Testing Gradle can'；t在Windows 10上运行我的项目测试（读取executionHistory.lock时出错；多进程锁定文件）

我有一个大型Java桌面（非Android）项目，其中包含许多子模块，我最近开始尝试在Windows 10上构建和运行它。（通常我在MacOS上运行构建。）

我们在尝试运行测试时总是会出错；这个错误发生在Windows 10机器上，我和项目中的其他开发人员都是从新签出代码开始的

以下是错误：

2020-11-09T18:21:51.995-0800[INFO][org.gradle.internal.snapshot.impl.DirectorySnapshotter]无法读取文件路径“C:\Users\Me\myproject\.gradle\6.6.1\executionHistory\executionHistory.lock”。

--debug

日志中的错误之后紧接着是以下堆栈跟踪；我不知道是否相关，但每次出现上述错误后都会出现：

我还看到有关读取其他文件的错误：

2020-11-09T18:21:51.998-0800[INFO][org.gradle.internal.snapshot.impl.DirectorySnapshotter]无法读取文件路径“C:\Users\Me\myproject\.gradle\6.6.1\fileContent\fileContent.lock”。

（上面是关于MD5散列和锁定文件一部分的某些其他进程的一对相同的异常）

2020-11-09T18:21:52.029-0800[INFO][org.gradle.internal.snapshot.impl.DirectorySnapshotter]无法读取文件路径“C:\Users\Me\myproject\.gradle\6.6.1\fileHashes\fileHashes.lock”。

（相同）

请注意，整个项目在Windows 10上正确构建和运行。这只是运行测试时出现的问题。但是我很想解决这个问题，这样Windows开发者就可以运行它们了

我试过以下方法，但都不奏效

• 在不同机器上重新检查项目
• 删除项目的

  .gradle

  文件夹并清理重建
• 牺牲一只非常小的山羊

起初我认为错误可能是由一些失败的测试（我有一些集成测试没有在Windows 10上运行）引起的，但在禁用这些测试后，我（和我的队友）仍然会收到错误

请注意，在Docker容器内构建时，提出了一个非常类似的问题：

但是，我们不是在Docker容器中构建，上面的解决方案对我们不起作用。我正在Mac OS Catalina主机上构建一个VirtualBox Windows 10来宾虚拟机，我的队友也看到了这个错误，他正在构建一台Windows 10笔记本电脑。这里没有码头工人

我欢迎关于如何帮助进一步诊断这个问题的想法。请注意，由于项目的规模和古老性，试图将其缩小到一个小样本复制案例是不切实际的。

我也遇到了同样的问题，并用

这里的问题是目标目录包含.gradle目录，该目录由初始gradle进程使用，因此在Windows中被锁定。然后守护进程尝试散列lockfile，因为它散列目标目录中的所有文件以检查任务是否是最新的，但由于它是一个lockfile，因此任何其他进程都无法访问它。 解决方案是将任务的输出目录设置为一个文件夹，在该文件夹中它不能干扰任何锁定的文件

总而言之，您可以使用如下标志运行gradlew来解决您的问题：

--project-cache-dir=../cache
