Steps to reproduce:

1. Create module (for example: testtools) with jar files. Example of content of module build.gralde file:
```
configurations.maybeCreate("default")
artifacts.add("default", file('byte-buddy-1.6.14.jar'))
artifacts.add("default", file('byte-buddy-agent-1.6.14.jar'))
artifacts.add("default", file('cglib-nodep-2.2.2.jar'))
artifacts.add("default", file('hamcrest-core-1.3.jar'))
artifacts.add("default", file('javassist-3.21.0-GA.jar'))
artifacts.add("default", file('mockito-core-2.8.9.jar'))
artifacts.add("default", file('objenesis-2.5.jar'))
artifacts.add("default", file('powermock-mockito2-1.7.1-full.jar'))
```

2. Add dependency to application module like:
```
testImplementation project(':testtools')
```

Actual result:
You cannot import classes from added jar libraries inside test clases

Expected result:
Classes from added jar files can be imported.

Other notes:
If I add files jar files through next code: `testImplementation fileTree(include: ['*.jar'], dir: 'testLibsFolder')` then they works fine. Also in Android Studio 3.1.4 with gradle 3.4 adding dependency from module works fine.
