我有一个Jenkins项目由于无法实例化我的TestNG IReporter类CustomReportListener.java（CRL）而无法运行。如果我删除对它的所有引用，该项目运行得很好，但我需要通过CRL返回结果。最后，CRL是我们作为JAR包含的一个框架的一部分，并且该测试在该JAR内部使用任何其他类看似没有问题。Maven Surefire无法在Jenkins上实例化我的IReporter类

主要错误

你能分享您的CRL的代码的问题？ – juherr

我想CRL试图使用'JFileChooser'：http://stackoverflow.com/questions/23614605/npe-in-win32shellfolder2-access-when-creating-new-jfilechooser-as-local-system-a – juherr

@juherr是的;我在开头添加了一个链接，我将其命名为缩写（CRL） –

更换行（由于失败javax.swing.filechooser.FileSystemView）

public static final String BACKUP_DIRECTORY = 
     FileSystemView.getFileSystemView().getHomeDirectory().getAbsolutePath() + "\\Selenium Results\\";

通过

public static final String BACKUP_DIRECTORY = 
     System.getProperty("user.home") + "\\Selenium Results\\";

，并预期它应该工作。

不幸的是我们不得不回滚到Jenkins的前一个工作实例等等，所以我将不得不在未来尝试这个。我会让你知道它是怎么回事。谢谢。 –

如果你的maven正在编译代码，并且.class文件存在于目标文件夹中。然后

提及Maven的扶养：

<dependency> 
<groupId>io.appium</groupId> 
<artifactId>java-client</artifactId> 
<version>2.1.0</version> 
</dependency>

并保存文件，然后重新运行，这将解决
