Local Development

Code Style

We use google-java-format to format Java files. You can either install the IntelliJ plugin or use a pre commit hook to automatically re-format files.

To add a pre commit hook:

• Build google-java-format jar following instructions from github page.
• Copy config/git-hooks/pre-commit.template to .git/hooks/pre-commit
• Make the script executable: chmod +x .git/hooks/pre-commit
• Replace <<PATH_TO_JAR>> in .git/hooks/pre-commit with the location of google-java-format jar.

Useful commands to get your dev environment up and running

Force rerun of okbuck

❯ ./gradlew okbuck -Dokbuck.wrapper=true --stacktrace

Build all targets/tests (this matches what CI does)

❯ ./buckw targets //... --type android_binary android_instrumentation_apk java_test groovy_test robolectric_test kotlin_test scala_test | xargs ./buckw build

Misc

• You should be able to open this in IntelliJ like a plain Gradle project.
• If you hit ErrorProne errors when building, just rebuild. This is due to a known flakiness issue in Rocker.
