An internal error occurred during: "Updating Maven Project

Question

> An internal error occurred during: \"Updating Maven Project\".
> Unsupported IClasspathEntry kind=4


        

Answer 1

Here is what worked for me: After the steps posted in Answer 21 above (the last being Convert to Maven Project), I did:

1. mvn eclipse:eclipse - this regenerates your .project and .classpath files (both of which were blown away by mvn eclipse:clean in step (2) above)

2. In Eclipse, I right-clicked my project(s) and then Maven > Update Project

I did not see the Unsupported IClasspathEntry kind=4 message anymore :)

Answer 2

This is all you need:

1. Right-click on your project, select Maven -> Disable Maven Nature.
2. Open you terminal, go to your project folder and do “mvn eclipse:clean”
3. Right click on your Project and select “Configure -> Convert into Maven Project”

Answer 3

1. Switch to terminal and type command mvn eclipse:clean
2. Right-click on you project, select Maven -> Update Project

Okay, everything is settled

Answer 4

Revert back to an earlier commit/change fixes the problem.... so it could be some corrupted project/mvn file issue, somehow. So, I followed the steps to clean up and then import the project.It worked after a couple attempts.
