How to fix maven-dependency-plugin (goals “copy-dependencies”, “unpack”) is not supported by m2e in Eclipse

Recently when I imported a Maven Project in Eclipse Indigo, it was showing following error in the project – maven-dependency-plugin (goals “copy-dependencies”, “unpack”) is not supported by m2e.

The issue was coming because Eclipse M2E doesn’t support execution, more details are at .
However, if you build the project, it doesn’t cause any issue.

To resolve this error all you need to do is copy following code just before your closing tag of the build.

Copy
<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-dependency-plugin
	</artifactId>
	<versionRange>
		[2.0,)
	</versionRange>
	<goals>
		<goal>unpack</goal>
	</goals>
</pluginExecutionFilter>
<action>
	<ignore></ignore>
</action>
		</pluginExecution>
	</pluginExecutions>
</lifecycleMappingMetadata>
		</configuration>
	</plugin>
</plugins>
</pluginManagement>

Just save the project and error should be gone, if not you might need to Update the project from maven options.
