Modified Bundled Plugin won´t load

[P1ll3]

Hello,

we modified the jira-user-profile-plugin-4.0.3. We use JIRA Server 8.6.1.

Compilation and packaging from source was successful. We exchanged the jar in the corresponding WEB-INF directory. We deleted the plugin cache as well.

The Plugin won´t load and we see a message in the logs like:

'com.atlassian.jira.jira-user-profile-plugin' - 'Atlassian Jira - Plugins - User Profile Plugin' is unaccounted for.

Why is the plugin not getting loaded/started?

It is even not getting loaded when we just replace the class and vm files in the original jar file (and again deleted the plugin cache).

One of the admins accidentally tried to install the plugin manually through the administrative page when jira was running. Could this be the cause for this error message? How can we clean this up?

The plugin is not disabled (even not listed there) in the table pluginstate.

We tried several approaches but we cannot get the problem solved.

Thanks and best regards.

The problem was a missing annotation @ComponentImport at for a new parameter GroupManager in the constructor.
We saw following exceptions in the log:

java.lang.RuntimeException: Unable to enable web fragment

The Plugin is compiled with a newer version of JDK than the JIRA runs on but both are of version 1.8.

OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.202-b08, mixed mode)

Plugin was built with
