Android: Compile with -Xlint:deprecation

[GitToTheHub]

Hi,

when I build a plain Android Cordova app without any plugins on the latest master, i get some warnings:

> Task :CordovaLib:compileDebugJavaWithJavac
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

I want to examine, what these problems are by compiling it with -Xlint:deprecation, but I don't have a clue how I can do it :)

Regards,

Manuel

In the projects build.gradle file (not to be confused with the module/app's build.gradle) the following will enable deprecation prints:

allprojects {
    subprojects {
        afterEvaluate {
            tasks.withType(JavaCompile).tap {
                configureEach {
                    options.compilerArgs += "-Xlint:deprecation"
                }
            }
        }
    }
}

Not sure on the best way to inject this into the cordova project, but I feel like this should be an option that can be enabled, maybe via a preference.

Thanks, that worked :)

Maybe in cordova-android@15, we can just flip a preference flag on: apache/cordova-android#1822 ;)

Cool thanks for directly implementing and documenting it :) Maybe it would be good to also note in the documentation, that it sets "-Xlint:deprecation" for compiling? I'm noting this, because when a developer sees:

> Task :CordovaLib:compileDebugJavaWithJavac
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

He could google "cordova -Xlint:deprecation" and he would find the preference flag.
