  2. Reference to findViewById() is ambiguous when running unit test

Reference to findViewById() is ambiguous when running unit test

问题


this morning I updated Android Studio to the latest stable 3.x build, together with support libraries, buildTools version and the new gradle plugin

I managed to get everything work (with a lot of pain dure to the new gradle plugin), but now I have a problem which I can't really understand:

The project compiles, and the unit tests of PROJECT1 and PROJECT2 run fine, but when I try to run unit tests of main project, I get this error:

Error:(40, 30) error: reference to findViewById is ambiguous both method findViewById(int) in Activity and method findViewById(int) in AppCompatActivity match where T is a type-variable: T extends View declared in method findViewById(int)

This happens only when I try to run the tests, the app (where I use a lot of calls to findViewById() ) is working fine.

Where should I look for to fix the issue?

buildToolsVersion: 27.0.1
support repository version: 27.0.2
targetSdkVersion: 27
compileSdkVersion: 27
minSdkVersion: 19

This is a piece of code where the issue happens

@Before
    public void setUp() {
        super.setUp();

        ChangePasswordActivity mActivity = Robolectric.setupActivity(ChangePasswordActivity.class);
        mPasswordBox = mActivity.findViewById(R.id.general_password_vPasswordBox);
        mBtnNext = mActivity.findViewById(R.id.general_password_btnNext);

    }

I can build and run the project, but when I run tests I get this kind of error in all the test classes

Here my gradle files, I have a main project which depends on library projects

I am afraid that the problem is somehow related to the new dependency configurations , but I'm not sure about that, is just a smell. Hope that the gradle file can help you to help me :)
