test failures

[Rafał Krzewski]

Hi, I'm trying to build scala-ide locally and I'm getting test failures in org.scala-ide.sdt.core.tests:

Results :

Tests in error: 

  findReferencesInConstructorSuperCall(scala.tools.eclipse.findreferences.FindReferencesTests): Don't know how to convert element `layout` of type `class org.eclipse.jdt.internal.core.ResolvedBinaryMethod`

I'm getting this consistently on master and platform/juno in default profile and in scala-2.10.x

I'm on Linux x86_64, JDK 1.6.0_37-b06 (I've also tried JDK 7 but got a bunch more failures), Maven 3.0.4. 

Do these failures seem familiar? I'd be happy to dig around to fix it if necessary but need some directions :)

Cheers,

Hi Rafal,

Yes, this is a known problem when building the IDE under Linux. Although not ideal, you can get past this problem by either

* adding an @Ignore for the two failing test, or 

* by simply skipping running tests altogether, i.e., just pass -Dmaven.test.skip=true when building

Cheers,

  Mirco

Mirco and I spent some time looking at the problem (I was also seeing it on Linux). In a nutshell, the test was polluted by inaccurate results only visible on Linux. I'll make a pull request which change the test so it tests only what it is supposed to check, and create a ticket for the 'inaccurate' problem.

For now, add @Ignore for those 2 tests, the fix should appear shortly.

Thanks for pointing to this problem, I was getting a bit too used of working around it,
