The problem is that https://marketplace.eclipse.org/ is currently not reachable. There seems to be a general problem with this server since this has happened various times in the last week. Denis, could you have a look at this?

Despite from the server problems, it would of course make sense that the marketplace client provides a better error message in those cases. We will have a look at that.

By Vicky Ronnen

The problem is caused by not correctly handling http: to https: switch.
The solution:

Stop eclipse

Edit file ~/eclipse/jee-2020-03/eclipse/configuration/org.eclipse.epp.mpc.ui/MarketplaceInfo.xml
and replace ALL http: to https:
Restart eclipse
And now the marketplace client works without any problem.

this?

I've been chasing this for years. There is a request, or series of requests, or something... something that causes the MP servers to peak their load average for several minutes. This has been happening sporadically for years, and I've never been able to pinpoint it.

Thanks for noticing it.
@Denis @Leif: this file is on server side, isn't it? Is there an open repository we can author a patch to fix this, or does it have to be done by webmasters?

By Vicky Ronnen

File is on the developers pc after installation of eclipse in the mentioned directory. Comes with the distribution I presume,
Having everything https makes things easier.
Somehow the switch from http to https not handled correctly.
That's the real cause. My fix is a usable workaround.

Keep in mind first impression of using an ide is decisive.
If it doesn't work out of the box you will lose a user.
So install on a clean pc windows/linux/ios and verify basic functionality is working out of the box.

It made me switch to intellij...

No, this is a purely client-side cache file. We'll need check the http-to-https migration path in MPC.
