Provide "Open type" button in variables' menu

[CsCherrYY]

It would be great if we can provide this feature to help us open a type definition of a variable when debugging.

In IntelliJ, the similar feature names Jump To Type Source.

I am trying to implement this and some other commands available in Eclipse JDT Debugger. I have forked the repository. However when I try to debug the extension I always run into:

No delegateCommandHandler for vscode.java.startDebugSession

Reloading VSCode does not help as has been indicated elsewhere.

Is the correct way to develop this extension documented here.?

The strong motivation for this for me is that I can truly switch over to VS Code for Java development.

• All Instances
• All References
• Open Actual Type
• Open Declared Type

vscode-java-debug-ext addresses Open Actual Type command.

Hi Shi Chen (@CsCherrYY), 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.

Suggestion

This is an enhancement request for the VS Code Java Debugger. Currently there’s no built-in “Jump To Type Source” (like IntelliJ’s Shift + F4) in the Variables panel. As a workaround you can:

• Hover over a variable in the editor while paused—in the debug hover popup the type name is a link you can click to open its declaration.
• In the Debug Console run an expression like myVar.getClass()—the returned class link will open the source.
• Once you’re in the code, use the built-in “Go to Type Definition” command (editor.action.goToTypeDefinition) or press F12 on a type name.

If this feature would help your workflow, please 👍 the issue or add a comment to gather more community support.
