Cannot create an MVS subproject

An attempt to create an MVS™ subproject fails with a duplicate name message.

Symptom

When you attempt to create an MVS subproject, you receive the following message: A subproject with the same name already exists in the project.

Diagnosing the problem

This message can be displayed when a previous attempt to create an MVS subproject with the same name ended incompletely. This situation can occur when, for example, you chose this same MVS subproject name but ended the subproject creation operation partway through the definition.

Resolving the problem

  1. Click Window (on Windows) or IBM® Developer for z/OS® (on macOS) > Show View > Other > General > Navigator.
  2. From the Navigator view menu, select Filters.
  3. Clear the wdz_proj_* checkbox.
  4. Look for a subproject named wdz_proj_duplicate_name, in which duplicate_name is the subproject name that generated the error.
  5. Delete this subproject.
  6. From the Navigator view menu, select Filters.
  7. Select the wdz_proj_* checkbox. You can now create the subproject with the duplicate name.
