I have searched to a good degree on stack overflow etc to try find an answer to my question. I have so far been unable to find any solution that works for my specific problem.
Up until the 5th of February, When I ran the command:
.\gradlew test
The command would complete and the build would be successful. Today (7th), I pulled changes from my teams remote repo. When I ran the command I would get the below output:
:app:preBuild UP-TO-DATE

:app:compileDebugUnitTestJavaWithJavac FAILED
BUILD FAILED
Total time: 5.804 secs
I created a new branch to see if I could figure out what commit was causing the issue, however, when I checked out a commit that I knew for certain did not contain issues (the commit I had previously been at) and attempted to run the command I would get similar output.
Similarly I used to be able to simply right click on my test file and select "Run whateverTest.java" and the test would run.
Now when I attempt the same thing I get the following output:
!!! JUnit version 3.8 or later expected:
java.lang.RuntimeException: Stub!

Process finished with exit code -3
Now I must select the file and select "Run..." from the run tile. This will run my tests successfully.
I have attempted the ususal build, clean restart computer etc. I have also attempted to create a JAVA_HOME and ANDROID_JAVA_HOME environment variable (under recommendation of similar questions).
Since that time the only thing that sticks out to me is that there was a java update. I suspect this may be the cause but I am not certain.
I would appreciate any help and I can provide any more details that are required.
Thanks.
UPDATE
For more context here is more of the output from .\gradlew test
* What went wrong:
Execution failed for task ':app:compileDebugUnitTestJavaWithJavac'.
> Could not find tools.jar
Hopefully this gives better context.
SOLVED
Problem was solved by uninstalling both Java and Android Studio and then reinstalling them.
I believe there was a path hidden somewhere in Android Studio that I was unable to change that took a reinstall for me to be prompted to select.
