android studio导入jar 后产生的 gradle 错误

导入jar包后，gradle报错

Error:Execution failed for task ':app:preDexDebug'. 
com.android.ide.common.process.ProcessException: 

org.gradle.process.internal.ExecException: Process 'command 

'/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bin/java''

finished with non-zero exit value 3

处理办法（一）

"compile fileTree(dir: 'libs', include: ['*.jar'])"

to

"provided fileTree(dir: 'libs', include: ['*.jar'])".

It resolved my problem

处理办法（二） 这个我没有尝试过，可以作为参考

android {
    // Other stuffs
    dexOptions {
        javaMaxHeapSize "4g"
    }
}
