Robolectric 3.8 java.util.zip.ZipException

Question

I'm trying to upgrade my android project to sdk 27 and so I tried to upgraded robolectric to 3.8. Now I'm hanging on that error when I try to run my tests:

java.lang.RuntimeException: java.util.zip.ZipException: error in opening zip file

I think the interesting part of my gradle looks like that:

android {
  compileSdkVersion 27
  buildToolsVersion '27.0.3'
  defaultConfig {
    minSdkVersion 21
    targetSdkVersion 27
  }
}

dependencies {
  testImplementation 'org.robolectric:robolectric:3.8'
}

I already tried to clean my dependencies and deleting my gradle wrapper. I appreciate every tip you can give me, ty. If you need more information to be able helping me just ask for it.

Answer 1

Delete the .gradle directories in both your home directory and in your project's root directory and try building again.(from:Error when I try to generate a libgdx projet)

Answer 2

Delete the cache files in your maven cache. eg. my directory ~/.m2/repository/org/robolectric/android-all/8.1.0-robolectric-4611349
