This is a preview of incoming 2.0 stable release (not scheduled yet). The code is quite stable and we're missing only few issues before releasing 2.0.
The documentation is for now outdated - it will be updated while releasing stable version.
For the sample usage please refer to source code: https://bitbucket.org/atlassian/jira-rest-java-client/src/75a64c9d81aad7d8bd9beb11e098148407b13cae/test/src/test/java/samples/ExampleCreateIssuesAsynchronous.java?at=master
Important notes:
- The new version is asynchronous, so you can run many requests in the same time!
- Support for Jira < 5.0 was dropped to increase development speed.
- Code was split into few modules, so if you use maven please update your dependencies to com.atlassian.jira:jira-rest-java-client-core:2.0.0-m19.
