Create Java Project wizard doesn’t show template list offline (since v0.26.3)

[zylex7]

Since updating Project Manager for Java to version 0.26.3, the "Create Java Project" wizard no longer works offline.

When I open VS Code and run the command Java: Create Java Project, the list of templates ("No build tools", "Maven", "Gradle") does not appear. The extension just loads indefinitely at the bottom (shows "Java extensions are loading") and nothing happens.

When I turn on my internet connection, the template list appears immediately and everything works again.

This issue did not happen in version 0.26.2 and earlier — I was able to create Java projects completely offline before the update.

Notes

• Rolling back to version 0.26.2 immediately restores offline functionality.
• The problem clearly began with 0.26.3.
• Appears to be a regression where template metadata is now fetched from an online source.

Hi @zylex7, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Suggestions

• Workaround: downgrade to v0.26.2
  Roll back the extension to 0.26.2 until a fix is released:

  code --install-extension vscjava.vscode-java-project-manager@0.26.2

• Cache templates online once
  Connect to the internet, run Java: Create Java Project so the template metadata downloads. After that you may be able to work offline until you reload VS Code.

• Report the regression
  File a detailed issue (including your OS, VS Code version and logs) at the Project Manager for Java repo:

@zylex7 This is indeed an interesting finding. I’d like to confirm that your vs code has the Copilot Chat extension installed, correct?
