python自定义规则的SonarQube ClassNotFoundException

Question

我已经配置了我的 SonarQube 服务器和我的 python 项目，以便进行各种分析...（很正常...）

我想添加一条规则，以确保我在所有 python 脚本文件的开头放置了许可证/版权文本。使用 sslr-python-toolkit-1.5 应用程序，我成功创建了规则 XPath，并且还在 SonarQube 服务器上创建并激活了规则。

但是，当我启动声纳分析时，我有一个堆栈跟踪：

1. 我尝试使用命令行自己启动声纳扫描仪

   /usr/bin/java -cp sslr-python-toolkit-1.5.jar:sonar-scanner-cli-2.8.jar -Dscanner.home=/opt/sonar-scanner -Dproject.home=/home/dev /workspaces/pepyt org.sonarsource.scanner.cli.Main

但结果相同....

1. 我已将两个 jar 解压缩到一个目录中，没有任何变化...
2. 经过一番搜索后，我发现了一些关于 SONAR_SCANNER_OPTS 环境变量的 sonar-java-libraries 的帖子...如果使用了未解决问题的环境变量（在声纳运行日志中可见），则事件...
3. 我把 sslr-python-toolkit-1.5.jar 库放到了我的 sonar 主目录的 lib 目录下，没有任何成功

我没办法了……

如何将 sslr python 库添加到我的声纳扫描器类路径中，以便使用我的自定义规则分析代码？

这是 SonarQube Python 插件中的bug。它将在下一个版本中修复。感谢您的反馈！
