library - ¿Cómo suprimo las advertencias al compilar una biblioteca de Android con gradle?

com.android.support:design 26

Question

En mi solicitud, tengo una biblioteca desarrollada por un tercero que, desafortunadamente, contiene bastantes advertencias sobre pelusas y javac. Me gustaría ignorar estos dos tipos de advertencias ya que nuestro equipo no puede corregirlas y están contaminando nuestros registros de compilación. He intentado agregar lo siguiente al archivo build.gradle de las bibliotecas:

En el bloque android

lintOptions {
    ignoreWarnings = true
}

También agregué lo siguiente al final del archivo build.gradle:

afterEvaluate {
    tasks.withType(JavaCompile) {
         it.options.compilerArgs << "-Xlint:none" << "-nowarn"
    }
}

Desafortunadamente, siempre que se ejecuta ": compileDebugJavaWithJavac", aún se emiten las advertencias de este proyecto. ¿Qué estoy haciendo mal?

EDITAR Aquí está el archivo build.gradle en su totalidad

apply plugin: ''com.android.library''

dependencies {
    compile fileTree(dir: ''libs'', include: ''*.jar'')
}

android {
    compileSdkVersion 21
    buildToolsVersion "23.0.2"

    lintOptions {
       abortOnError false        // true by default
       checkAllWarnings false
       checkReleaseBuilds false
       ignoreWarnings true       // false by default
       quiet true                // false by default
    }

    sourceSets {
        main {
            manifest.srcFile ''AndroidManifest.xml''
            java.srcDirs = [''src'']
            resources.srcDirs = [''src'']
            aidl.srcDirs = [''src'']
            renderscript.srcDirs = [''src'']
            res.srcDirs = [''res'']
            assets.srcDirs = [''assets'']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot(''tests'')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot(''build-types/debug'')
        release.setRoot(''build-types/release'')
    }
}

afterEvaluate {
    tasks.withType(JavaCompile) {
         it.options.compilerArgs << "-Xlint:none" << "-nowarn"
    }
}

El siguiente es un ejemplo de las advertencias que recibo que quiero eliminar:

advertencia: [sin marcar] llamada sin marcar a isAssignableFrom (Clase) como miembro del tipo de clase sin formato if (type.isAssignableFrom (throwables [i] .getClass ()))

These options are non-standard and subject to change without notice.

Desactive todas las advertencias:

// Put this in ''root'' `build.gradle`, in allprojects or subprojects
tasks.withType(JavaCompile) {
     // Try to turn them all off automatically
     options.compilerArgs << ''-Xlint:none''
     options.compilerArgs << ''-nowarn'' // same as ''-Xlint:none''
