"Plugin not found for prefix" error in Eclipse

eclipse, jetty, maven

Solution

It does not work for me from command-line either.

Can you check if it works after adding the following in `settings.xml` as documented?

<pluginGroups>
    <pluginGroup>org.mortbay.jetty</pluginGroup>
</pluginGroups>

Also note that there are two different versions of the plugin - the older maven jetty plugin and the newer jetty maven plugin.

Problem

In Eclipse I imported a maven-based project which uses maven jetty plugin. If I run `mvn jetty:run` from command line, everything works fine. If I add a run configuration in Eclipse and try to run it, I get the error message: ``` [ERROR] No plugin found for prefix 'jetty' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/home/eugene/.m2/repository), central (http://repo1.maven.org/maven2)] -> [Help 1] ``` ` In the Eclipe run configuration, I use: - Base directory: `${project_loc}` - Goal: `jetty:run` - Maven Runtime: External I read the [Help1] page. I don't have pluginGroup settings in maven configuration files, but I have the jetty plugin mentioned in pom.xml, so I guess everything should be fine (especially because everything works in command-line). I tried to "Run as > Maven clean" in Eclipse before executing the jetty run configuration, but it didn't help. Project compiles and passes all tests, only jetty:run does not work in Eclipse. Please help, I'm an Eclipse & Maven newbie. Thanks in advance.
