Eclipse 2022-06 (4.24.0) can't connect to update server [message #1853757]

I installed Eclipse 2022-06 (4.24.0) to a new machine using the Eclipse IDE for Java Developers option. Now it's looking like I'm going to need Java EE. So I went into Help/Install New Software and selected the required items. But when it tries to actually download them, it can't reach the required server(s). In fact, it fails to check for updates with a similar error. I see nothing in the firewall records for Windows Defender. The exception when it tries to update is below.

Does anyone know what's going on?

An error occurred while collecting items to be installed

I had similar problems today. Try Window -> Preferences -> Oomph -> Bundle Pools -> Clear Cache... to throw away (delete) all local cached update site information and load them from the internet freshly.

These are all present in this repository (as you can see using the Repository Explorer view):

https://download.eclipse.org/oomph/updates/milestone/latest

Generally this type of problem happens when the loaded content metadata and artifact metadata are not in sync. Flushing the caches often helps. But even then, p2 keeps soft references to already-loaded repositories and the only way to force flush those is to restart.

I've restarted both Eclipse and Windows. It still doesn't connect. So what do I need to restart?

Did you tell it to contact all available update sites? In Windows -> Preferences -> Install/Update -> Available Software Sites all the check-marked update sites will be used. You can disable ones for which/where you don't want to look for updates while installing. Or add https://download.eclipse.org/oomph/updates/milestone/latest if that's missing.

Or create a new JEE installation instead of updating what you have...

Yes.

I reinstalled Eclipse specifying EE shortly after I started this thread.
