Cannot run Junit tests from IDEA 13.0 IDE for imported gradle projects

Question

I have a Gradle project containing some java modules and one android module. Every thing seems working fine, the project builds and deploys on Android devices. But, I have a major issue. As I'm using IDEA for TDD. I have to run unit test from the IDE as usual but I get always an error message: Class not found: "[full.class.name]"

-> With dynamic.classpath=true: the generated command is:

C:\Program Files\Java\jdk1.7.0_17\bin\java" -Didea.launcher.port=7533 "-Didea.launcher.bin.path=C:\Program Files (x86)\JetBrains\IntelliJ IDEA 13.0\bin" -classpath "C:\Program Files (x86)\JetBrains\IntelliJ IDEA 13.0\lib\idea_rt.jar;C:\Program Files (x86)\JetBrains\IntelliJ IDEA 13.0\lib\util.jar" -Dfile.encoding=UTF-8 com.intellij.rt.execution.CommandLineWrapper C:\Users\[UserName]\AppData\Local\Temp\classpath9127004204172317095.tmp com.intellij.rt.execution.application.AppMain com.intellij.rt.execution.junit.JUnitStarter -ideVersion5 [full.class.name]

Answer 1

Jetbrains support team confirmed to me that this is a major bug and should be resolved by the next release 13.0.1. The release date is not defined yet.

The issue is caused by the Android-Gradle project.

Answer 2

Prior to run tests from IDEA just invoke cleanup by running "clean" task from Gradle. Hope this helps.

Answer 3

I got this same error when I didn't put my Java code in the expected default locations: src/main/java and src/test/java. Once I fixed that, I could run tests from IDEA or the commandline.
