gradle和robolectric升级后的资源$ NotFoundException google_play_services_version

Question

I am attempting to update a project to Gradle 3.0.1 / gradle wrapper 4.1. Robolectric tests that used to work are now failing when run with ./gradlew testDebugUnitTest :

android.content.res.Resources$NotFoundException: org.odk.collect.android:integer/google_play_services_version
    at org.robolectric.android.internal.ParallelUniverse.setUpApplicationState(ParallelUniverse.java:72)
    at org.robolectric.RobolectricTestRunner.beforeTest(RobolectricTestRunner.java:319)
    at org.robolectric.internal.SandboxTestRunner$2.evaluate(SandboxTestRunner.java:220)
    at org.robolectric.internal.SandboxTestRunner.runChild(SandboxTestRunner.java:108)
    at org.robolectric.internal.SandboxTestRunner.runChild(SandboxTestRunner.java:35)

• com.android.tools.build:gradle:3.0.1
• org.robolectric.robolectric:3.5.1
• build tools 26.0.2
• gradle wrapper 4.1

This is an open source project -- the updated configuration is available here .

It doesn't seem related but just in case -- we also started seeing pmd and lint errors that we didn't before. Those configs or versions haven't changed.

I have found the following possibly related issues:

• https://github.com/robolectric/robolectric/issues/3333
• https://github.com/robolectric/robolectric/issues/3374
• Reference to findViewById() is ambiguous when running unit test

None of the suggestions on those posts have helped so far. I've read the release notes for gradle and robolectric and am not seeing any hints. Any idea which tool is likely to be causing the problem? Any thing else I can try?

Answer 1

Removing a @Config(constants = BuildConfig.class, sdk = 21, manifest = "src/main/AndroidManifest.xml", packageName = "org.odk.collect") and adding in testOptions.unitTests.includeAndroidResources true did the trick. Full diff here .
