no plugin found for prefix 'eclipse' in the current project

[mohana krishna]

When i try to execute the follwoign command , i am getting the following error.

No plugin found for prefix 'eclipse' in the current project and in the plugin groups[org.eclipse.eclipse, org.apache.maven.plugins,org.codehaus.mojo]

I tried adding some plugin in pom.xml and googled but nothing works.

Please let me know how to resolve the issue.

What was the command line?

mvn eclipse:clean

It's likely that your POM wasn't used to set up for Eclipse. Try this goal:

mvn eclipse:eclipse

That will generate the necessary Eclipse project files and should download the Maven Eclipse plugin, if needed.

However, what exactly did you expect from "eclipse:clean"? Generally a simple "mvn clean" would be better.

[mohana krishna]

mvn clean is working fine.  Following some document so used mvn eclipse:clean.
But mvn eclipse:eclipse also not working getting the same error as earlier.

How can i fix this issue.

Tim Holloway , Thanks for your reply.

Did you include the plug-in in your POM?

Well!

It turns out that the eclipse plugin for Maven was retired in 2015 and has not been maintained since. I don't upgrade my copy of Maven very often, and it's likely that my copy of the plugin downloaded long ago and still lives there since Maven doesn't have an automatic archive cleaning mechanism.

The recommended alternative to the Maven Eclipse plugin is the Eclipse m2e plugin for Eclipse itself, available from the Eclipse Marketplace (on the Help menu, as I recall).

So forget Maven command-line goals beginning with "eclipse:", they are no longer supported. Use Eclipse itself. And the "mvn clean" on the command line.

In place of running "mvn eclipse:eclipse" to convert a Maven project for Eclipse support, just import the Maven project into Eclipse. If it gives you any trouble, I believe that there's a "convert to Maven" option on the Project Context Menu. If m2e is installed.
