我正在尝试集成scribe-java并为它编写一个Jenkins插件，但似乎Jenkins不能用于Class？有谁知道这是为什么？
Jenkins插件代码：
OAuthService service =
new ServiceBuilder().provider( com.lookout.jenkins.publishoverbox.BoxApi20.class ).apiKey( clientId ).apiSecret(clientSecret ).callback(callbackUrl).grantType( OAuthConstants.AUTHORIZATION_CODE ).build();
日志：

答案 0 :(得分：0)
您在插件中需要什么，在依赖项中指定相同的内容。
原因1：
Jenkins将每个插件加载到单独的类加载器中以避免冲突。然后，插件可以像其他Jenkins内置类一样参与系统活动。他们可以参与基于XStream的持久性，他们可以提供Jelly的“视图”，他们可以提供静态资源，如图像，而且来自用户，一切都可以无缝地工作---内置的功能与插件的功能没有区别
原因2：当jenkins更改其依赖项时，您不希望更改代码。
