It seems to be fixed in current version of maven-war-plugin, so just specifying:

        &lt;plugin&gt;
            &lt;artifactId&gt;maven-war-plugin&lt;/artifactId&gt;
            &lt;version&gt;2.3&lt;/version&gt;
        &lt;/plugin&gt;

fixed it for me. (See the last answer (20/Sep/12 4:37 AM) from Anders Hammar on https://issues.apache.org/jira/browse/MWAR-248.)

I got rid of this warning in maven 3.0.1 with the following build configuration (i believe perhaps web.xml is added to the project by other means, and should&#39;t be packaged by default):

&lt;!-- language: xml --&gt;

    &lt;project&gt;
    	...
    	&lt;build&gt;
    		&lt;plugins&gt;
    			&lt;plugin&gt;
                    &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
                    &lt;artifactId&gt;maven-war-plugin&lt;/artifactId&gt;
                    &lt;version&gt;2.6&lt;/version&gt;
    				&lt;configuration&gt;
    					&lt;packagingExcludes&gt;WEB-INF/web.xml&lt;/packagingExcludes&gt;
    				&lt;/configuration&gt;
    			&lt;/plugin&gt;
    		&lt;/plugins&gt;
    	&lt;/build&gt;
    	...
    &lt;/project&gt;


I&#39;ve filed the following bug report regarding this issue: https://issues.apache.org/jira/browse/MWAR-248

I was reading an article linked from a slashdot story, and came across this little tidbit:

&gt; Take the latest version of Java, which
&gt; tries to make null-pointer checking
&gt; easier by offering shorthand syntax
&gt; for the endless pointer testing. Just
&gt; adding a question mark to each method
&gt; invocation automatically includes a
&gt; test for null pointers, replacing a
&gt; rat&#39;s nest of if-then statements, such
&gt; as:
&gt; &lt;code&gt;&lt;pre&gt;
&gt;     public String getPostcode(Person person) {
&gt;       String ans= null;
&gt;       if (person != null) {
&gt;         Name nm= person.getName();
&gt;         if (nm!= null) {
&gt;           ans= nm.getPostcode();
&gt;         }
&gt;       }
&gt;       return ans
&gt;     } &lt;/pre&gt;&lt;/code&gt;
&gt; 
&gt; With this:
&gt; &lt;code&gt;&lt;pre&gt;
&gt; public String getFirstName(Person person) {
&gt;       return person?.getName()?.getGivenName();
&gt;     } &lt;/pre&gt;&lt;/code&gt;

I&#39;ve scoured the internet (okay, I spent at least 15 minutes googling variations on &quot;java question mark&quot;) and got nothing. So, my question: is there any official documentation on this? I found that C# has a similar operator (the &quot;??&quot; operator), but I&#39;d like to get the documentation for the language I&#39;m working in. Or, is this just a use of the ternary operator that I&#39;ve never seen before.

Thanks!

When building WAR package using Maven 2.1.1, I get this warning message:

    [WARNING] Warning: selected war files include a WEB-INF/web.xml which will be ig
    nored
    (webxml attribute is missing from war task, or ignoreWebxml attribute is specifi

Is there a way to eliminate it? It doesn&#39;t fail the building process, but I just do not want to see it.

I&#39;ve read through several posts about using this, but must be missing something as it&#39;s not working for me. My activity A has launchmode=&quot;singleTop&quot; in the manifest. It starts activity B, with launchmode=&quot;singleInstance&quot;. Activity B opens a browser and receives and intent back, which is why it&#39;s singleInstance. I&#39;m trying to override the back button so that the user is sent back to the activity A, and can then press Back to leave the activity, rather than back to activity B again.

    // activity B
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event)  {
     if (android.os.Build.VERSION.SDK_INT &lt; android.os.Build.VERSION_CODES.ECLAIR
      &amp;&amp; keyCode == KeyEvent.KEYCODE_BACK
      &amp;&amp; event.getRepeatCount() == 0) onBackPressed();
     return super.onKeyDown(keyCode, event);
    }
    @Override
    public void onBackPressed() {
     startActivity(new Intent(this, UI.class)
     .setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK));
     return;
    }

After returning from the browser, the stack is...
A,B,Browser,B

I expect this code to change the stack to...
A
... so that pressing back once more takes the user back to the Home Screen.

