MalteB,
Do you get the same error (An internal error occurred during: “Creating maven-archetype-quickstart”. )?

Can you go to File > Switch Workspace > Temp and try creating a new Mave Java Project. Do you face the same issue?

[MalteB]

Hi Nipun,

yes, i got exactly that error.

MalteB,
I have been unsuccessful in reproducing this issue at my end. Could you please download MyEclipse 7.0M1 and test this again. I hope that fixes this issue for you.

[MalteB]

Hi Nipun,

unfortunately i face the same problem with myeclipse version 7.0 M2.

It’s a completely new installation, so the question seems to be which properties from older versions will be taken over, or if some system path entries (maven 1.0) might cause this problem?

Any help is highly appreciated.

kind regards
MalteB

Hi Nipun,

problem solved. It was a misconfiguration taken over from an older myeclipse installation.

Thanks
