我有一个 SWT 应用程序（不是基于 Eclipse RCP），我目前使用 SWTBot 对其进行测试。这在从 Eclipse 运行测试时工作正常。我正在使用 ant 作为构建系统。

在 Jenkins 上，测试失败 - 抛出异常

搜索这个特定问题并没有找到任何有用的解决方案。

编辑：

添加 jvm args 来设置美国英语修复了这个问题并使一些测试运行；所有其他带来以下堆栈跟踪：

关于java.lang.ExceptionInInitializerError

我注意到有/已经存在与 DE_DE 语言环境缺少键盘布局有关的 Eclipse 错误。我能否建议您检查运行 junit 测试的进程的语言环境设置。如果您将语言环境设置为 en_US，是否还会出现问题？

Apart from setting the locale for the server process (e.g. LC_ALL environment variable?), perhaps you could use explicit locale in your junit task, e.g.

<junit fork="yes">
  <jvmarg value="-Duser.language=en"/>
  <jvmarg value="-Duser.region=US"/>

Regarding org.eclipse.swt.SWTException: Widget is disposed

Maybe this is exposing a real bug in your UI code, but I suspect you need to look at your unit tests. Are they stateless, or do they depend on a certain execution order to work reliably? Perhaps this error can arise if the tests are executed in a different order than you expect.
