Question

我有一个运行测试的项目。这是一个使用Selenium的maven项目。它在本地启动时运行正常，但是从Hudson平台，它会抛出NoClassDefFoundError：

SearchTest扩展了BaseSelenium。

这意味着它甚至无法在我的源文件夹中找到一个类。项目结构如下：

src/
  fr.elsevier.tests/
    disponibilite/
      SearchTest.java
    BaseSelenium.java
pom.xml

为什么构建会生成这些NoClassDefFoundErrors以及如何修复它？

Answer 1

尝试在local和hudson构建中使用-e或-X命令行参数。然后尝试比较启动的java进程的类路径。

然后，您可以实际找出maven生命周期的哪个部分通过更好的堆栈跟踪抛出异常。

当hudson运行maven项目时，NoClassDefFoundError
