Maven依赖冲突：org.w3c.dom.ElementTraversal
我有一个Java代码库，它使用Maven进行依赖项解析和对CI运行测试。 经过最近一批开发（大到很难确定突破性变化）后，我的一些测试现在在使用带有org.w3c.dom.ElementTraversal的NoClassDefFoundError Maven运行时失败。 从我的IDE（IntelliJ IDEA）中运行时，相同的测试通过，因此可以以满足所有依赖关系的方式排列类路径。
我相信org.w3c.dom.ElementTraversal 存在于xml-apis jar 1.4.01中 （这是我依赖的 – 请参阅下面的依赖树 – 当我运行mvn dependency:build-classpath时我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中具有依赖关系，并且除了xml-apis之外的所有其他传递依赖）但我仍然有相同的问题，所以我开始认为我正在努力解决错误的问题。
任何人都可以建议什么是错的，或者我如何进一步调试？

你可以看到我在Travis上遇到的完整错误 ，但代码片段是：

mvn依赖：树
故障模块的依赖关系树如下所示。 您可以在GitHub（ 父 ， 子 ）上看到完整的pom文件，但我不会在此处包含它们以避免超出SOpost大小限制。 你可以在下面看到xml-apis在几个地方，但是Maven将它管理到1.4.01。

在我的情况下，通过将xml-apis的版本从1.3.04更改为1.4.01来解决问题
看起来您的子pom中没有指定xml-apis依赖关系。 xml-apis ，但对于一些奇怪的Maven怪癖，获胜的那个（版本1.4.01）是在测试范围内; 据推测，无论哪个依赖项指定它，它都在测试范围内。 指定它们的pom中的测试范围中的传递依赖性不会被项目在测试范围中的依赖项所引入 – 这是一个非常棘手的解析句子，但是对依赖范围的一个很好的解释可能会使事情变得更清楚。
基本上我正在看的是你的依赖树，它显示了一个包含xml-apis版本，可以在输出的这个编辑版本中看到：
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它会作为测试范围出现，但我猜这是问题所在。 我建议将xml-apis依赖项明确地添加到您的子pom中，并查看它是否影响依赖树 – 您试图避免将其作为传递依赖项拉入，以查看是否可以解决问题。
我最终解决了这个问题，但相当令人不满意。 修复是将xml-apis标记为父pom的dependencyManagement部分中的运行时作用域。
我并不完全清楚它为什么会起作用（特别是，为什么它工作，而在编译范围中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。
