Running Eclipse Marketplace leads to error message [message #1829960]

I'm running Eclipse 0620-03 under Linux Mint 19 on a Dell Lattitude E6420.

It doesn't have WindowBuilder installed.

I google searched "WindowBuilder" and started to follow the directions. That is to say, I clicked on "Help --> Eclipse Marketplace."

When I did, I got the following error message:

MarketplaceDiscoveryStrategy failed with an error
Cannot complete request to https://marketplace.eclipse.org/api/p?client=org.eclipse.epp.mpc.core&client.version=1.8.2.v20200210-1402&os=linux&ws=gtk&nl=en_US&java.version=11.0.4&product=org.eclipse.epp.package.java.product&product.version=4.15.0.I20200305-0155&runtime.version=3.17.100.v20200203-0917&platform.version=4.15.0.v20200305-0155: Unable to read repository at https://marketplace.eclipse.org/api/p?client=org.eclipse.epp.mpc.core&client.version=1.8.2.v20200210-1402&os=linux&ws=gtk&nl=en_US&java.version=11.0.4&product=org.eclipse.epp.package.java.product&product.version=4.15.0.I20200305-0155&runtime.version=3.17.100.v20200203-0917&platform.version=4.15.0.v20200305-0155.

Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

I recently posted another problem that I have that involves WindowBuilder, this one with Eclipse 2020-06, so I don't want to upgrade until this other issue is resolved. (Then again, for all I know, 2020-06 may have this issue too, but I'd prefer to remain safe.)

One of the problems here is that this involves Eclipse's internal tables, which are VERY poorly documented. And YES I WILL WRITE THE STUFF IF YOU DEEM IT NECESSARY.

Is it worth it to install WindowBuilder or has the latest version of Eclipse deprecated it? What tools are currently used to edit a GUI? Regardless of these issues, what is causing the error that I'm getting?

Thank you for your time; I look forward to your response(s).

Since I was able to resolve the problem with WindowBuilder on Windows 10, I decided to upgrade the Eclipse I have running under Linux Mint to 2020-06.
I downloaded the file, extracted it to a separate directory and doubleclicked on the installation program's icon.

I got (and keep getting) the following error message:

The catalog could not be loaded. Please ensure that you have network access and, if needed, have configured your network proxy.

I then brought up firefox and used it to surf this website. The network connection is fine.

Maybe this has something to do with Eclipse's inability to get the WindowBuilder plugin on that machine.

What am I doing wrong?

Both problems suggest that your Windows 10 machine might be blocking the eclipse/installer applications from properly accessing files from the internet. Alternatively, perhaps you're running with an old JRE/JDK that does not have the latest root certificates in its certificate store.

But you say this second problem happens only on Linux? There firewalls should not be an issue. The installer is specifically trying to download this file via this URI:

https://www.eclipse.org/setups/setups.zip

I assume that a browser is able to access that URI on that system?

Running like this on the command line would provide some clues:

./eclipse-inst.exe -vmargs -Doomph.setup.ecf.trace=true 2>&1 | tee log

Sorry, this is for Windows running in a Git bash shell and the tee is because the executable is not properly hooked to print to the console. For Linux it would just be

eclipse-inst -vmargs -Doomph.setup.ecf.trace=true 2>&1 | tee log

Though here it would print trace information to the console without the tee.

With respect, I don't see how the Windows 10 machine has anything to do with this. The two machines are on separate wires from a 4-station router. They operate independently.

I tried going into the directory that the installer tar.gz file extracted to, found eclipse-inst, ran it as per the above instructions and got the same message about being unable to load the catalog.
I also tried cat-ing the log file when the whole thing was does and it is empty.
I have no clue as to why this thing does not want to work.

I did ask because there are multiple problems in your thread and multiple threads with network-related problems.

I suggested running "eclipse-inst -vmargs -Doomph.setup.ecf.trace=true" on Linux, not to fix the problem, but to collect trace details that might help understand why it's failing to load the catalog, i.e., to gather a trace like the one I've attached.

There's also a log in configuration/*.log, but I doubt that will be as helpful in terms of this particular failure. Trace/log details might help to understand why it fails for you but 30,000 other people used the most recent installer version successfully on Linux.

Without some clues, all I can suggest is that you download a package directly:

https://www.eclipse.org/downloads/packages/

Thank you for the clarification; however, I could not get different results from reloading and reextracting the tar.gz file.
This was actually the way that I had attempted to install eclipse previously. Mind you, I am not complaining. I am glad for the attempt to help.
Nonetheless, I have three tar.gz files now that extract nicely into an install directory and then tell me that they can't download the catalog
when I try to run the installer. This seems like a network configuration problem to me, but I don't know how the network connections
are set up on eclipse.org's download pages.

If it helps, I'm not a complete newbie. I'm 56 years old and have a bachelor's degree in comp sci from RIT, and have been using Linux for quite a while.
You need not hold back.

If you've downloaded the installer and it runs sufficiently so to bring up the UI and complain that it can't load the catalog, then there is nothing wrong with what you've downloaded, i.e., it's not corrupted, so redownloading that is highly unlikely to produce different behavior. The application is trying to download https://www.eclipse.org/setups/setups.zip and that's failing. Cached versions of what the installer downloads are stored in ~/.eclipse/org.eclipse.oomph.setup/cache and it it were successful, the files https___www.eclipse.org_setups_setups.zip and https___www.eclipse.org_setups_setups.zip.etag would exist in that folder.

I suggested running with "eclipse-inst -vmargs -Doomph.setup.ecf.trace=true" on the command line because this produces a detailed trace of the part of the framework that is downloading the catalog (setups.zip). With that information I would likely better understand what is going wrong. The installer also uses the configuration folder as the "workspace", so if some problem is logged, there will be a log file in <installer-folder>/configuration/.metadata/.log. There might be clues here has well.

Without some clues, I don't know what could be wrong in your particular case.
