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)[Java](http://lib.csdn.net/base/javase)\jdk1.8.0_31\bin\java.exe'' finished with non-zero exit value 1

这个是因为依赖包重复了 （像v4和nineoldandroids），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)\Java\jdk1.8.0_31\bin\java.exe'' finished withnon-zero exit value 2

这个错误在app的build.gradle里面添加下面这句就好了。

android { defaultConfig { ... multiDexEnabled **true**** **}}

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)\Java\jdk1.8.0_31\bin\java.exe'' finished withnon-zero exit value 3

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：
