Eclipse Maven Jetty

I try to download projects http://svn.codehaus.org/jetty from SVN but received this error:

No marketplace entries found to handle Ex开发者_JS百科ecution exec-plugin-doc, 
in modules/jspc-maven-plugin/pom.xml in Eclipse.  

What doesn't mean marketplace? May be I doesn't correct install Eclipse or SVN connectors? Thanks.

With the limited info in the question, it looks like a similar problem to this one. If so, you may want to try with an older version of Eclipse.
