当我尝试在 Jenkins 中创建一个“新项目”时，我只能选择创建一个自由式项目，而没有其他选项

Question

我有兴趣在 Jenkins 中为我的 EKS 集群创建一个多分支项目。 出于某种原因，当我单击“新项目”时，我只能选择创建一个自由式项目，并且我无法选择多分支或任何其他选项，它们甚至不存在于该页面上出于某种原因。

这是用于我的 EKS 集群的 jenkins.yaml 文件，以防万一它导致问题

如果你有一个基本的 Jenkins 安装（即：只是战争），那么你只会看到默认的“自由式作业”选项。 为了拥有其他项目类型的选项，您必须安装适当的插件。 例如，如果你想用文件夹来组织你的工作，那么你必须安装文件夹插件。 您可能遇到的插件提供的所有附加功能也是如此。

初次启动时，您会看到安装推荐插件的选项。 如果你跳过它，你也可以在之后这样做。

就您而言，我相信您需要安装Branch API plugin 。 这还将安装所有必需的依赖项，包括核心 Pipeline (Workflow Aggregator) 插件、 Pipeline: Multibranch插件和Pipeline: Job 插件。 根据您的需要（即：步骤），您可能仍需要其他插件。

然后，您可以选择创建其他作业类型：管道、多分支管道和组织文件夹。
