How to recompile with -Xlint:deprecation

Question

I don\'t use Android Studio but I build everything from the command line using build.gradle. I generate a Lint report like this:

./gradlew lint
         


        

Answer 1

This is an accepted answer but solved this with Gradle Java plugin as below.
Add java plugin to build.gradle file if not added already.

plugins {
    // Apply the java plugin to add support for Java
    id "java"
}

Then add task compileJava and/or compileTestJava based on your need to check deprecations for only java main source code or java test source code.
You can add various compile options as listed here

compileTestJava {
   // options.incremental = true
   // options.fork = true
   // options.failOnError = false
    options.compilerArgs.add("-Xlint:deprecation")
}

Also, we can specify for the main and test sourcecode project as

tasks.withType(JavaCompile) {
    options.compilerArgs.add("-Xlint:deprecation")
}
