Spring Tool Suite (STS) 3.7.3 RELEASE Updating Software

Question

When I am doing Help --> Check for Updates ... I am getting an error below. Tried clearing p2 cache directory and restarting IDE many times but it did not help. Tried disabling the SpringSource update site as well but it did not help either. I am also attaching the snapshot of the update sites below. Please help!

Answer 1

The issue mostly has to do with stale cached data (I experienced the same). The following should solve your problem.

1. Go to: 'Preferences > Available Software Sites'
2. Mark all, and 'Export' to file.
3. Delete everything (all the links)
4. Close and Start STS
5. Go to: 'Preferences > Available Software Sites'
6. 'Import' from the previously saved file.
7. Go to, 'Help > Check for updates'
8. Update

Basically this procedure clears up all the stale data.
