Recent updates of groovy-eclipse are all failing with "Unexpected end of ZLIB input stream"

[davidmichaelkarr]

In the past few weeks, every time I've attempted to update the groovy-eclipse plugin in my 2024-03 Eclipse, it fails with this:

An error occurred while collecting items to be installed
session context was:(profile=C__Users_dk068x_eclipse_java-2024-03_eclipse, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

I just uploaded a new 4.31 (2024-03) and 4.32 (2024-06) snapshot. Can you restart eclipse and update? If it still fails, can you try the non-aggregated site link: https://groovy.jfrog.io/artifactory/plugins-snapshot-local/e4.31

I just tried again, and it failed basically with the same error, although the version numbers in the error are different:

Aren't those versions of Groovy, not the GroovyEclipse plugin?

I was able to install from the snapshot site, so it is not an issue with the files. Do you have a proxy or vpn enabled? Are you able to try the update from another network just to check?

[davidmichaelkarr]

Yes, I'm on VPN with a proxy. I tried disconnecting from VPN and disabling the proxy. That did slightly change the results, but the final result was the same. I wouldn't be at all surprised if my security-paranoid organization figured out how to block things in the Windows image we use. However, I'm not having problems with other plugins.
