This version works around a warning about DuplicateStrategy in Gradle 6
that will be an error in Gradle 7 caused by [a bug in the plugin][1].
Bumping the version makes a clean build with `--warning-mode all` (at
least if skipping Android and codegen).
[1]: https://github.com/google/protobuf-gradle-plugin/issues/470
Updated protobuf gradle plugin version to 0.8.13. Fixed Android Kokoro's memory issue by forcing to use a new Gradle daemon for building the previous commit.
This resolves#5523
While bumping `com.android.tools.build:gradle:3.1.2` to `3.3.0`, some other plugins/artifacts/maven repo/buildscripts have to be updated:
- gradle (wrapper) need to upgrade to 4.10.x
- protobuf gradle plugin need to bump a version compatible with gradle version.
- need add `google()` and `jcenter()` repos for android (otherwise `com.android.tools.build:aapt2:3.3.0x` and `trove4j` will not be found resp.)
- need to accept license for Android "build-tools;28.0.3" in kokoro env.
The version bump happened in some places already, but many references
were missed.
This fixes the following warning that shows up with newer versions of
Gradle:
> Using TaskInputs.file() with something that doesn't resolve to a File
> object has been deprecated and is scheduled to be removed in Gradle
> 5.0. Use TaskInputs.files() instead.
Updates include:
* Build file and dependency updates
* Correcting the gradle wrapper for the clientcache example
* Lint fixes (including making AsyncTask subclasses static)
* Dropping the m-prefix from member variables
* Fixing the code indentation
* Fixing and enabling proguard for the routeguide example.
