SonarQube 后台任务因多个具有相同键的条目而失败

Question

我知道这是与SonarQube background tasks failing with IllegalArgumentException for Java 非常相似的问题，但就我而言，我不知道问题到底出在哪里。 这是我的日志：

问题是我只能看到java.lang.IllegalArgumentException: Multiple entries with same key: scala=Scala and scala=Scala，所以我不确定问题出在哪里。

之前已经有一个项目，我为这两个项目使用了相同的属性。是否有可能因为我为他们两个都设置了sonar.projectKey=org.codehaus.sonar:javascript-sonar-runner-lcov 而发生了这个问题？或者这不是错误消息所指的关键？如果是，那我应该把什么写成sonar.projectKey？

Answer 1

您正在使用向 SonarQube 声明完全相同的语言 (scala) 的 2 个插件（scalastyle 和 scoverage）。这不是插件的行为方式：应该有一个插件声明该语言（理想情况下命名为“sonar-scala-plugin”）和其他将引用该语言的辅助插件（但不声明它）。

• SONAR-7318 已在 SonarQube 上创建，以确保更早地注意到这一点。
• 编辑：已创建scala key duplicated #31 以在插件方面解决此问题。

一旦这些插件的开发人员就哪个插件声明了语言以及其他插件引用了它达成一致意见，您的问题就应该得到解决。

Answer 2

我遇到了同样的问题，我做了以下事情：

1. 我制作了一个 sonar-scala-plugin 来定义 scala 语言并将其添加到我的 sonaqube。
2. 我从 scalastyle 插件：https://github.com/NCR-CoDE/sonar-scalastyle 和 scoverage 插件：https://github.com/RadoBuransky/sonar-scoverage-plugin 下载了源代码

3. 然后我重构了代码，在扩展声纳插件的类中，我删除了定义语言的类： 我的 ScalastylePlugin 如下所示：

   覆盖 def getExtensions: java.util.List[Class[_ <: extension listbuffer classof>

4. 我为声纳覆盖插件做了同样的事情。在扩展 SonarPlugin 的类中，我删除了 classOf[Scala];

5. 然后我构建了所有插件并将插件 jar 文件添加到 sonarqube。
