Cannot install 3.2.2 on Eclipse 2021-06 (4.20) - missing osgi dependencies

[Vankog]

Hi,

When installing via Marketplace, I have the issue that the "osgi.bundle" dependencies cannot be resolved.

Cannot complete the install because one or more required items could not be found.
Software being installed: Enhanced Class Decompiler Jad Extension (Optional) 3.2.2 (org.sf.feeling.decompiler.jad.feature.group 3.2.2)
Missing requirement: Enhanced Class Decompiler Jad Extension 3.2.2 (org.sf.feeling.decompiler.jad 3.2.2) requires 'osgi.bundle; org.apache.commons.lang3 3.1.0' but it could not be found
Cannot satisfy dependency:
From: Enhanced Class Decompiler Jad Extension (Optional) 3.2.2 (org.sf.feeling.decompiler.jad.feature.group 3.2.2)
To: org.eclipse.equinox.p2.iu; org.sf.feeling.decompiler.jad [3.2.2,3.2.2]

Only option is apparently 3.1.1:

Am I missing something?

Thanks and best regards,
Daniel

What flavor of Eclipse do you have installed (for Java Developers, Java and Web, RCE, ..)? When I last checked them all had bundle org.apache.commons.lang3 included so there should be no problem.

Good question, I don't really know (it's a predefined bundle with some corporate-specific extensions).
Here is the info screen:

However:
Having a look over the internet seems this might be related to an unavailable Repo or at least expired certificates.
For example:
PMD had the same issue: pmd/pmd-eclipse-plugin#115

These are all available in the orbit repository, but this is very old and the certificate, with which these bundles have been signed, is expired. That's why eclipse doesn't install them automatically and claims, these bundles are not contained in any repository.

MoreUnit as well: MoreUnit/MoreUnit-Eclipse#118
There the workaround was to add
https://download.jboss.org/jbosstools/photon/stable/updates/
to the update sites.
They've added this update site as reference in the category.xml of their Update Site:
apupier/MoreUnit-Eclipse@c0be375 (mind the typo of the URL)

It seems the workaround also did the trick for ECD!!!
Maybe you are using this old "orbit" repo in transitive dependencies as well?

Similar problem here. On Eclipse 4.22.0 and attempting to install from the marketplace produces the following error:

@Sollace The ecd update site only contains the plugins in version 3.2.2. Therefore I am not surprised that Eclipse does not find the plugins of version 3.2.0 and 3.2.1. I am not sure why your Eclipse tries to download outdated plugins, may be the data it uses has not been updated?

Maybe, I don't know. The only versions I see listing for in the repo is 3.2.0. This is also the version it tries to install when using the link from the marketplace page (https://marketplace.eclipse.org/content/enhanced-class-decompiler)
