tasks contributed by VS Code extensions don't work

[akosyakov]

They look bogus:

And cannot be executed:

You can reproduce it with grunt & gulp VS Code built-in extensions.

@elaihau What I do for now to try built-in VS Code extensions, for example for grunt:

• clone and install this extension https://github.com/theia-ide/vscode-builtin-extensions somewhere
• after that copy vscode-builtin-extensions/vscode/extensions/grunt to theia/plugins
• then start Theia, grunt VS Code extension should be installed, check plugins View
• you can debug source code of this extension with Hosted Plugin: Debug Instance command

Particularly for grunt you will need to study how to work with it, I've created an example project with from grunt-init-node. After you have it, you should compare experience in Theia and VS Code. VS Code users should not be lost. You can also find some articles for working with grunt in VS Code and try to follow along them with Theia.

Thank you @akosyakov !

I followed the instructions to have the grunt extension built, copied to theia/plugins, and shown up in the plugins view.

With a project, where the grunt tasks are defined, opened in theia, I was able to see similar items from 'Run Tasks'.

For people interested in reproducing what Anton did:

• clone and install this extension https://github.com/theia-ide/vscode-builtin-extensions somewhere

1. To get the code, run the following commands

$ git clone https://github.com/theia-ide/vscode-builtin-extensions.git
$ cd vscode-builtin-extensions
$ git submodule init
$ git submodule update

2. install all the dependencies https://github.com/Microsoft/vscode/wiki/How-to-Contribute#prerequisites
3. run yarn from vscode-builtin-extensions

• you can debug source code of this extension with Hosted Plugin: Debug Instance command

and from this github issue we can find more details on how to debug the theia plugins & vscode extensions: #3251

I've just tried grunt extension with grunt init example within #4714 and it does not detect tasks at all.

Updated: I got it working after reloading browse several times, it seems there are still some lifecycle issues.

[elaihau]

tasks contributed by npm, grunt, gulp, jake, typescript-language-features now work in theia.

could we close this issue if i am not missing anything ?
