Steps to reproduce Create new project on Business Central (I named mine "junit-fails") Add a new "Data Object" asset. (I named mine MyClass ). Git clone the project from Guvnor to a different local folder. Import local cloned project to any IDE (I used RedHat Code Ready). Create a JUnit test class within src/test/java in the same Java package, with a test method that uses the "Data Object" meaningfully in some manner. (I instantiated MyClass and performed a simple assertEquals() on a property). Commit the JUnit class. Reimport the project back to Business Central, so that the JUnit class shows. Attempt to build/deploy through Business Central using "Build" or "Deploy" buttons.
