project.build.sourceEncoding&gt;
    	&lt;maven.compiler.source&gt;1.8&lt;/maven.compiler.source&gt;
    	&lt;maven.compiler.target&gt;1.8&lt;/maven.compiler.target&gt;
    	&lt;libraries.directory&gt;libraries&lt;/libraries.directory&gt;
    &lt;/properties&gt;

For `Java 10` I changed it to the following:

    &lt;maven.compiler.source&gt;10&lt;/maven.compiler.source&gt;
    &lt;maven.compiler.target&gt;10&lt;/maven.compiler.target&gt;

This does not work, just like using `1.10` as the version for the source and target compiler.

The full debug logging output (`-X` command line switch) is the following:

Maven: Invalid target release: 10

What is the correct way of specifying Java 11 as the version to be used in Spring (or Spring Boot) pom.xml file?

I.e., what value do I need to put in the `java.version` property of the pom?

For Java 8 we use `1.8`, just like [the documentation shows][1], for Java 9 it&#39;s `1.9`.

I&#39;m not sure if Java 11 would be `1.11` (although it seems unlikely), and I&#39;ve seen it specified as just `11` when using `maven-compiler-plugin`, however I&#39;m not using the compiler plugin.

e.g. 

    &lt;plugin&gt;
        &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
        &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt;
        &lt;version&gt;3.8.0&lt;/version&gt;
        &lt;configuration&gt;
            &lt;release&gt;11&lt;/release&gt;
        &lt;/configuration&gt;
    &lt;/plugin&gt;


I&#39;ve searched around and couldn&#39;t find the answer, as pretty much any documentation I&#39;ve read as well as blog posts related to the Java version only show versions 8 or 9.

So what should I use? `1.11` or just `11`?

I tried both and my web server seems to start correctly and compile correctly (IntelliJ shows `Information:javac 11.0.2 was used to compile java sources`) however I&#39;m not entirely convinced that changing the `java.version` value is doing anything, because I can set it to e.g. `100` and everything works fine.

The only related questions I could find are: [Minimum Spring version compatible with Java 11][2], [Spring Boot fails due to a Hibernate error after migrating to JDK 11][3] and [Spring 4.3.x with OpenJDK 11][4], but they don&#39;t really shed any light.

How to specify Java version in Spring/Spring Boot pom.xml?

Getting unknown error at Line 1 in `pom.xml` in Eclipse IDE.
It was working fine till yesterday, but all of a sudden after updating my project from master and after fixing merge conflicts getting &quot;Unknown error&quot; in pom.xml.
Except me, none of my teammates are facing this issue. I also changed the workspace, deleted cache but still no luck. 

I am using the h2 database for this project, in spite of inserting values in data.sql, it is not picking up any values and inserting into h2 DB tables. Before this issue, it was working fine. I feel its due to the issue in pom.xml, I am not sure though. Please help

I deleted the existing project and took the latest code from master. After that deleted .m2 folder under users including the repository folder.  I did update project and enabled Forced update of snapshots/releases, maven clean and maven build. But nothing helps.

pom.xml

Should remove unknown error in pom.xml and also I must be able to populate values in H2 db.

Why am I getting Unknown error in line 1 of pom.xml?

I&#39;m installing a package that has Maven dependency and get a DependencyResolutionException when I try to clean it. 
After cloning it, I navigate to the directory and run the following to install it with no error:

```
mvn install:install-file -Dfile=./lib/massbank.jar -DgroupId=massbank  -DartifactId=massbank -Dversion=1.0 -Dpackaging=jar
mvn install:install-file -Dfile=./lib/metfusion.jar -DgroupId=de.ipbhalle.msbi  -DartifactId=metfusion -Dversion=1.0 -Dpackaging=jar
```

Then:

```
mvn clean package 
```

with the following console output:

```

I can post the output of the debug logging switch if necessary, but it&#39;s quite long. I can also post the pom.xml, however it refers to the repositories as required from what I can tell.

I&#39;ve searched for similar posts, but none seem to contain the same series of errors or similar. Can someone help me decipher these errors?

Thanks!
