Could not calculate build plan: Plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved

Question

I got the following error message when I tried to create a Maven project in eclipse. Many have posted about proxies in settings.xml file and also flush the .m2 folder forcin

Answer 1

In my case the error was: CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 ....

With eclipse luna from console in the pom.xml folder

mvn clean
mvn install

With Juno I had to had this to my pom.xml

  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
          <version>2.3.2</version>
          <configuration>
            <!-- put your configurations here -->
          </configuration>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>

And then

mvn install

And then from eclipse right click>maven>update project * Once the plugin is donwloaded you can remove the plugin from your pom.xml

Answer 2

I had this error, I follwed below three steps to solve,

1). check proxy settings in settings.xml refer,

2). .m2 diretory to release cached files causing problems

3) Point your eclipse to correct JDK installation. Refer No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK? to know how

Answer 3

I have had this issue and I resolved it by following the next step:

1- Close Eclipse.

2- Go to user directory and delete the .m2 directory.

3- Open Elipse.

4- Right click on the project -> Run as -> maven install
