The jira.home directory '……\Application Data\JIRA' is already locked.

问题：The jira.home directory 'C:\Program Files\Atlassian\Application Data\JIRA' is already locked. Please see the JIRA documentation for more information on locked jira.home directories.

解决：百度后的结果，将\Atlassian\Application Data\JIRA\.jira-home.lock文件删除重启即可

但是重启后会再次生成此文件，我直接将其删除，jira可用。

更好的解决方案：待更新……
