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.
<pluginManagement>
<plugins>
<!--This plugin's configuration is used to store Eclipse m2e settings only. It has no influence on the Maven build itself.-->

Just save the project and error should be gone, if not you might need to Update the project from maven options.
Thank you for posting.
Nice, thank you so much.
