java - 执行 org.apache.maven.plugins :maven-surefire-plugin:2. 14.1:test: org/junit/runner/notification/RunListener 时缺少必需的类

Question

我有一个打包成耳朵的项目。在过去一个月左右的时间里，系统测试已被禁用。我们重新打开它们，并一直在修复失败的测试和构建脚本的问题。我一直没能破解最新的问题:

我想不通怎么找不到org/junit/runner/notification/RunListener。整个项目是使用 maven 构建的，junit 作为测试依赖项包含在内。

据我们所知，除了构建服务器外，在任何地方都可以进行完整构建。第二个有趣的点是，在构建服务器上，当不包括系统测试时，一切都构建得很好，系统测试在自己运行时也能正常工作。只有在构建包括系统测试在内的完整项目时才会出现此问题。

这是系统测试的 pom.xml 的相关部分

</plugin>

更新我想也许有一个旧版本的 junit 卡在附近可能会导致问题，所以我运行了 mvn dependency:analyze 和 mvn dependency:tree 但唯一提到的 junit 是 junit 4.10，这是合适的版本。

更新我们能够在我们的测试构建服务器上重现该问题。我之前没有提到开发人员工作站运行 Windows 8 而构建服务器是 Linux。所以这可能是 Windows 与 Linux 的问题，但我看不出是什么。

Answer 1

这个问题是两个因素的结合:

首先，存在一个传递依赖问题(即 hamcrest-core 1.1 -> jmock 1.1.0 -> JUnit 3.8.1 的问题)，其中(在 Maven 的依赖树中)较旧的 JUnit “更接近” systemTest模块(它继承了版本依赖)，JUnit 的修订版 3.8.1 没有包含 org.junit.runner.notification.RunListener。

其次，对 <version> 的解释存在混淆。由 maven 标记——有 <version>4.10</version>表示对 junit 的软要求，而不是硬要求(可能用 <version>[4.10]</version> 表示)(另见 Maven Dependency Mediation ))

后者导致 maven 接受“最接近”令人满意的 JUnit 依赖项(在本例中为 3.8)而不是预期值，从而导致错误。将 pom 更改为 [N.mm] 'hard' 语法可以解决此问题。
