Running Robolectric SNAPSHOT

1. Clone the robolectric repository: git clone --recurse-submodules https://github.com/robolectric/robolectric.
2. Check out the branch/commit that you want to run.
3. Run ./gradlew publishMavenJavaPublicationToMavenLocal in the Robolectric root directory. It is also faster to run SKIP_JAVADOC=true ./gradlew publishMavenJavaPublicationToMavenLocal. If you can't run it on Ubuntu 20.04 with icu building problem, you can export CC=gcc and export CXX=g++ at your terminal before running this command to fix building problem temporarily.
4. Add mavenLocal() to your project's root project build.gradle:

   allprojects {
     repositories {
       mavenCentral()
       google()
       mavenLocal()
     }
   }

5. Update your project to use the SNAPSHOT version of Roblectric (4.8-SNAPSHOT at time of writing).

   dependencies {
       ...
       testImplementation 'org.robolectric:robolectric:4.8-SNAPSHOT'
       ...
   }

6. Run your project's tests.
