Please help me.

Answer 1

You can use m2e 1.5.0 from the market or you can use this approach:

• Switch to:

  Settings-> Click Maven-> Click Templates

Now you can view the list of templates, cancel all wtp templates ie m2e-wtp-activation ....

Now you can clear the project installation

Answer 2

Try to delete the .m2 folder on your computer and clean up the project, then it will automatically create it.

Next, check that the settings below are in the .project file

Next, check the settings in the .classpath file.

If nothing works above. Try using the version of Eclipse Luna, it will work. I had a problem with maven 3.5 with kepler, then I tried to use luna, it worked for me.

I hope this helps you!

Answer 3

Removing the m2e-wtp plugin fixed this for me (I don’t even know what it does or when I downloaded it).
