Question

我在其中一个项目中遇到此错误。

失败：构建因例外而失败。




出了什么问题：

任务＆＃39;：app：transformClassesWithDesugarForDevServerDebug＆＃39;执行失败。   com.android.build.api.transform.TransformException：java.io.IOException：无法删除路径＆＃39; D：\ Android \ Projects \ uralenergo \ app \ build \ intermediates \ transforms \ desugar \ devServer \ debug \ 1的.jar＆＃39;



尝试：
      使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获取更多日志输出。使用--scan运行以获得全面的见解。

在9s内建立失败

我经常参与这个项目，当我尝试在手机上运行我的应用程序时，我已经厌倦了40％的情况下看到此错误。

如果我执行Rebuild Project，则错误消失并编译应用程序。但是在构建应用程序2-3次之后，再次出现此错误。

项目非常庞大，我不能在Rebuild Project上浪费时间。我试图手动删除此文件夹。但它没有帮助我。

Answer 1

发生这种情况是由于多种原因，例如，当您升级操作系统或更改项目的路径或再次下载studio时，需要删除build文件夹中的先前文件。因此，在这种情况下，请以<>>以管理员身份运行 Android Studio 。

然后右键单击studio项目中的build文件夹，然后单击在资源管理器中显示。 现在删除构建文件夹。如果需要管理员权限，请单击复选框并删除它。现在重建项目并运行该项目。

Answer 2

发生此错误是因为先前构建的某些进程未结束，现在正在锁定该文件/文件夹。

您可以使用Windows Process Explorer检查哪个进程正在锁定该文件夹/文件。然后，您只需要杀死该进程（Windows任务管理器）。

Link for Windows Process Explorer

如果您不想使用该Process Explorer，可以尝试关闭Android Studio，此过程也可能完成。或者，您可以重新启动计算机以终止所有进程。

我经常使用Windows Process Explorer。这样，我可以在不重新启动PC的情况下找到并终止任务...

Answer 3

这种情况一直发生在我身上。别担心。这是一个简单的解决方案。只需转到该文件夹（\ debug），然后将其删除即可。然后清理并重建您的项目。

Answer 4

谢谢大家的回答。我通过删除Java 9并安装了Java 8来解决了这个问题。当我安装Java 10时，问题并没有消失。我认为我们需要等待Android Studio的更新。
