Running Robolectric SNAPSHOT - robolectric/robolectric GitHub Wiki

Clone the robolectric repository: git clone https://github.com/robolectric/robolectric.
Check out the branch/commit that you want to run.
Run ./gradlew publishMavenJavaPublicationToMavenLocal in the Robolectric root directory. It is also faster to run SKIP_JAVADOC=true ./gradlew publishMavenJavaPublicationToMavenLocal.

Add mavenLocal() to your project's root project build.gradle:

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

Update your project to use the SNAPSHOT version of Roblectric (4.10-SNAPSHOT at time of writing).

dependencies {
    ...
    testImplementation 'org.robolectric:robolectric:4.10-SNAPSHOT'
    ...
}
