引入之前在eclipse下開發的專案到AndroidStudio 遇到了如下錯誤：

Error:Execution failed for task ':guanXiang:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_79\bin\java.exe'' finished with non-zero exit value 2
 

dexOptions {
    javaMaxHeapSize "4g"
    
}

defaultConfig {
     multiDexEnabled  true
}

加入後還是有問題，發現這個問題的本質還是相同jar或者檔案導致的衝突，根據提示發現有個跟友盟分享的類衝突了

Error:Execution failed for task ':guanXiang:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/tencent/mm/sdk/a/a$a.class

    }

成功解決！
