When creating a new, empty project, project wizard complains of location overlap

When creating a new, empty project, project wizard complains of location overlap (see attached screen clip)

I selected the project type as "Empty or existing CMake Project" whose description suggests I should be able to create the project on top of the existing source tree (see other attached screen clip)

What am I doing wrong?

Is it possible that you had a previous project in this workspace with the same folder name that was deleted at filesystem level rather than from within the Eclipse workbench? Try moving the new project folder to somewhere outside the workspace root and add it again.

Eclipse is newly installed. I started this job last week and was using Gnome Text Editor while waiting for IT to install Eclipse.

Knowing I was going to be using Eclipse, I created a folder for the work space then a folder for the project and cloned from git into that folder.

So, there was no project, simply a source tree.

This is under Ubuntu 24.04 LTS

You get that error when a folder you're trying to create a project in already contains an Eclipse project descriptor that can come from your git repo. See if the mono directory in home has a .project file following git clone. If so use "import existing projects into workspace" instead.

[ronww]

There is no .project file in git, so "git clone" could not have created one.

I tested in a new folder and Gnome Text Editor also did not create a .project file.

That message should only happen under two cases:

1. You already have a project in your workspace called "mono" (seems unlikely based on your comments so far)
2. You have overlap of workspace and folder.

What workspace are you using? If it is /home/XXXXX/mono that would be the problem. The workspace and the the project directory should be different. e.g. use /home/XXXX/workspace as your workspace and /home/XXXX/mono as your project.

You can have workspace of /home/XXXX/workspace and project as /home/XXXX/workspace/mono.

HTH

/home/xxxx/mono already existed before Eclipse was installed.

When first launching Eclipse, I chose /home/xxxx as the workspace then tried creating an Eclipse project on top of /home/xxxx/mono

The description of "Empty or Existing Cmake Project" implies that is possible

[gvl2023]

If the project directory is inside the Eclipse workspace the project name must be the same as the project directory name. Call the project mono and leave "use default location" checked, it should work. If the project directory is outside the workspace then there isn't such a restriction.

[ronww]

Thanks.

Unfortunate that the dialog panel does not state that

[gvl2023]

Agreed this is not the most useful error message in the world, but folders inside the workspace are reserved for projects with corresponding names by definition, so technically it is correct.
