sbt 0.13.1 and junit-interface 0.10 doesn't run JUnit tests

[applitect]

I have a project where we have lots of unit tests written. We've recently upgraded to sbt 0.13 and now our unit tests don't run. If I add the following to my build.sbt:

crossPaths := false

then it picks up the tests and runs successfully.

I built my own version of the plug-in and put in some debugging statements and then turned on global debugging within the build.sbt and it appears that the JUnitRunner is never even instantiated when crossPaths is defaulted to true.

Sorry, my observation seems to be a red herring. I'm having trouble reproducing things, which leads me to believe that my IDE and SBT are working at cross-purposes.

If it's of any value - this worked for me: I had a multi-module project with one pure java module (with only JUnit tests), and I couldn't get sbt to run this module's JUnit tests until I set crossPaths := false for this module.

Just chiming in - this also worked for me. Scala 2.11.7 SBT 0.13.8 java sources and java junit tests won't run without "crossPaths := false"

Thanks for the crossPaths hint. I've been able to solve this: http://stackoverflow.com/questions/28174243/run-junit-tests-with-sbt/34490115#34490115

Looks like I had the same problem, but running on sbt 0.13.8 but scala 2.10.4 and "com.novocode" % "junit-interface" % "0.11" and I had to disable crossPaths as well before the JUnit Tests were detected.

loadedTestFrameworks showed the JUnit Testrunner, but the test files themselves were not shown in definedTests.

Digged a bit deeper and the effect of switching the property crossPaths is that the compile task returns slightly different objects. In the sbt.inc.MAnalysis object the apis.internal HashMap contains tuples containing my test files, however in the case of crossPaths := true the value xsbti.api.Source contains nothing under api.definitions, which is what Tests.discover reduces all entries to.

I found that while SBT 0.13.16 does not run JUnit tests that have crossPaths := false, SBT 1.0.1 DOES run them. Both with junit-interface 0.11, on the same build file.

I just happened across this issue trying to understand why my JUnit tests stopped running when I moved from SBT 1.2.8 to 1.3.13 (both with junit-interface 0.11).

It turns out the crossPaths := false solution also works in the case of SBT 1.3.. I'll open another issue linking to this one with the heading "SBT 1.3. and junit-interface 0.11 not running JUnit tests" to help anyone searching in the future.

So I've had a similar issue on coursier/interface. There is an interface-test module that has java test and runs them using the junit-interface plugin.

crossPaths := false also fixed this for me, but more importantly, tests were still not running on the JVM 17.

On JVM 11:
