Eclipse installer hangs [message #1816668]

I try to install Eclipse 2019-09 (for Java EE) by Oomph, but it only displays the splash dialog. Nothing else ever happens. When I click on the dialog, Windows display "eclipse-inst.exe is not responding".

I all ready have Eclipse installed, but it won't starts. Just also displaying the plash screen. Nothing more ever happens. That's why I want to try installing Eclipse from the beginning. When I try start Eclipse from the Bash (GIT for Windows) Command Line it complains about:
Exception in thread "Thread-5" java.lang.NoClassDefFoundError: org/apache/xerces/parsers/DOMParser

This is the full stack trace from the command line:

org.eclipse.m2e.logback.configuration: The org.eclipse.m2e.logback.configuration bundle was activated before the state location was initialized.  Will retry after the state location is initialized.

I have also installed the newest update for Java SDK 8 (just to be sure that the Java hasn't been corrupted. I have updated JAVA_HOME and PATH.

Last week, Eclipse worked like a charm.

I use Win 10 Prof, latest Eclipse, Java JDK 8u231

The stack trace you show is the one for the IDE that won't start, not for the installer that won't start. Likely the installer (which is just an Eclipse application) won't start for much the same reason.

In this post I tried testing this particular version of Java on my local machine and that works fine:

https://www.eclipse.org/forums/index.php?t=msg&th=1101171&goto=1816636&#msg_1816636

But I got no response after that post, so I don't really know why this isn't working for someone else (or for you).

For Windows the eclipse-inst-win64.exe is like a self-extracting "zip". It will unzip to your temp folder, i,e., for me here:

C:\Users\merks\AppData\Local\Temp\eoi*.tmp

And it will use this location as the log file which will likely contain clues that will hopefully help figure out what specifically is going wrong:

C:\Users\merks\AppData\Local\Temp\eoi*.tmp\configuration\.metadata\.log

If you delete all the eoi*.tmp folders in your Temp folder and run the installer again you'll be sure you're seeing the folder for the most recent attempt to run the installer.

Thanks Ed for answering so quickly!

I did delete all C:\Users\merks\AppData\Local\Temp\eoi*.tmp and tried the installer once again.

Unfortunately, it looks like the installer hangs before it is able to write to the .log file. I can't find a eoi*.tmp\configuration\.metadata\.log file :( .

To give a lite more information, I remember that I did update a new version of IntelliJ, the week before, and it could be the new version that did something to my computer system. It looks far fetched to me, but that is one vector that has changed lately.

I have tried to update the CLASSPATH with a path to xercesImpl-2.8.0.jar that contains the xerces parser in question. To no vain. Both Eclipse and the installer fails on the same spot as earlier attempts.

When I do some Googling I find a similar stack trace here:

https://community.microfocus.com/t5/UFT-Discussions/Intellij-Idea-does-not-launch-when-upgrading-HP-UFT-from-14-1-to/td-p/1791245

I wonder if you have any strange "JAVA_*" environment variables that might lead to this behavior? Certainly if XML can't be parsed, the startup process is not likely to get very far...
