希望有人可以提供帮助。
- 我们的项目是一个Eclipse插件项目
- 我们有一个 Jenkins 服务器
- 我们的项目使用 Maven 和 Tycho（用于插件项目）进行构建管理
- 我们安装了声纳服务器
- 我们使用 Jenkins Web-Config 将 Sonar 集成到 Jenkins
现在，如果我们不使用 Sonar，一切都会好起来的。但是如果我们打开它，Sonar 的 Maven Cobertura 插件会抛出错误。其他一切（就输出而言）都可以。
现在，据我了解，会发生以下情况：
- Jenkins 构建项目
- Sonar 使用其静态代码分析插件和指标（Findbugs、PMD、RFC 等）
- Sonar 启动 Cobertura 插件
- Cobertura 尝试再次构建项目
- Cobertura 没有成功构建它，因为它以不同的顺序构建它
- Cobertura 失败
詹金斯的一些输出摘录：

后来……建造顺序是先建造核心再进化，但进化似乎是Cobertura想要建造的第一件事……

我的猜测是声纳中的构建顺序不正确。但它会如何变得混乱（因为 Jenkins 以正确的顺序构建项目）？
为什么 Cobertura 会再次建造这个项目？Jenkins 已经构建了它，Cobertura 可以使用从那里编译的类......还是我误解了什么？