Instead it seems to change the stack to...
A,B,Browser,B,A
...as though those flags aren&#39;t there.

I tried calling finish() in activity B after startActivity, but then the back button takes me back to the browser again!

What am I missing?


How do you use Intent.FLAG_ACTIVITY_CLEAR_TOP to clear the Activity Stack?

What is the difference between `List&lt;? super T&gt;` and `List&lt;? extends T&gt;` ?

I used to use `List&lt;? extends T&gt;`, but it does not allow me to add elements to it `list.add(e)`, whereas the `List&lt;? super T&gt;` does.

I have to know if `Object` is String or any other class type, how can I do it? Currently I do it like below, but its not very good coding.

    try {
    	String myString = (String) object;
    	// do stuff here
    } catch(Exception e) {
    	// it wasn&#39;t string, so just continue
    }

How can I know if Object is String type object?

I&#39;m working within the traditional Maven Java project structure inside IntelliJ, e.g.

    main/java/com/x/y
    test/java/com/x/y

When I create a class called Foo in _main/java/com/x/y_ using IntelliJ I would like to automatically have a file called FooTest.java created in _test/java/com/x/y_.

In Eclipse there is a button on the toolbar that will do much of the work involved in creating a skeleton test class, does anyone know of something similar in IntelliJ?

Thanks,



Create Test Class in IntelliJ

In our project we are writting a test to check if the controller returns the right modelview

    @Test
    	public void controllerReturnsModelToOverzichtpage()
    	{
    		ModelAndView modelView = new ModelAndView();
    		KlasoverzichtController controller = new KlasoverzichtController();
    		modelView = controller.showOverzicht();
    		
    		assertEquals(&quot;Klasoverzichtcontroller returns the wrong view &quot;, modelView.getViewName(), &quot;overzicht&quot;);
    	}

This returns the exception null.

We are now configuring the @contextconfiguration but we don&#39;t know how to load the right xml who is located at src\main\webapp\root\WEB-INF\root-context.xml

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration
    public class TestOverzichtSenario{
    ....

[This documentation isn&#39;t clear enough to understand][1]

Any suggestion on how to make sure the contextannotation loads the right xml?


**Edit v2**

I copied the configuration .xml files from the webINF folder to 

    src\main\resources\be\..a bunch of folders..\configuration\*.xml 

and changed the web.xml in webinf to 

    &lt;param-name&gt;contextConfigLocation&lt;/param-name&gt;
    &lt;param-value&gt;
    			classpath*:configuration/root-context.xml
    			classpath*:configuration/applicationContext-security.xml
    		&lt;/param-value&gt;

and now get the error

I know there is a list of all predefined Maven properties (you know like `project.build.sourceEncoding`, or `project.build.sourceDirectory`). I once saw the list but I just can&#39;t find it again. 

Where is the list of predefined Maven properties

is there a tool that can list third party &quot;packages&quot; that contain (third party) classes referenced in the JAR ? Let say that it would recognize what is &quot;home&quot; package from JAR file definition and it would print out a list of fully qualified names of third party classes up to 3rd level that were referenced within the JAR.

    org.apache.commons  
    org.apache.maven
    javax.servlet.jsp
    org.eclipse.persistence
    org.apache.jackrabbit

the purpose is that I need to find maven dependencies for that JAR file and deploy it as a maven artifact. 

How to list dependencies of a JAR

I received a source code bundle. Inside the src directory tree there are some properties files(.properties) which I want to keep in the output jar in the same place. e.g: I want  

    src/main/java/com.mycompany/utils/Myclass.java 
    src/main/java/com.mycompany/utils/Myclass.properties

 
to stay the same in the jar:

    com.mycompany/utils/Myclass.class 
    com.mycompany/utils/Myclass.properties

without needing to add the properties file it to separate resources folder. Is there a way to I tell this to maven?


In maven how can I include non-java src files in the same place in the output jar?

Is there an argument when calling a maven build to specify an alternate file in place of the standard pom.xml file name?

