maven - Jenkins & Sonar : [ERROR] Unable to evict preview database:/batch_bootstrap/evict? 项目=68

Question

我正在尝试将 Sonar 与 Jenkins 集成。一切都已设置并成功运行。当我在 Jenkins 中构建项目时，它显示 ANALYSIS SUCCESSFUL 但构建失败并出现以下错误。

[INFO] [15:59:54.852] ANALYSIS SUCCESSFUL, you can browse http://mysonarurl.com/sonar/dashboard/index/myproject

在我收到此错误之前，它显示的是“java heap space”错误，但在将 -Xmx1024m 添加到 MAVEN_OPTS 后已解决。

如能提供有关此错误的任何帮助，我们将不胜感激。提前致谢。

我们在同一台 (Ubuntu) 机器上运行 Jenkins、Sonar 和 PostgreSQL 服务器，在从 Sonar 3.3 升级到 SonarQube 4.1 并对一个包含超过 890k LOC 的大项目进行分析后遇到了同样的问题。

首先我们得到了您提到的 OutOfMemmoryException，我们通过将 -Xmx 设置为 2048m 来解决它。解决内存问题后的第一次运行成功，但随后的所有运行都失败了

[ERROR] Unable to evict preview database: /batch_bootstrap/evict?... .

一段时间后，我们发现 6 个构建中有一个失败并出现以下异常:

java.io.FileNotFoundException: /some/path/someFile.java (Too many open files).

我们之前没有在任何 Sonar 或 Jenkins 日志中看到过这个异常。所以我们将打开文件限制从 1024(ubuntu 上的默认值)更改为 4096 并重新启动 Jenkins、Sonar 和 PostgreSQL 服务器。从那时起，所有构建都通过了。
