现在我正在尝试学习Jenkins的插件编程。我从Hello World教程开始，可以找到here。
java version: 1.8
maven version: 3.5.2
OS: windows 7
基本的Hello World插件适用于我，但在最后step，添加侧面板的地方，我在尝试mvn verify后总是会出现以下错误：

我检查了stackoverflow上的一些其他线程，模式找不到符号，据我所知，似乎 RunAction2 类在某种程度上缺失了。但是我从jenkins教程中知道mvn verify应该实际下载所有缺少的依赖项，所以我不知道如何解决这个问题。
我还试图将pom.xml文件中的JDK版本更改为我的实际版本，这也没有帮助。
我猜这是一个非常微不足道的错误，但作为一个血腥的初学者，我被困在这里。希望有人能指出我正确的方向。
提前致谢
答案 0 :(得分：0)
如评论中所述，这是解决方案：
您需要导入jenkins.model.RunAction2;不导入hudson.model.RunAction2;。哈德森->詹金斯
