Hello,

I have the following problem with MyEclipse IDE 4.0.3:

When importing a project with Spring Capabilities I got errors:
Errors during build.
Errors running builder “MyEclipse Spring Project Builder” on project knight.
An error occurred while traversing resources.

I does not seem to cause any trouble, but you never know…

Here are my Config Details (I’m using 4.02, updated to 4.0.3) and the Eclipse log stacktrace.
I can send you a small project which reproduces the problem.

Regards
Stefan

Yes please send the sample project to support@genuitec.com ATTN Riyad, with a link to this post so I know why I’m getting the file. I’ll load it up over here and see what is going on first hand.

BTW your config (eclipse/myeclipse) looks fine.

Hello Riyad,

I just send you the email with the small sample project (The KnightOfTheHolyGrail sample from “Spring in Action”).

While preparing that sample I have noticed that the NPE problem does not occure until you import a second project in our MyEclipse session. The first time, everything seems fine. So you can reproduce the issue when you import the project, delete it and the import it again.

Regards
Stefan

Odd, thanks for the heads up, I’ll try it.

Stefan,
I was able to reproduce the issue, but after discussing it with one of the developers, if you simply restart MyEclipse, you can then work with the project without incident. It’s a (very odd) bug that is already fixed internallyl. Sorry for the inconvenience.

More information:

This problem only occurs after importing an existing spring project into your workspace; the reason being that the spring model was not refreshed correctly on import.

As Riyad mentioned, the solution is to either restart MyEclipse or simply close and reopen the project. This fix for this issue made it to ME 4.1m1 (be advised m1 is a milestone build and not recommended for production use)

Best,
Brian.
