java - Maven 依赖冲突：org.w3c.dom.ElementTraversal

Question

我有一个 Java 代码库，它使用 Maven 来解决依赖关系并在 CI 上运行测试。在最近的一批开发之后（大到难以识别重大更改），我的一些测试现在在通过带有NoClassDefFoundErrorfor 的Maven 运行时失败org.w3c.dom.ElementTraversal。当从我的 IDE (IntelliJ IDEA) 中运行时，相同的测试通过，因此可以安排类路径以满足所有依赖项。

我相信org.w3c.dom.ElementTraversal 存在于 xml-apis jar 1.4.01中（这是我所依赖的 - 请参阅下面的依赖树 - 就像我运行时在我的类路径中一样mvn dependency:build-classpath），所以我不明白为什么它显然不存在。我已经尝试将 xml-apis 1.4.01 显式添加到我的dependencyManagement部分（在父 pom 中，在子 pom 中有一个依赖项，并且排除了对 xml-apis 的所有其他传递依赖项）但我仍然有同样的问题，所以我开始认为我正在尝试解决错误的问题。

谁能建议出了什么问题，或者我该如何进一步调试？

您可以看到我在 Travis 上遇到的完整错误，但片段是：

mvn 依赖：树

失败模块的依赖树如下。您可以在 GitHub 上查看完整的 pom 文件（parent，child），但我不会在此处包含它们以避免超出 SO 帖子大小限制。您可以在下面看到 xml-apis 在几个地方，但 Maven 将其管理到 1.4.01。

在我的情况下，问题是通过将 xml-apis 的版本从 1.3.04 更改为 1.4.01 来解决的

看起来好像您没有xml-apis在您的子 pom.xml 中指定的依赖项。该<dependencyManagement>部分不会导致包含依赖项，它只是提供可以继承的配置。看起来您的子 pom 中的一些依赖项正在xml-apis传递，但是对于一些奇怪的 Maven 怪癖，获胜的（版本 1.4.01）在测试范围内；大概它在任何依赖项指定它的测试范围内。指定它们的 pom 中测试范围内的传递依赖项不会被测试范围内的项目依赖项引入 - 这是一个非常难以解析的句子，但是对Dependency Scope有一个很好的解释，这可能会使事情更清楚。

本质上，我正在查看的是您的依赖树，它显示了一个包含的版本xml-apis，如您的输出的编辑版本中所示：

org.xssfinder:xssfinder-test:war:1.0-SNAPSHOT
+- org.xssfinder:xssfinder-executor-java:jar:1.0-SNAPSHOT:compile
   +- org.reflections:reflections-maven:jar:0.9.8:compile
      +- org.reflections:reflections:jar:0.9.8:compile
         +- com.google.guava:guava:jar:14.0:compile
         +- javassist:javassist:jar:3.12.1.GA:compile
         \- dom4j:dom4j:jar:1.6.1:compile
            \- xml-apis:xml-apis:jar:1.4.01:test

我不完全确定为什么会通过测试范围，但我猜这就是问题所在。我建议将xml-apis依赖项显式添加到您的子 pom 中，并查看它是否会影响依赖项树 - 您试图避免将其作为传递依赖项引入，以查看是否可以解决问题。

我最终解决了这个问题，但相当不令人满意。修复是在父 pom 的 dependencyManagement 部分中将 xml-apis 标记为运行时范围。

我并不完全清楚为什么它会起作用（特别是为什么它起作用，而在编译范围内指定依赖项不起作用）。如果有人认为他们可以充分解释这一点，我想知道。

将 xml-apis 从 1.3.04 升级到 1.4.01 并且可以正常工作。
