3個錯誤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\jdk1.8.0_31\bin\java.exe'' finished with non-zero exit value 1

這個是由於依賴包重複了 （像v4和v7），如圖。app中實現了對v7的依賴，可是app和v7都添加了對v4包的依賴。因此就報這個錯誤，修改以後再報，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

這個錯誤在app的build.gradle裏面添加下面這句就行了。

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

這個錯誤就在app.bulid裏面加上這句，再rebuild ,以後再運行就好了。4g能夠看電腦配置修改（2g,3g,6g,8g）。

android {
    ****
    dexOptions {
    javaMaxHeapSize "4g"
    }
}
