Java 生成失败：等待了30秒等待com.google.common.util.concurrent。SettableFuture@4f4028ea[状态=待定]

为什么在Android studio上运行应用程序时总是失败？ 我试图找到一个解决办法，但没有答案

错误如下：

我该怎么办？ 请详细解释

谢谢你

在我的例子中，android studio将我的另一个项目中的应用程序图标混合到了我当前的项目中。我删除了迁移的应用程序图标，错误消失了

如果有人遇到此错误，请确保您也尝试此解决方案。即使在尝试了以上所有的解决方案之后，要找出真正的问题还是让人头疼

我终于通过重启windows解决了这个问题。希望这能帮助一些人。

对我来说类似的问题，最终在我尝试禁用Windows防火墙时得到了修复。

看起来守护进程无法启动-可能是防病毒软件阻止了aapt2可执行文件？
