I've been trying to install WTP in Eclipse 2023-09, running on Ubuntu 22.04, and keep running into this error:

Cannot complete the install because one or more required items could not be found.
  Software currently installed: JustJ Adoptium OpenJDK Hotspot JRE Complete 17.0.9.v20231028-0858 (org.eclipse.justj.openjdk.hotspot.jre.full.feature.group 17.0.9.v20231028-0858)
  Missing requirement: JustJ Adoptium OpenJDK Hotspot JRE Complete 17.0.9.v20231028-0858 (org.eclipse.justj.openjdk.hotspot.jre.full.feature.group 17.0.9.v20231028-0858) requires 'org.eclipse.equinox.p2.iu; org.eclipse.justj.openjdk.hotspot.jre.full [17.0.9.v20231028-0858,17.0.9.v20231028-0858]' but it could not be found

I do have this JRE install but it doesn't make much difference

~/.p2/pool/plugins/org.eclipse.justj.openjdk.hotspot.jre.full.linux.x86_64_17.0.9.v20231028-0858/jre

I've also tried installing a number of other JDKs (11, 17, 21) but nothing seems to make a difference. What is it looking for and how can I fix this?

All the packages come with JustJ installed. You can find all the parts needed in this update site:

https://download.eclipse.org/justj/jres/17/updates/release/latest

Is this site not listed in Window -> Preferences -> Install/Update Available sites?

https://download.eclipse.org/justj/epp/release/latest

Given the 2023-12 release is out, might you be better off installing that?
