在推送新代码时，在org.pitest：mutationCoverage目标期间，我的CI构建失败。我的补丁集没有任何源代码的更改（只是一个新的空提交），但是打印了以下错误：
16:49:26 [ERROR] Failed to execute goal org.pitest:pitest-maven:1.4.0:mutationCoverage (default) on project common-scheduler: Execution default of goal org.pitest:pitest-maven:1.4.0:mutationCoverage failed: Input byte array has wrong 4-byte ending unit -> [Help 1]

我为PiTest启用了详细日志记录，为maven启用了调试日志记录，但日志中没有任何内容。
也无法在线看到与此错误类似的东西。
插件配置为：
<plugin>
<groupId>org.pitest</groupId>
<artifactId>pitest-maven</artifactId>
<version>1.4.0</version>
<configuration>

我正在努力了解错误的出处，因为它似乎根本不与任何代码更改相关，但每个新补丁集都在发生。
最佳答案
在github上为PiTest提出了一个问题：
https://github.com/hcoles/pitest/issues/629
问题是损坏的历史记录文件。清理环境并再次运行以解决问题。
