Copy Paste of Project results in new copied project not appearing in Working Sets

[C4J]

In previous versions of Eclipse, if you use working sets and use copy/paste to duplicate your project with a new name, then the copied project would appear in the working set called Other. Now it does not appear anywhere.

I am running Eclipse 2024-12 EE on macOS Sonoma 15.1.1

Creating a new project in the standard way does appear in the selected Working Set.

If you want to see the copy/pasted new project you have to go into the properties of an existing working set and "add" the new project to it.

Otherwise it's completely invisible.

Is this a problem in the package explorer or the project explorer? Is there a working set called other in the view? Are you showing all working set in the view?

Project explorer. I have my projects grouped into Working sets plus the default working set called Other which contains servers. I select a project, perform a copy and paste (accepting or changing the proposed new name for the copy) and is does create a copy which I can see with the operating system "finder" in the workspace directory. However the new cloned project does not appear in project explorer - I have to select the properties of a Working set and then "add" the new cloned project to the working set manually.

I have tried a fresh install of Eclipse and even imported all my projects into a clean workspace but the glitch seems to remain.

I tried debug launching my SDK development environment, changing the view to show working sets, created a project and used copy and paste to create a new one:

That works okay.

I also created a new working set and move the project to that. Then again a copy and paste and the new one shows up in Other:

Maybe something is already fixed in 4.35 development?

Or maybe my steps are different from yours?

I have done a screen recording which you can see here.

Can you drop the file directly? The drop in the markdown entry field support's *.mov and *mp4, and a bunch of other formats. I'm personally not comfortable logging into the linked site. Sorry.

I did some changes in that area with #2262 but that should only be on 4.35 afaik.

This video is perhaps more revealing as it show how duplication works differently depending on how your viewing the projects,

Thank you for sharing the video! You could test with this to see if it's fixed:

But I understand that's a fair bit of setup work just to test...

I still see the same issue. Just in case it's relevant after opening the workspace and performing a clean I get a lot of errors like this - probably to be expected ?

Thanks for the confirmation. Those errors are kind of expected when the the installation doesn't contain all the natures your projects are using so unlikely related to the problem.

I have tried this scenario and i do see the issue occur that once the project is copied in Project Explorer specifically.

• I cannot select a specific working set and paste it.
• paste at the same project level then prompted with a new name. Once the new name is given, it gets created but doesnt show up anywhere.
• I need to select that specific working set -> properties -> add -> project (test7_2 as shown in the screen shot) and click "apply and close".
  

Where as in Package Explorer, it does show up in Other Projects working set.
for reference attaching a screenshot for the same ->
