java - SonarQube 5.1 分析因 StackOverflowError 失败

Question

我最近升级到最新的 SonarQube 5.1，但现在，我的 Maven 构建开始失败，我无法确定导致错误的文件。 maven项目是一个多模块项目。

• SonarQube 5.1 版
• 使用“mvn sonar:sonar”执行的 Maven 目标(使用 2.6 版并正确分析了一些项目)

maven 构建完成并出现以下错误:

调试错误原因有什么想法吗？我已经尝试使用 -debug 标志。

Answer 1

问题已解决。

我最终设置了一个本地实例并使用调试器运行 maven 插件，这允许我在异常处设置一个断点。我发现我们有一个测试用例(文件)，它有一个由数百个字符串定义的字段。这个文件已经很久没有编辑了，所以我猜整体堆栈大小已经从 4.x 变成了 5.x。测试很丑陋，因此我在这种情况下的解决方案是重构它。我想另一种解决方案是增加 java 堆栈大小，但我没有尝试过。
