Spring Tools Suite 4 download fails with Eclipse Photon

Question

I'm using Eclipse Photon and Windows 10 and trying to download the STS version 4 from the marketplace (or by drag and drop) the installation constantly stalls at 49 percent and I get this error:

Any tips or help appreciated!

Answer 1

This looks like a typical network or repository caching issue. I would recommend to go to the Preferences -> Install/Update -> Available Updtae Sites , select the one that is used and press reload . That refreshes the internal repository caches. Then try again the install. You could also delete all those STS-related update sites from that preference and try again the marketplace entry. That should solve the issue.
