Re: [tycho-dev] java.lang.NoClassDefFoundError during local build for OS

[Gunnar Wagenknecht <gunnar@xxxxxxxxxxxxxxx>]

Found the root cause: I accidentally imported the test projects in Eclipse when using the Eclipse Import from Git wizard. This triggered generation of the "bin" folder and compilation of classes. 

After removing those I made further progress until this one:
>>>>>>>>>
Running org.eclipse.tycho.surefire.TestMojoTest
[warn] Both parameter 'skipTests' and 'maven.test.skip' are set, 'skipTests' has a higher priority!
Tests run: 10, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.019 sec <<< FAILURE! - in org.eclipse.tycho.surefire.TestMojoTest

	at org.eclipse.tycho.surefire.TestMojoTest.testSplitArgLineUnbalancedQuotes(TestMojoTest.java:50)
<<<<<<<<<

This looks like Maven command line is using a different version. I don't get the compile error in Eclipse with M2E calculating the class path. A mvn -U clean install specifically for the tycho-surefire-plugin solved the issue.

Looks like all is good now and I can continue with getting the its tests rolling on my machine.
