是否可以在Gradle中为JavaCompile启用-werror？

Question

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

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

导致生成完全失败（不是以正确的方式）：

失败：生成失败，出现异常。

*错误：任务“：app：compiledebugjava”执行失败。

是否不支持adding-werror？

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs << "-Xlint:all" << "-Werror"
        }
    }
}

结果将是下一个

....
:app:compileDebugJava
