在Jenkins上运行Maven Web驱动测试，无法识别的错误

Question

在使用EclipseIDE用Java编写了一些测试之后，我们想让它们在部署后自动运行。我已经将Maven配置为几乎与Jenkins一起工作，但还有一些问题。以下是其中之一：我试图运行一个无头文本（xvfb，firefox）ion jenkins，但输出如下：（我甚至无法确定问题出在哪里）

<===[JENKINS REMOTING CAPACITY]===>channel started

log4j:WARN No appenders could be found for logger (org.apache.commons.beanutils.converters.BooleanConverter).
log4j:WARN Please initialize the log4j system properly.

Answer 1

看起来这个错误被JENKINS-15935这个bug覆盖了。它在Jenkins版本1.526中进行了更正，根据变更日志，修复似乎还没有进入LTS版本（截至版本1.509.3）。

当我遇到这个错误时，我只是切换回Maven 3.0.5，它为我纠正了这个问题。一旦我有时间更新我们的詹金斯安装，我会再给Maven 3.1一次机会。

Answer 2

查看异常跟踪，您在获得ClassNotFoundException时缺少了一些类，因此InvocationTargetException。如果你还没有尝试过的话，你可以尝试几件事。

1. 升级你的maven

你可能可以在这里找到答案。希望有帮助
