Gitpod: No delegateCommandHandler for vscode.java.startDebugSession when starting

Created on 20 Dec 2019 · 17Comments · Source: gitpod-io/gitpod

Describe the bug
No run links on Java source code. Running the project results in an error dialog "No delegateCommandHandler for vscode.java.startDebugSession". Apparently this would be fixed with a new version of https://github.com/microsoft/vscode-java-debug.

To Reproduce
Open any Java project, e.g. https://gitpod.io/#https://github.com/spring-projects/spring-petclinic

Expected behavior
Tests and main classes have"Run" links. Debug->Start Debugging should run the main class.

Additional Information

@dsyer We will update Gitpod to latest java support. For time being you can upload latest version of extensions into your repo to enable them, see https://www.gitpod.io/docs/vscode-extensions/#installing-an-extension

Duplicate of https://github.com/gitpod-io/gitpod/issues/886

Thanks for the link. Actually I’m not sure I know where to get a .vsix file from (also drag and drop is rubbish for anyone without a file explorer). Normally I just click on the “Install” button. Why can’t Gitpod do it the normal way? Where do you find those files?

@dsyer yes, it is not very convenient right now :( Unfortunately MS does not let us to access VS Code marketplace: https://www.gitpod.io/docs/vscode-extensions/#where-do-i-find-extensions We are working on the open marketplace which will be hosted under Eclipse Foundation:

Thanks. Found it. Unfortunately it doesn't seem to fix anything. How do I know if that extension is active?

@dsyer It should be like that:

You need to reload the page to enabled latest versions. I've opened a bug in Theia to make it work automatically in the future: https://github.com/eclipse-theia/theia/issues/6777

OK now I have this in .gitpod.yml:

vscode:
  extensions:
    - [email protected]:LRImBn//d5JhH4PUEI1BaQ==
    - [email protected]:3ARqL3kPh1J1SwpVjYUjqw==
    - [email protected]:BlvjRRJyZszeJzIS+xEHIA==

The first one is supposed to be a collection of extensions that include the rest, but using it on its own didn't seem to work at all.

I was able to run the app. But I get this on the tests:

Error: 'org.eclipse.jdt.core.IJavaProject org.eclipse.jdt.ls.core.internal.ProjectUtils.getJavaProject(java.lang.String)'.Error: 'org.eclipse.jdt.core.IJavaProject org.eclipse.jdt.ls.core.internal.ProjectUtils.getJavaProject(java.lang.String)'.Error: 'org.eclipse.jdt.core.IJavaProject org.eclipse.jdt.ls.core.internal.ProjectUtils.getJavaProject(java.lang.String)'.Error: 'org.eclipse.jdt.core.IJavaProject org.eclipse.jdt.ls.core.internal.ProjectUtils.getJavaProject(java.lang.String)'.Error: 'org.eclipse.jdt.core.IJavaProject org.eclipse.jdt.ls.core.internal.ProjectUtils.getJavaProject(java.lang.String)'.Error: 'org.eclipse.jdt.core.IJavaProject org.eclipse.jdt.ls.core.internal.ProjectUtils.getJavaProject(java.lang.String)'.

Nothing very helpful there.

Got it working almost:

vscode:
  extensions:
    - [email protected]:LRImBn//d5JhH4PUEI1BaQ==
    - [email protected]:3ARqL3kPh1J1SwpVjYUjqw==
    - [email protected]:BlvjRRJyZszeJzIS+xEHIA==
    - [email protected]:Q60n5quUtfd1EcwzkRq96A==
    - [email protected]:gdyOPlzH3PU5IkrigIg85g==

(Adding more extensions from the vscode-java-pack manually.)

The next thing that breaks is that when the tests run you don't get feedback about whether it was successful or not, just a placeholder (see screenshot).

Also, when you run the app there is no way to stop it (usually in vscode there is a little floating dialog with play/stop/refresh type buttons).

@dsyer please replace .gitpod.yml with and reload:

vscode:
  extensions:
    - [email protected]:3ARqL3kPh1J1SwpVjYUjqw==
    - [email protected]:Q60n5quUtfd1EcwzkRq96A==
    - [email protected]:BlvjRRJyZszeJzIS+xEHIA==

I don't see that redhat.java is updated to latest in your gitpod.yml. The bug was in this extension. You should also see in the extension view that a version of redhat.java is correct.

For me app and test running work with such configuration:

In Theia, it is always docked in the debug view.

Could you elaborate on it? How does it look in VS Code? I see test in the test view, for instance:

Got it thanks. Finding it hard to figure out how to force Gitpod to close and reopen the workspace. Is there an action for that?

I also found that I need the Maven extension, otherwise the run/debug links are not rendered.

Your screenshot shows the $(check) placeholder on the test (should be a "tick" or "cross" to indicate success or failure).

In the top right corner there is your account icon, if you click on it then you can stop the workspace or open the dashboard from there:
