failOnVersionConflict has never been good for us. It is equivalent to
Maven dependencyConvergence which we discourage our users to use because
it is too tempermental and _creates_ version skew issues over time.
However, we had no real alternative for determining if our deps would be
misinterpeted by Maven.
failOnVersionConflict has been a constant drain and makes it really hard
to do seemingly-trivial upgrades. As evidenced by protobuf/build.gradle
in this change, it also caused _us_ to introduce a version downgrade.
This introduces our own custom requireUpperBoundDeps implementation so
that we can get back to simple dependency upgrades _and_ increase our
confidence in a consistent dependency tree.
Bumps target SDK version of grpc-android, grpc-cronet, grpc-android-interop-testing to API 29. Major related changes are:
- Migrated android.support to androidx, which is required for Android Q.
- android.net.NetworkInfo is deprecated in SDK 29, suppressed compiler warnings as it is needed for supporting old Android versions.
- Robolectric requires Java 9+ for Android 29, which causes unit tests in grpc-cronet fail. Added annotation to emulate Android 28 for grpc-cronet's test.
- Upgraded Android dependencies accordingly in android-interop-testing.
- Use gradle configuration `api` for dependencies that are part of grpc public api signatures.
- Replace deprecated gradle configurations `compile`, `testCompile`, `runtime` and `testRuntime`.
- With minimal change in dependencies: If we need dep X and Y to compile our code, and if X transitively depends on Y, then our build would still pass even if we only include X as `compile`/`implementation` dependency for our project. Ideally we should include both X and Y explicitly as `implementation` dependency for our project, but in this PR we don't add the missing Y if it is previously missing.
* Added publish configurations in build file.
* Changed cronet dependency to cronet-api for implementation, only use full cronet implementation provider for testing.
* Set minSdkVersion to 16 as cronet dependency requires that.
* Added errorprone plugin.
This PR adds an automatic gradle format checker and reformats all the *.gradle files. After this, new changes to *.gradle files will fail to build if not in good format, just like checkStyle failure.
