嗨，我有一个android项目，当我想获取release.apk时，它会显示此错误，昨天我得到了版本，很好
错误：任务'：app：transformClassesWithDexForRelease'的执行失败。 com.android.build.api.transform.TransformException：com.android.ide.common.process.ProcessException：java.util.concurrent.ExecutionException：com.android.ide.common.process.ProcessException：执行Java进程时出错主类com.android.dx.command.Main带有参数{--dex --num-threads = 4 --multi-dex --main-dex-list D：\ android \ projects \ android-client \ app \ build \ intermediates \ multi-dex \ release \ maindexlist.txt-输出D：\ android \ projects \ android-client \ app \ build \ intermediates \ transforms \ dex \ release \ 0 --min-sdk-version 17 D：\ android \ projects \ android-client \ app \ build \ intermediates \ transforms \ jarMerging \ release \ 0.jar}
这是怎么一回事？
