android: gradle: how to copy a file? Issue to set a file readable, or to read it

Question

I am blocked by a file reading in Gradle.

I try to set files readable this way in gradle:

task readAccess(type: Exec, description: 'set the google-services.json readable.') {
     //--> check can read? --> can't read
    if (new File('src/google-services.json').canRead()){
        println 'readAccess > can read'
    } else {
        println 'readAccess > cant read'
    }
    //--> set readable. --> can't set readable
    if (new File('src/google-services.json').setReadable(true,false)) {
        println 'readAccess > access read modified'
    } else {
        println 'readAccess > access read not modified'
    }
    //--> check can read? --> can't read
    if (new File('src/google-services.json').canRead()){
        println 'readAccess > can read'
    } else {
        println 'readAccess > cant read'
    }
}

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn gcmReadAccess
}

PS: the file access is set to read & write by everyone, in the file system.
