"Invalid project description"

[jukzi]

After updating my platform workspace i found the following exception in my log:

org.eclipse.oomph.resources.backend.BackendException: org.eclipse.core.internal.resources.ResourceException: Invalid project description.
	at org.eclipse.oomph.resources.backend.BackendContainer.importIntoWorkspace(BackendContainer.java:158)

At least i would like to know which project the exception is complaining about in the exception message.

@merks Ed can you take a look please? The enhanced error message now blame some oomph related things:

Is there something off about the about the content of this file, i.e., the .project file located at file:/C:/Users/jkubitz/platform-2024-09-23/git/eclipse.platform.ui/releng/org.eclipse.ui.releng:

This works fine for me and as you can see in the first picture, the project is imported into the workspace so the description file must be fine.

[jukzi]

i can't see the project in my package explorer even though git "import project" says it is already imported

[jukzi]

i found it in package explorer - with a wrong name?

it was recently renamed 2a523839813b20be41480d42e43e4ba42bd87bae

[merks]

That leaves the workspace in kind of an inconsistent state. I suppose if you delete the project (without deleting it on disk), it will be imported with the correct name and the problem will go away...

[jukzi]

ok, thanks that helped fixing it. Maybe one should move the project path to stick with the pattern, that name and path are the same @HannesWell

[merks]

Yes, it's kind of confusing when the folder and IProject names are different...

[HannesWell]

Maybe one should move the project path to stick with the pattern, that name and path are the same @HannesWell

This was done in an attempt to have a similar naming pattern for all projects containing setups without changing the paths of the setups. Because the latter is much more work, because it requires adjustments of the Oomph index. Not impossible, but more work.

[merks]

Yes, this is referenced via absolute URI from another setup, i.e., this one. So if the path were to be changed, the URI would need to be changed here:
