i followed this guid to hide the name and email field of issue collector.
I compress the folder after my customization with this command:
jar cfM jira-issue-collector-plugin-2.0.26.jar META-INF/MANIFEST.MF jira-issue- collector-plugin-2.0.26/
When I upload the jar file via the “Manage-Add Ons” page, I get this error:
Could not install the file jira-issue-collector-plugin-2.0.26.jar. Check that the file is valid.
When I upload the original jar file, I do not get any errors.
The error is probably when recompressing the folder
Does anyone know how to do it right?
