Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile)

I am using Maven 3.0.5 and Spring Tool Source 3.2 with Maven plugin installed. When I try to do 'Run As---> Maven install', I am getting the following error:

During maven install my goal is war:war to make WAR of my application.

Deleting full .m2/repository local repository solved my problem.

Or else you need to know what plugins are you using exactly with their dependencies as one of the plugin suffered a problem while downloading.

Deleting full .m2 local repository solved my problem, too.

If you don't know where it is, the locations are:

Unix/Mac OS X – ~/.m2/repository
Windows – C:\Documents and Settings\{your-username}\.m2\repository 
        ( %USERPROFILE%\.m2\repository too, as suggested by **MC Empero** )

I am adding more points to the solution by @Rushi Shah

mvn clean install -X helps to identify the root cause.

Some of the important phases of Maven build lifecycle are:

clean – the project is clean of all artifacts that came from previous compilations compile – the project is compiled into /target directory of project root install – packaged archive is copied into local maven repository (could in your user's home directory under /.m2) test – unit tests are run package – compiled sources are packaged into archive (JAR by default)

The 1.6 under tag refers to JDK version. We need to ensure that proper jdk version in our dev environment or change the value to 1.7 or 1.5 or whatever if the application can be supported in that JDK version.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.0</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
        </plugin>
    </plugins>
</build>

We can find the complete details on Maven build lifecycle in Maven site.

I had the same problem, check the installed jre used by Maven in your Run Configuration...

In your case, I think that the maven-compiler-plugin:jar:2.3.2 needs a jdk1.6

To do this : Run Configuration > YOUR_MAVEN_BUILD > JRE > Alternate JRE

Hope this helps.

Sometimes it is caused due to the project points to JRE rather than JDK.So try this,

1.Right Click on project -->Build Path --> Configure Build Path -->Add Library -->JRE System Library -->Environments--> Installed JREs-->Point to java folder in c: drive (Windows) and select JDK folder and ok.

2.Remove the already present JRE from build path.

Sometimes this issue comes because the java.version which you have mentioned in POM.xml is not the one installed in your machine.

<properties>
	<java.version>1.7</java.version>
</properties>

Ensure you exactly mention the same version in your pom.xml as the jdk and jre version present in your machine.

Usually, define maven-compiler-plugin is sufficient enough. add the following to your compiler plugin definition.

<plugin>
    <inherited>true</inherited>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>				
</plugin>

None of the other answers suggests downloading just the missing plugin.

Before you delete your whole .m2 repository and re-download all project dependencies and all plugins, you may want to try:

mvn dependency:resolve-plugins

That will download just the missing plugins.

I had this problem once, and this is how i resolved it:

Step-1 Clean your

.m2/repository

Step-2 execute the maven command(for example mvn clean verify) from the terminal at the current project location(where your project's pom.xml file exist) instead of running maven from eclipse.

Either remove the below code from the pom.xml or correct your java version to make it work. > > maven-compiler-plugin > 3.0 > > 1.6 > 1.6 > >

I think you have Two ways to solve this problem

01. Set Properties

• Set Java Build Path as jdk

> Right click project ->Java Build Path ->Select Libraries tab ->Select JRE System Library ->Click Edit button ->Click Installed JREs-> add tick to box ->click Edit ->Click Directory->Select jdk

• Specifi which kind of jdk version you installed

> Right click project ->Project Facets ->tick java and select java version->Apply ->Ok

• Update project

> Right-click on "project"->Go to Maven->Update

02.Delete .m2 file

If you can't solve your problem using above two topic get this action Close your project. Delete your full .m2 folder

How to fined .m2 file(windows)

> Go to Local Disk(C) ->Users ->Select your PC name ->.m2 file

Java 9 incompatible

I got this error when trying to calling mvn install on a project.

I had installed Java 9 on macOS as well as Java 8 Update 144. My Maven project was apparently invoking Java 9 and failing. Removed Java 9 from my Mac, leaving just Java 8 in place. Maven is now happily building my project to successful completion.

Using Apache Maven 3.5.0 on macOS Sierra.

Actually, if you do not want to delete your local .m2/repository/... and you are have a downloaded copy of Maven from Apache, you can have Eclipse /STS use that external Maven and you can edit the {maven}\conf\settings.xml to point your localRepository to a new empty location.

<localRepository>C:\java\repository</localRepository>

Of course, you will have a new repository with all of the maven source downloads in addition to your previous .m2 location.

check the property endorsed.dir tag in your pom.xml.
I also had this problem and I fixed by modifying the property.

Example:

<endorsed.dir>${project.build.directory}/endorsed</endorsed.dir>  

• Download maven compiler plugin jar from your central repositoy n try
• If it is still failing check your jdk version, it is because of your application is built on diff jdk version

For me, restarting Eclipse got rid of this error!

I renamed the .m2 directory, this didn't help yet, so I installed the newest sdk/jdk and restarted eclipse. This worked.

It seems an SDK was needed and I only had installed a JRE.

Which is weird, because eclipse worked on the same machine for a different older project.

I imported a second maven project, and Run/maven install did only complete after restarting eclipse. So maybe just a restart of eclipse was necessary.

Importing yet another project, and had to do maven install twice before it worked even though I had restarted eclipse.

Maybe there is a file got locked in the target folder

Check the JDK version in pom.xml

<properties>
	<java.version>11</java.version>		
</properties>

Sometimes it may be due to the use of wrong java version. Check the java version supported for the tool you are going to use. In my case, it was due to java 8 be used on maven build and it supposed to be JAVA 11.

Change the version before do mvn clean install

by command for Linux export JAVA_HOME=<path>

Maybe you can add this dependency to your pom.xml. I use this method and solve the problem！

<dependency> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-resources-plugin</artifactId> 
    <version>2.3.2</version> 
</dependency>

for the new users on Mac os , find out .m2 folder and delete it, its on your /Users/.m2 directory.

you wont get to see .m2 folder in finder(File Explorer), for this user this command to Show Mac hidden files

$ defaults write com.apple.finder AppleShowAllFiles TRUE

after this press alt and click on finder-> relaunch, you can see /Users/.m2

to hide files again, simply use this $ defaults write com.apple.finder AppleShowAllFiles false

It's really incredible to be oblige to erase whole .m2/repository content. I suggest to type this command (On Windows) :

> mvn clean > > mvn -X package > my_log_file.log

The last command enable Debug option et redirect output to a file. Open the file and search ERROR or WARNING key words. You can find this kind of expression :

DEBUG] =======================================================================
[WARNING] The POM for javax.servlet:javax.servlet-api:jar:4.0.0 is invalid, transitive dependencies (if any) will not be available: 1 problem was encountered while building the effective model for javax.servlet:javax.servlet-api:4.0.0

It's esay in this case to understand you have just to delete directory C:\Users\vifie.m2\repository\net\java\jvnet-parent\3

Relaunch compilation, packaging and so on :

> mvn package

WARNING disappear just because you delete POM file corrupted at the good location and maven re download it. Normally the new POM file is better.

Often debug mode give you messages with more comprehensive details.

Why I redirect log to a file : Simply because on Windows console don't have enough buffer to store all lines and often you cannot see all lines.

We tried everything listed so far and it still failed. The error also mentioned

> (default-war) on project utilsJava: Error assembling WAR: webxml > attribute is required

The solution that finally fixed it was adding this to POM:

<failOnMissingWebXml>false</failOnMissingWebXml>

As mentioned here Error assembling WAR - webxml attribute is required

Our POM now contains this:

<plugin>
<inherited>true</inherited>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>${maven-war-plugin.version}</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
<warName>${project.artifactId}</warName>
<attachClasses>true</attachClasses>
</configuration>
</plugin>  

It is because your Jenkins not able to find setting file. If deleting .m2 not work, try below solution

In my case, a .properties file (Spring Boot's application.properties) contained an accentuated character at some point. As you can see, it was treated as critical error, due to this IOUtil.copy using a Reader as a source, so it decodes the byte stream while copying, which is always a good source of hard to guess exceptions.

It was a typo in the variableName which was leading me to this issue,

<finalName>${project.artifactId}</finalName>

Had the same issue while converting my project to JDK 11 The suggested removing the .m2/repository did not work Gone through almost all the suggestions mentioned on the internet but no luck

What I did was remove all the dependencies from the child module pom.xml and add them one by one again. This method was a success and worked like a charm

The problem I had was some of the dependency was changed in the new JDK 11 and need to separately add to the pom.xml. The codebase did not show any error even cleaning the .m2/repository did not. So had to follow use this solution

I got this when I unwittingly had two references to maven-war-plugin in my pom, one in and one in the executions section to get around the Eclipse Lifecycle issue. I fixed both to 3.3.2 and it worked just fine

I am using Intellij IDE and If you are getting this error don't use terminal. Use Maven tab on IDE and

Select your project and do these steps;

1. Click clean
2. Click install

It works for me

I have same problem and change fork tag in pom.xml from "true" to "false" and issue resolved.

<fork>true</fork>

i had the same problem and besides the above posts' configurations putting

			<plugin>
			<groupId>com.google.appengine</groupId>
			<artifactId>appengine-maven-plugin</artifactId>
			<version>1.9.32</version>
			<configuration>
				<enableJarClasses>false</enableJarClasses>
			</configuration>
			<executions>
				<execution>
					<goals>
						<goal>endpoints_get_discovery_doc</goal>
					</goals>
				</execution>
			</executions>
		</plugin>

in the plugins element in pom.xml. i think the problem was absence of execution -> goal "endpoints_get_discovery_doc" in some cases like mine, so this worked for me.
