   I'm hitting the same problem on 1.57.0 (JDT LS 1.62.0), with an existing Maven project rather than a new one. Downgrading to 1.56.0 fixes it.

   Setup: Windows, folder opened as X:\...\project, where X: is a mapped drive for \\<server>\<share>. The Maven project is in a subfolder (project\project-java\pom.xml), and there is only one pom.xml in the workspace.

   Symptoms:

   • Java Projects view: "No Java projects found in the current workspace"
   • Main class reported as "a non-project file, only syntax errors are reported"
   • Run does nothing

   Log:

   Importing Maven project(s)
   Failed to import Maven project at \\<server>\<share>\...\project\project-java\pom.xml - a project with the same name already exists (check for duplicate groupId/artifactId)
   Build projects fail: Cannot find projects from given uris. []
   

   "Java: Import Java Projects into Workspace" shows: "1 Maven project(s) could not be imported due to duplicate groupId/artifactId."

   Notes: the log shows the project under the UNC path, while VS Code uses the drive letter. Opening the folder directly through the UNC path also failed on 1.57.0, and cleaning the language server workspace did not help.
