声纳maven插件构建错误,SonarQube版本:null

Question

我的jenkins构建刚刚开始失败并显示以下消息:

这是怎么回事？

Answer 1

通过将自动选择的最新(2.7)版本降级到旧版本(2.4),将此代码添加到我的插件部分来解决 pom.xml

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>sonar-maven-plugin</artifactId>
    <version>2.4</version>
  </plugin>

Answer 2

对于那些对"为什么？"感兴趣的人 ,我已经做了一些挖掘,似乎正在发生的事情是这样的:

• RunnerBootstrapper尝试检查版本是否为5.2+:

• 首先,从EmbeddedRunner中创建的启动器中检索 serverVersion ,

• 使用IsolatedLauncher创建代理的实现类BatchIsolatedLauncher

• 它试图读取sq-version.txt包含该版本的资源文件.

这个sq-version.txt文件位于org.codehaus.sonar:sonar-plugin-api中,但是在sonar-maven-plugin中不包含这个依赖(甚至是传递).所有引用声纳的都是org.sonarsource.sonar-runner:sonar-runner-api.

他们似乎更改了版本txt文件的位置和名称,但没有更新所有代码.您可以通过手动向插件类路径添加sq-version.txt内容5.2(无新行)(可能通过更新插件jar),或者添加对sonar-plugin-api的依赖,但这些都是黑客.

该声纳Maven的插件2.6使用声纳亚军2.4,它是2.5截然不同的是声纳Maven的插件2.7用途(在的groupId声纳亚军已经改变域从org.codehaus.sonar.runner到org.sonarsource.sonar-runner),所以最好坚持到第2版. 6插件直到他们平滑过渡并发布了更多版本.

Answer 3

传递SonarQube服务器版本的方式maven-sonar-plugin在v2.7中已经改变,因为它现在使用了sonar-runner 2.5.

与SonarQube实例<4.3一起使用时确实存在一个错误,为此我开了票:https://jira.sonarsource.com/browse/MSONAR-131

请注意,不再主动支持SQ <4.5(当前LTS),并且sonar-maven-plugin由于新接口所暴露,因此无法保证在其他方面不会与它们不兼容sonar-runner 2.5.

对于这些情况,最好将maven插件版本锁定为2.6,如已建议的那样.
