Bug 318527

Description Simon Hobbs 2010-06-30 19:20:04 EDT

Build Identifier: 20100617-1415

Have a basic maven based project checked out from SVN.  It was building in eclipse without problems. The, out of the blue, nothing would build, and it cant resolve classes.  The Error log shows:

org.eclipse.core.runtime.CoreException: Local configuration cannot be nested in a directory.

Now the project wont build in that its not showing any files in the explorer thing as having errors, but if I open any source file, almost everything is "xxx cannot be resolved to a type", and not even clean works (just gives that error, doesnt even clean the class files).

The project in question is a simple example sub project of mybatis which I used the m2 checkout from SCM to bring into eclipse some days ago. I have to build the war using "mvn -Pdev war:war", I could not get elcipse to do this.  No idea if this has any bearing on it.

-- Configuration Details --
Product: Eclipse 1.3.0.20100617-0520 (org.eclipse.epp.package.reporting.product)
Installed Features:
 org.eclipse.platform 3.6.0.v20100602-9gF78GpqFt6trOGhL60z0oEx3fz-JKNwxPY


Reproducible: Always

Steps to Reproduce:
1.I have no idea what broke the project with this error.
2.I have no idea how to fix this problem and get the project working again.
3.I found similar bugs with the same message, but no work arounds, and its supposed to be fixed in this version of eclipse.
I tried to sumbit this bug directly from eclipse, but I just get: "submit failed: An unknown repository error has occured: match failed" which gives me no clue why, so had to use the web form instead.
