Question

我有一个打包成耳朵的项目。过去一个月左右，系统测试已被禁用。我们重新打开它们并修复了测试失败和构建脚本的问题。我无法解决最新的问题：

我无法弄清楚无法找到org / junit / runner / notification / RunListener。整个项目使用maven构建，junit作为测试依赖项包含在内。

据我们所知，除了构建服务器之外，完整构建可以在任何地方工作。第二个有趣的一点，在构建服务器上，当系统测试不包括在内并且系统测试在自己运行时工作正常时，一切都很好。只有在构建完整项目（包括系统测试）时才会出现此问题。

这是系统测试pom.xml的相关部分

    </configuration>
</plugin>

更新我想也许有junit的旧版本可能会导致问题，所以我运行了mvn dependency:analyze和mvn dependency:tree，但唯一提到junit的是{{1} }，这是合适的版本。

更新我们能够在测试构建服务器上复制问题。之前我没有提到开发人员工作站运行Windows 8而构建服务器是linux。所以它可能是一个Windows vs linux问题，但我看不到。

Answer 1

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 - ＆gt; jmock 1.1.0 - ＆gt; JUnit 3.8.1），其中（在Maven的依赖树中）较旧的JUnit“更接近” systemTest模块（继承了版本依赖关系），JUnit的修订版3.8.1没有包含org.junit.runner.notification.RunListener。

其次，maven对<version>标签的解释存在混淆 - <version>4.10</version>表示对junit的 soft 要求，而不是硬性要求（可能会显示为<version>[4.10]</version> （另见Maven Dependency Mediation））

后者导致maven接受'最接近'令人满意的JUnit依赖（在本例中为3.8）而不是预期值，从而引起错误。将pom改为[N.mm]'hard'语法可以解决这个问题。

Answer 2

我在重建开发环境时遇到了类似的问题。少数罐子下载不正确。我能够继续从我的maven存储库中删除问题文件夹。这迫使maven再次下载它们，然后它们没有问题地工作。

在这种情况下，我删除了：

{local_repo} \组织\阿帕奇\行家\插件\行家-万无一失-插件

执行org.apache.maven.plugins时缺少必需的类：maven-surefire-plugin：2.14.1：test：org / junit / runner / notification / RunListener
