ECF feature meta-data not being resolved properly at install time for bndtools snapshot build

[scottslewis]

I've been testing the install of ECF Remote Services feature in bnd 7.2.0 snapshots...i.e. from here:

https://bndtools.jfrog.io/bndtools/update-snapshot

These installs have been failing with the following error message:

Cannot complete the install because one or more required items could not be found.
Software being installed: Bndtools ECF Remote Services 7.2.0.202509262221-SNAPSHOT (bndtools.ecf.feature.feature.group 7.2.0.202509262221-SNAPSHOT)
Missing requirement: Bndtools ECF Remote Services 7.2.0.202509262221-SNAPSHOT (bndtools.ecf.feature.feature.group 7.2.0.202509262221-SNAPSHOT) requires 'org.eclipse.equinox.p2.iu; org.eclipse.ecf.osgi.services.feature.feature.group [2.7.100,3.0.0)' but it could not be found

This is strange, since org.eclipse.ecf.osgi.services.feature.feature.group [2.7.100,3.0.0) is available here

https://download.eclipse.org/rt/ecf/3.16.5/site.p2/3.16.5.v20250914-0333/features/ (version: 2.7.100.v20250914-0333)

as per: https://github.com/bndtools/bnd/blob/master/org.bndtools.p2/bndtools.ecf.feature.bndrun

I don't know enough about the build to say so, but it appears that perhaps the snapshot build doesn't resolve the [2.7.100,3.0.0] properly...and ignoring the qualifier.

If this turns out to be limited to the snapshot builder as opposed to the release builder then that's ok with me. Speaking of that...is there a well-known location for the latest (test) release builds?

Thanks for the report. I'll have a look.

I was not able to reproduce the error. Maybe I do something different than you or have a different environment:

• Eclipse 2025-09
• MacOS 15.6.1

Here is what I did:

• uninstalled bndtools (also made sure I have no traces of ECF)
• restarted eclipse
• installed bndtools again from https://bndtools.jfrog.io/bndtools/update-snapshot
• I checked a) bndtools and b) the ECF feature
• the I confirmed the "Trust" dialog (because not yet signed)

Result:

I try tomorrow with a fresh downloaded Eclipse 2025-09 , but at moment Eclipse download is down for me.

[scottslewis]

Hmm. Strange. I'll download a fresh version of 2025-09 tomorrow and try myself. I typically use the committer's package...same for you or something else?

Thanks for checking.

Yes, I use that too usually

[chrisrueger]

I could now reproduce the problem with a fresh Eclipse 2025-09

Cannot complete the install because one or more required items could not be found.
  Software being installed: Bndtools ECF Remote Services 7.2.0.202509290117-SNAPSHOT (bndtools.ecf.feature.feature.group 7.2.0.202509290117-SNAPSHOT)
  Missing requirement: Bndtools ECF Remote Services 7.2.0.202509290117-SNAPSHOT (bndtools.ecf.feature.feature.group 7.2.0.202509290117-SNAPSHOT) requires 'org.eclipse.equinox.p2.iu; org.eclipse.ecf.osgi.services.feature.feature.group [2.7.100,3.0.0)' but it could not be found

I suspect that somehow the ECF Update site I added in the P2 repo is not being considered.
If I add https://download.eclipse.org/rt/ecf/3.16.5/site.p2/ manually to "Eclipse Preferences / Available Software Sites" then it works

I thought that I solved this... but maybe not.

Investigating.

[scottslewis]

Thanks. If I can help, please let me know.

[chrisrueger]

@scottslewis I push PR #6842

Can you try with the pr-6842-jdk17-ubuntu-latest artifact at https://github.com/bndtools/bnd/actions/runs/18110976894

When I do that then it goes to the next page like this without error:

[scottslewis]

Good news. With this build

https://github.com/bndtools/bnd/actions/runs/18110976894/artifacts/4137162210 (java17)

And a just-downloaded and installed copy of Eclipse 2025-09 release (win64),,

I select all bndtools features

and everything works...and the install completes successfully.

So I'm closing this issue! Thanks much @chrisrueger. I'll look at pr to see what you did.

[chrisrueger]

Thanks for the feedback. I merged the PR then.
With the help of google and chatgpt I basically added the Update Site URL in two other places:

• to artifacts.xml as same as in content.xml
• to feature.xml as tag <discovery> (as described here)

Unfortunately I am not sure which of the the two made it work, but I didn't have the time at the moment for more trial and error. Maybe we find out in the future. Unfortunatelly I did not find a lot of documentation about this or very scattered throughout forums etc.

But good that it works :)
