maven-dependency-plugin (goals “copy-dependencies”, “unpack”) is not supported by m2e

Recently While importing one Maven project into Eclipse(Juno, m2e plug-ins is already installed in Eclipse). I was getting one error in project : maven-dependency-plugin (goals “copy-dependencies”, “unpack”) is not supported by m2e


Reason: Eclipse m2e does not support execution, by copying the below code in the build tag resolve the issue.

Example:

<build>
<COPY_CODE_HERE>
</build>

Code :

<pluginManagement>
<plugins>
<!--This plugin's configuration is used to store Eclipse m2e settings
only. It has no influence on the Maven build itself. -->
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>

<pluginExecution>
<pluginExecutionFilter>
<groupId>
org.apache.maven.plugins
</groupId>
<artifactId>
maven-antrun-plugin
</artifactId>
<versionRange>
1.7
</versionRange>
<goals>
<goal>run</goal>
</goals>
</pluginExecutionFilter>
<action>
<ignore></ignore>
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>

Save the project and it will resolve the issue, if not then Right click on your project and update Maven(Maven → Update Project... ).
