[Feature Request] - Make all warnings errors

[C-Otto]

I'd like to fail my build if Error Prone finds a warning in my code. Then, I'm forced to fix the code, or suppress the warning. I'm aware of false positives, and I'm happy to take the risk.

Please have a look at #614 for more information (feel free to re-open and continue there).

Do you use -Werror? Works great for me.

Thanks, didn't know about that (see Twitter).

tasks.withType(JavaCompile) {
    options.compilerArgs << "-Werror"
}

or

compileJava {
    options.compilerArgs << "-Werror"
}
