I tried to using tycho to package eclipse product archive for my eclipse application.
The tycho throws the following errors:

[ERROR] Cannot resolve project dependencies:
[ERROR] Software being installed: EtaCATStudio 0.1.0
[ERROR] Missing requirement: EtaCATStudio 0.1.0 requires 'org.eclipse.equinox.p2.iu; com.mackerelpike.plc.ide.feature.feature.group 0.0.0' but it could not be found

--------------------------------------------------
I googled org.eclipse.equinox.p2.iu, But nothing found!
Can anyone tell me How to solve this problem?
Thanks!

I answered this on the JDT forum. Note that "org.eclipse.equinox.p2.iu" in this context is a namespace. The thing after the namespace is the name. So it's the iu (installable unit) for the name com.mackerelpike.plc.ide.feature.feature.group that cannot be resolved. It is a feature and you must specify the p2 repository where it is located.

can you show me url on the JDT forum or some snippets.
I had a similar problem.

The tips as follows:
Cannot complete the install because one or more required items could not be found.
Software being installed: RCP Product 1.0.0.202311080340 (wellcontrol 1.0.0.202311080340)
Missing requirement: RCP Product 1.0.0.202311080340 (wellcontrol 1.0.0.202311080340) requires 'org.eclipse.equinox.p2.iu; org.antlr.runtime [4.7.2.v20221112-0806,4.7.2.v20221112-0806]' but it could not be found

But I don't know where "4.7.2.v20221112-0806" came from

my tycho's version is <tycho.version>4.0.3</tycho.version>

Thank you

I can see the version in https://download.eclipse.org/acceleo/updates/milestones/3.7
as in the attachments

How can I use it? add in the pom.xml?

	
<repository>
	<id>antlr</id>
	<layout>p2</layout>
	<url>https://download.eclipse.org/accceleo/updates/milestones/3.7</url>
</repository>

But the error has not been changed.

Where is the iu should be installed?
How can I check the iu has been installed?

I don't know how you are setting up your target platform used in the build. You'd typically add it to your *.target file. Maybe this helps:
