Error:Execution failed for task ':app:transformClassesWithDexForDebug"

3个错误non-zero exit value 1； non-zero exit value 2； non-zero exit value 3

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.

> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'F:Program Files (x86)Javajdk1.8.0_31injava.exe'' finished with non-zero exit value 1

这个是因为依赖包重复了 ，如图。app中实现了对easeUI的依赖，但是app和easeUI都添加了对这个包的依赖。所以就报这个错误，修改之后再报，就clean，rebuild一下

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'F:Program Files (x86)Javajdk1.8.0_31injava.exe'' finished withnon-zero exit value 2

这个错误是注释掉app中的v4包之后出现的。解决方法 clean ,rebuild一下工程，就解决了。要是还解决不了，就重启一下。

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.

这个错误就在app.bulid里面加上这句，再rebuild ,之后再运行就行了。4g可以看电脑配置修改（2g,3g,6g,8g）。

 

dexOptions {
    javaMaxHeapSize "4g"
}

如图：
