我设置了 Bitbucket 团队项目来扫描组织文件夹并创建管道，但在没有 Jenkinsfile 的情况下作业失败

预期结果：应该忽略没有 Jenkinsfile 的存储库实际输出：上面提到的失败错误

Jenkins 版本：2.1.83 Bitbucket 分支源码插件版本：2.4.5

【解决方案1】：

如果有另一个文件用于标记存储库对构建有效，您可以使用远程文件插件。

在这个插件中有一个名为Local File 的字段。如果您在此处定义文件名，例如pom.xml，则只会创建包含该文件的存储库和分支。

这是来自插件的文档。

When using Remote File Plugin, you might want to build only repositories and branches which contain a certain file. In this case, you may specify a Local File in the Plugin SCM Definition. This way, Jenkins will create projects only for repositories and branches containing the file you specified.

【解决方案2】：

默认情况下，插件会尝试读取所有没有 JenkinsFile 构建的分支。为了克服它，对于所有测试分支（您不想构建作业），您必须维护与实际分支（您想要构建的分支）不相似的不同分支名称。

并且在 Job 配置中，你可以让正则表达式匹配你的实际分支，这样 Jenkins 就会忽略剩余的分支。
