Can some one from myeclipse teaming respond my previous message??

schanamolu ,

Sorry that you are seeing this issue.

Can you give us some more information?

1. Can you please copy paste the entire contents of the Installation Details from MyEclipse > Installation Summary > Installation Details ? Scroll down the Installation Details window, to see the entire contents.

2. Can you clarify if you can successfully build the project using Maven outside of MyEclipse ?

3. Can you do a clean on the project (Project > Clean) and check if it helps resolve the issue?

4. If the clean does not help, can you please switch to a new workspace, copy the project and check if the issue persists.

Let us know how it works for you.
