[Android-tools-devel] Does this thing actually work?

[殷啟聰 | Kai-Chung Yan]

I was recommending you use the upstream Gradle and Gradle plugin.

First, use `gradlew` instead of `gradle` so you can use the upstream Gradle downloaded from the internet. Then, use the Maven repository from JCenter and Google instead of `/usr/share/maven-repo`. Finally, use the latest version of the Gradle plugin (e.g. `classpath 'com.android.tools.build:gradle:3.4.2'`). You can get more info at <https://developer.android.com/studio/releases/gradle-plugin>.

My copy of the jar does not contain javax/xml/bind, though it does have several folders within javax/xml. I guess that means my copy of the jar is older.
