我将 Maven 3.2.1 和 SonarQube 4.5 与 Checkstyle 5.6 结合使用。执行中

mvn sonar:sonar

对于某些项目工作正常，但其他项目失败并显示“无法执行 Checkstyle:无法读取 ... checkstyle.xml - 无法解析配置流 - 处理指令目标匹配”[xX][mM][lL] “不被允许”。这是输出:

其实生成的checkstyle.xml是错误的，因为它包含两次“<><>

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE module PUBLIC "-//Puppy Crawl//DTD Check Configuration 1.2//EN" "http://www.puppycrawl.com/dtds/configuration_1_2.dtd"><!-- Generated by Sonar --><module name="Checker"><?xml version="1.0" encoding="UTF-8"?>

...

为了分析，我上传了这个文件: - checkstyle.xml:https://dl.dropboxusercontent.com/u/54665247/checkstyle.xml

在谷歌搜索中我一无所获。 有人可以帮我解决这个问题吗？

最佳答案

我解决了我的问题。似乎旧的、迁移的数据导致了这个问题:我使用 Sonar 已经好几年了，从 3.1 版开始。每隔一段时间我就会升级到当前版本，从而迁移我现有的 Sonar MySql 数据库。最后一次升级是从 3.7.4 到 4.5。似乎最初导入的 checkstyle.xml(引用 http://www.puppycrawl.com/dtds/configuration_1_3.dtd)的 XML header 被添加到当前 XML header (引用“http://www.puppycrawl.com/dtds/configuration_1_2.dtd”)，但没有被替换，导致两个 XML header ，因此 XML 无效。

我通过删除 SonarQube 中受影响的项目解决了我的问题。此操作的代价是我丢失了过去几年的所有历史数据。

关于java - sonar-maven-plugin fails because of invalid checkstyle.xml (The processing instruction target matching "[xX][mM][lL]"is not allowed)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26339005/
