我在JIRA 7上使用了JIRA Mercurial插件（https://bitbucket.org/servicerocket-labs/jira-mercurial-plugin/overview） . 它在JIRA 6.4.7上工作正常（通过atlas-run-standalone --product JIRA --version 6.4.7） . 长话短说 - 我've only just upgraded my private JIRA server to JIRA 7, and this is the only thing that doesn'工作......
在JIRA 7.1.9上，Mercurial Repositories配置页面抛出404错误，我在catalina.out中获得了大量的回溯（复制如下） .
我无法让它在atlas-debug或atlas-run中运行 . 我能够让插件运行的唯一方法是运行JIRA独立运行 .
我从atlas-debug和atlas-run得到的错误是：
[ERROR] Failed to execute goal com.atlassian.maven.plugins:maven-amps-dispatcher-plugin:6.2.4:debug (default-cli) on project mercurial-jira-plugin-project: Couldn't detect an AMPS product to dispatch to > [Help 1]
任何人都能为我提供一些帮助吗？
我怀疑这是一个依赖问题 - servlet API升级似乎是一个可能的候选人（https://developer.atlassian.com/jiradev/latest-updates/preparing-for-jira-7-0/jira-7-0-platform-changes#JIRA7.0-Platformchanges-servletapi） . 不幸的是，我的Java知识可以追溯到大约十年，而Atlassian文档中的有限文档（"just add a dependency in the project pom file"）正在我脑海中浮现......
谢谢 .
Backtrace如下：
