Jenkins从2.319升级到2.346后，Jenkins启动失败，报错:

之前的升级没有任何问题。我没有在发布说明中找到关于这些变量的任何参考。同样，在升级指南中，没有找到与这些变量相关的更改的参考。
经过调查和检查Jenkins代码，我找到了原因。
在config.xml文件中，我必须改变2个标签的值:
<workspaceDir>D:JenkinsDataWorkspaces${ITEM_FULLNAME}</workspaceDir>
<buildsDir>D:JenkinsDatajobs${ITEM_FULLNAME}builds</buildsDir>
<workspaceDir>D:JenkinsDataWorkspaces${ITEM_FULL_NAME}</workspaceDir>
<buildsDir>D:JenkinsDatajobs${ITEM_FULL_NAME}builds</buildsDir>
修改后，Jenkins可以正常运行。
