Eclipse Mylyn JIRA integration keeps failing with constant errors

I recently got the newest version of Eclipse and I’m trying to set up JIRA integration through Mylyn but I keep running into problems. Every time I try to connect or configure it, some kind of error pops up. I even tried installing the Tasktop connector thinking that might fix things, but it’s still not working properly. The errors happen consistently and I can’t seem to get past them no matter what I try. Has anyone else dealt with this issue before? I’m not sure what step I’m missing or if there’s a specific configuration that needs to be done. Any help would be really appreciated, thanks!

same headaches here last month. clear your eclipse workspace metadata first - old mylyn configs screw things up. also check if your jira permissions allow api access. most admins disable it by default. what error messages are you getting?

Had the same headache 6 months ago. Turns out it’s usually a version mismatch between Eclipse and the Mylyn JIRA connector. Newer Eclipse versions hate older connectors and vice versa. I fixed it by downgrading to Eclipse 2022-12 and grabbing the Atlassian connector from Eclipse Marketplace instead of Tasktop. Try this first though - create a fresh workspace and install just the JIRA connector, no other Mylyn stuff. Plugin conflicts cause weird errors like this all the time. Also check if your JIRA has custom auth like SAML or OAuth - that’ll mess with Mylyn’s basic auth.

JIRA-Mylyn integration is super finicky, especially with newer Eclipse versions. I’ve hit the same issues - it’s usually authentication problems. First, check your JIRA server URL format. For JIRA Cloud, it needs to end with /rest/api/2. For server instances, use your specific REST endpoint. Test your credentials directly in JIRA’s web interface before trying Eclipse. If you’re using HTTPS, certificate issues are common. Try disabling SSL verification in Eclipse’s network settings temporarily to see if that fixes it. Still having problems? Check Eclipse’s error log view - it’ll show more detailed error messages that point to what’s actually failing.
