您从哪里获得有关API的信息? Atlassian上的文档已过时.

Where did you get the info about the API? The docs on atlassian are outdated.

首先，您的pom.xml应该如下所示:

First of all your pom.xml should look like this:

尝试先更改pom，看看是否可以解决.您可以在此处看到完整的示例: https://github.com/somaiah/jrjc

Try changing your pom first to see if this fixes it. You can see a fully working sample here: https://github.com/somaiah/jrjc
