Jenkins与GitHub和Ionic项目的集成问题

我正在尝试将ionic应用程序与Jenkins集成，并将GitHub用作存储库。当我手动运行多分支管道作业时，Jenkin显示以下错误

有人知道可能出现什么问题吗？我试图学习CI/CD如何与这个演示实验一起工作

我指的是Youtube视频：

詹金斯作业配置：

经过几天的分析，我终于找到了解决办法。我犯了一个非常基本的错误，没有阅读运行Jenkins的版本要求

正如上面URL中提到的，在“运行Jenkins”一节中，他们清楚地提到了运行Jenkins作业的java支持版本。所以我检查了java版本，它是在Java13-a上运行的，是的，这很愚蠢，因为Jenkins作业只能在java版本8和11上运行

因此，将您的java版本降级为8或11，它将顺利工作

证明

我本想删除我愚蠢的问题，但后来我想保留它，如果它能帮助别人的话。请不要给这篇文章任何类型的（+ve或-vew）分，因为它没有任何意义
