Could not install 2.4.0 of m2e using p2 director with eclipse 4.29

[mpet]

Hi,

We are using p2 director to distribute a set of plugins, like m2e.

We basically use the following command:

$ECLIPSE_HOME/eclipse -nosplash -application org.eclipse.equinox.p2.director -repository $iu_repository -installIU $iu_id/$iu_version" -vm $VM

For each m2e feature group we use the following info.

org.eclipse.m2e.sdk.feature.feature.group 2.4.0.20230827-1557 https://download.eclipse.org/technology/m2e/releases/2.4.0
org.eclipse.m2e.feature.feature.group 2.4.100.20230827-1557 https://download.eclipse.org/technology/m2e/releases/2.4.0
org.eclipse.m2e.pde.feature.feature.group 2.2.200.20230820-0922 https://download.eclipse.org/technology/m2e/releases/2.4.0
org.eclipse.m2e.lemminx.feature.feature.group 2.0.5.20230815-1219 https://download.eclipse.org/technology/m2e/releases/2.4.0
org.eclipse.m2e.logback.feature.feature.group 2.2.0.20230819-1220 https://download.eclipse.org/technology/m2e/releases/2.4.0

Then when we try to install the first we will have an issue ( same for the others):

Installing org.eclipse.m2e.sdk.feature.feature.group 2.4.0.20230827-1557. Installation failed. Cannot complete the install because one or more required items could not be found.

What should I do and why does it happen?

I am adding what I select in wizard:

Seems like it is not a straight forward install:

This is what I get.

I assume this is why my p2 director install does not work?

Is there a way around it?

@HannesWell do you know anything about it?

[HannesWell]

What's the base Eclipse you are trying to install into?
Maybe that's an older one or it misses some now required dependencies.
Recently we changed m2e's p2-repo to be virtually self-sontained so that you should always get all dependencies.
But this will only have an effect form the next release on.

@HannesWell and which release number are we talking about?

[HannesWell]

But this will only have an effect form the next release on.

In this statement I was referring to the upcomming m2e 2.5.0 release. You can find a snapshot here:
