Some Jira-api classes not found when upgrading Jira from 7.3 to 7.4 Edited


I wrote a small plugin with some custom fields for Jira 7.3.4.

Now we plan to upgrade to Jira 7.4, but the plugin will not start on 7.4.

I adapted the pom.xml with the new jira.version, checked the dependencies and adapted the version of all provided packages that we use (Spring, apache commons-lang, ...) to match the packages included in the new Jira. 

When starting, Jira does not load our plugin, saying:

2017-10-09 23:03:34,718 ThreadPoolAsyncTaskExecutor::Thread 1 ERROR      [] Application context refresh failed 

Caused by: class path resource [com/atlassian/jira/imports/project/customfield/ProjectImportableCustomField.class] cannot be opened because it does not exist

The ProjectImportableCustomField class is part of the jira-api 7.4.

I mentioned the following versions for the main bundles:


Do I missed something ?

Is there a new parameter that I forgot to specify ?


Thanks for your help,
