I have imported maven project in STS, when I run update update project I receive:

"Updating Maven Project". Unsupported IClasspathEntry kind=4

Is there a workaround for this?

This issue has been fixed in m2e 1.5.0 which is available for Eclipse Kepler (4.3) and Luna (4.4)

Please see

The problem is caused by the fact that STS (the Spring IDE/Eclipse), as well Eclipse and other Eclipse based IDE's, use the m2e(clipse) plugin but that eclipse:eclipse has been probably been run on the project. When m2e encounters a "var" .classpath entry, it throws this error.

The update sites are specified at the following url:

If you can't use m2e 1.5.0 for any reason, then :

  1. Disable the maven nature for the project (via the right-click menu)

  2. Run mvn eclipse:clean (while your project is open in STS/eclipse). Depending on the timing, you might need to do a refresh or two on the project before re-enabling the maven nature. You should be able to see that your project has lost it's Maven nature. (The eclipse:clean goal just deletes the .project, .classpath and .settings/ files/directories. You can also just remove those files (again while the project is open) instead of running mvn eclipse:clean.)

  3. Re-enable the maven nature. (Most of the time, this can be done by right-clicking on the project in question in the package explorer pane, and then choosing 'Configure'-> 'Convert to Maven Project')

Sometimes, even re-importing the Maven project will not work. Updating the project correctly in eclipse is not a deterministic process. The only 100% fail safe procedure I've found is:

  1. Disable Maven Nature, run mvn eclipse:clean, restart, cross your fingers and Pray 3 times.
  2. If this won't work, delete the project, run mvn eclipse:clean, re-import refresh, pray and use the force.
  3. If this still doesn't work, restart Eclipse, or even better your computer. While waiting for the reboot, you can make a random donation to fix your Karma. Repeat step 2 and don't forget to pray and control your anger. Anger leads to hate. Hate leads to suffering.
  4. Try all the other answers posted in this thread. You might need to try them all for 3 times at least before giving up.
  5. Format your Computer, re-install Eclipse and Maven. No need to pray anymore, all gods hate you anyway
  6. Delete your git project, burn the physical drive that stored the remote repository, and write your project from scratch.
  7. Find a time machine, travel to the past and convince yourself to follow another, non-programming career or at least to avoid Java

  • Does a build on command line work ? Which Maven version?
  • I have the same issue and i am not able to slove by this answer can you please see…
  • I had to try this twice to get it to work. The first time I tried it the "var" crept back into the .classpath file. I regenerated the files with mvn eclipse:eclipse and tried again. It worked the 2nd time.
  • It might help to remove manually from the .classpath file all the classpathentry with the kind attribute set to var.
  • It worked for me, but I had to do an extra "Refresh" before re-enabling the Maven nature (actually in my case "Configure as Maven Project" as it was a faceted project)
  • doesn't work anymore
  • I think you go the Eclipse versions wrong: Eclipse Kepler is 4.3 and Luna is 4.4
  • Thanks for this. Just a note for others, it's mvn eclipse:clean, not mvn clean (I got fooled by not paying close attention).
  • Ok. I have created src/java from cmd line, after importing project into Kepler. That was the case.
  • Tried it all, keep saying "Maven Dependency Management problem" or "NullPointerException"
