I recently imported a bunch of Maven projects(Ardor3D if it helps) into Eclipse, and for some reason, in all but the first project, there is a little red x mark next to the pom.xml file in the Package Explorer window indicating there is an error, however when I open the pom.xml, I can't find any error...thanks for any help!

  • Invalidate casches in your IDE and reimport project then rebuild it. – RMachnik Feb 26 '14 at 21:09
  • right click on that error and do quick fix, probably some eclipse conf issue – jmj Feb 26 '14 at 21:11
  • Just looked and it says "Description Resource Path Location Type Cannot read lifecycle mapping metadata for artifact org.apache.maven.plugins:maven-deploy-plugin:maven-plugin:2.8.1:runtime Cause: error in opening zip file pom.xml /ardor3d-animation line 1 Maven Project Build Lifecycle Mapping Problem" – abaratham Feb 26 '14 at 21:11

Check this link:

Why am I getting Unknown error in line 1 of pom.xml?

For me, after I hit this problem, I upgrade my STS from 4.0 to 4.7.1 and problem goes away, like someone also mentioned in that link.
