How to develop this extension. Get "No delegateCommandHandler for vscode.java.startDebugSession" while debugging the extension

[sandipchitale]

I am trying to implement 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.

BTW I also tried to build vsix package and install it. That runs into same issue.

Will restarting JLS help? Or may be disable enable extentions?

I think this has something to do with the order of activation of extensions. Is there a way to control the order of activation of extension?

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.

Expected Result

I should be able to debug the extension.

In addition, I am trying to also implement Groovy support so that I can debug gradle build scripts. I am familiar with JDWP (JDI) and I know that JDI does support higher level JVM languages like Groovy, JSP.

I think this has something to do with the order of activation of extensions.

I see this in JLS.log:

Contains: Cannot extract bundle symbolicName or version c:\professional\vscode\extensions\vscode-java-debug\server\com.microsoft.java.debug.plugin-0.34.0.jar
java.nio.file.NoSuchFileException: c:\professional\vscode\extensions\vscode-java-debug\server\com.microsoft.java.debug.plugin-0.34.0.jar
at java.base/sun.nio.fs.WindowsException.translateToIOException(Unknown Source)
at java.base/sun.nio.fs.WindowsException.rethrowAsIOException(Unknown Source)

And I do not see the server folder in my project. Maybe that is the issue.

Ah... CONTRIBUTING.md may have what I need. Will give that a try.

I think following CONTRIBUTING.md helped. You can close the issue.

I suggest that add an explicit section on how to contribute and how to build and run the extension in the top level README.md.

it makes sense to mention CONTRIBUTING.md in README.
