我的第一个问题，如有不便，请见谅。我在使用 Jenkins+SonarQube 时遇到了一个问题。我在 Jenkins 发布步骤中添加了“执行 SonarQube 扫描仪”，确定它会正常工作，因为其他项目进展顺利。但是今天这个过程失败了几次，我检查了控制台输出发现停留在一个文件上的分析将无法继续，就像：

这会导致“java.lang.OutOfMemoryError：GC 开销限制超出”，声纳分析将失败，有什么帮助吗？非常感谢。
顺便说一句，java文件是名为“BaseCmd.java”的Apache Cloudstack文件之一，所以原始文件应该没问题。

如果您在 google 搜索框中键入“SonarQube”，然后单击列表中的 VERY FIRST 项，然后单击“需要设置分析”，然后您会到达底部有以下内容的页面：

常问问题

Q. java.lang.OutOfMemoryError 分析错误：超出 GC 开销限制。我该怎么办？

A. 这意味着您的项目太大或太复杂，扫描仪无法使用默认内存分配进行分析。要解决此问题，您需要为运行分析的进程分配更大的堆（使用 -Xmx[此处的数值]）。某些 CI 引擎可能会为您提供输入以指定必要的值，例如，如果您在 Jenkins 作业中使用 Maven 构建步骤来运行分析。否则，使用 Java 选项设置更高的值。请注意，此处省略了设置 Java 选项的详细信息，因为它们因环境而异。

没有找出我被卡住的原因:(。确定文件没问题，所以我最终将此文件添加到忽略列表中。过程顺利。