Basically, I have a need to run the *test* goal of my maven build with a variety of configurations.  Right now I am having to use an external script to update the standard pom with this configurations, then revert the file after.  I would much rather just be able to maintain several seperate configuration files and call maven with the specific one I need.

What I am wondering is if there is some way to override the pom.xml such as

    mvn clean test   (uses standard pom.xml)
    mvn clean test -Dmaven.source=alternate.xml
    mvn clean test -Dmaven.source=alternate2.xml

Is this possible?



Maven alternate pom

I use maven conventions for source paths (src/main src/test) and i have my sql scripts in src/main/resources/scripts.

I want to run my app with H2 memory and i&#39;d like to use the jdbc url to initialize my db :

    database.url=jdbc:h2:mem:;INIT=RUNSCRIPT FROM &#39;src/main/resources/scripts/create.sql&#39;;

My problem is that this relative path (src/main/... ) does not work, and that H2 won&#39;t crash if the init=runscript command targets nothing.

Does someone know what is the path i should use to make this work ?

Thanks

Maven `dependency:analyze` complains about the dependencies in my project. How does it determine which are unused and which are undeclared? What should I do about them?

Example:

    $ mvn dependency:analyze 
    ...
    [WARNING] Used undeclared dependencies found:
    [WARNING]    org.slf4j:slf4j-api:jar:1.5.0:provided
    [WARNING]    commons-logging:commons-logging:jar:1.1.1:compile
    [WARNING]    commons-dbutils:commons-dbutils:jar:1.1-osgi:provided
    [WARNING]    org.codehaus.jackson:jackson-core-asl:jar:1.6.1:compile

    ...
    [WARNING] Unused declared dependencies found:
    [WARNING]    commons-cli:commons-cli:jar:1.0:compile

    [WARNING]    commons-collections:commons-collections:jar:3.2:provided
    [WARNING]    javax.mail:mail:jar:1.4:provided


Note:
A lot of these dependencies are used in my runtime container and I declared them as provided to avoid having the same library on the classpath twice with different versions. 


What are unused/undeclared dependencies in Maven? What to do with them?

I’m trying to find a “generic” way of excluding a transitive dependency from being included without having to exclude it from all the dependencies that depend on it.  For example, if I want to exclude slf4j, I do the following:


      &lt;dependency&gt;
        &lt;groupId&gt;org.hibernate&lt;/groupId&gt;
        &lt;artifactId&gt;hibernate-jmx&lt;/artifactId&gt;
        &lt;version&gt;3.3.2.GA&lt;/version&gt;
        &lt;exclusions&gt;
          &lt;exclusion&gt;
            &lt;groupId&gt;org.slf4j&lt;/groupId&gt;
            &lt;artifactId&gt;slf4j-api&lt;/artifactId&gt;
          &lt;/exclusion&gt;
        &lt;/exclusions&gt;
      &lt;/dependency&gt;
      &lt;dependency&gt;
        &lt;groupId&gt;org.hibernate&lt;/groupId&gt;
        &lt;artifactId&gt;hibernate-entitymanager&lt;/artifactId&gt;
        &lt;version&gt;3.4.0.GA&lt;/version&gt;
        &lt;type&gt;jar&lt;/type&gt;
        &lt;exclusions&gt;
          &lt;exclusion&gt;
            &lt;groupId&gt;org.slf4j&lt;/groupId&gt;
            &lt;artifactId&gt;slf4j-api&lt;/artifactId&gt;
          &lt;/exclusion&gt;
        &lt;/exclusions&gt;
      &lt;/dependency&gt;

This is partly to clean up the pom file, partly to avoid issues in the future with people adding dependencies that depend on that excluded dependency — and forgetting to exclude it.

Is there a way?


Is there a way to exclude a Maven dependency globally?

I want to deploy sources and javadocs with my snapshots. This means that I want to automize the following command:

    mvn clean source:jar javadoc:jar deploy

Just to execute:

    mvn clean deploy

I don&#39;t want to have javadoc/sources generation executed during the `install` phase (i.e. local builds).

I know that source/javadoc plugins can be synchronized with the execution of the `release` plugin but I can&#39;t figure out how to wire it to the snapshots releases.
