Windows上的Gradle构建错误“无法为文件创建MD5哈希" [英] Gradle build error on Windows "Failed to create MD5 hash for file"

问题描述

我正在现有项目上运行gradle构建，并且在下面遇到此错误.

I am running a gradle build on a existing project and I run into this error below.

• 出了什么问题:在最新检查期间无法捕获任务'someTask'属性'destinationDir'的输出文件快照.

• What went wrong: Failed to capture snapshot of output files for task 'someTask' property 'destinationDir' during up-to-date check.

无法为文件'my_project_dir \ .gradle \ 3.5 \ fileContent \ fileContent.lock'创建MD5哈希.

Failed to create MD5 hash for file 'my_project_dir\.gradle\3.5\fileContent\fileContent.lock'.

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.

Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

我使用--stacktrace选项运行，它抱怨文件被锁定在project_dir \ 3.5 \ fileContent中，但是无法弄清楚问题出在哪里，任何指针都值得赞赏.

I ran with --stacktrace option, it complains about a file being locked in project_dir\3.5\fileContent, but not able to figure out what the issue is, any pointers are appreciated.

推荐答案

此处的问题是目标目录包含.gradle目录，该目录由初始gradle进程使用，因此已在Windows中锁定.然后，守护程序尝试对锁定文件进行哈希处理，因为它会哈希目标目录中的所有文件以检查任务是否最新，但是由于它是一个锁定文件，因此无法由任何其他进程访问.

The issue here is that the destination directory contains the .gradle directory, which is used by the initial gradle process and is thus locked in Windows. Then the daemon tries to hash the lockfile, because it hashes all files in the destination dir to check if the task is up to date, but since it is a lockfile, it can't be accessed by any other process.

解决方案是将任务的输出目录设置为不会干扰任何锁定文件的文件夹.

The solution is to set the output directory of the task to a folder where it can't interfere with any locked files.
