More precisely, within vscode when doing Run Extension it executes:

yarn run v1.22.5
warning package.json: No license field
$ webpack --watch --config ./build/node-extension.webpack.config.js
asset extension.js 2.92 KiB [compared for emit] (name: main) 1 related asset
./src/extension.ts 1.43 KiB [built] [code generated]
external "vscode" 42 bytes [built] [code generated]
webpack 5.15.0 compiled successfully in 1836 ms

but then does not actually open the VS Code Extension Development Host.

[barik]

Should it be npm:test-compile in launch.json for "preLaunchTask"?

[tomchen]

Yeah. Same problem here.

I guess tsl-problem-matcher is incompatible with webpack 5 (eamodio/vscode-tsl-problem-matcher#4, eamodio/vscode-tsl-problem-matcher#5).

As a temporary solution, you could:

in .vscode/tasks.json, change

"problemMatcher": [
	"$ts-webpack-watch",
	"$tslint-webpack-watch"
],

to

"problemMatcher": "$tsc-watch",

in package.json, change

"watch": "webpack --watch --config ./build/node-extension.webpack.config.js",

to

"watch": "tsc -watch -p ./",

Now the scripts watch and test-watch do exactly the same thing. So, if you want, you could also get rid of one of them completely and use the other one.

I see the same.
Webpack finishes with message:
webpack 5.18.0 compiled successfully in 1619 ms

@eamodio Can you help by updating the extension? PR eamodio/vscode-tsl-problem-matcher#5 is there but it seem the pattern needs to be improved further

[eamodio]

I've been holding off on further updates because of this discussion webpack/webpack-cli#2374. But I'll see what I can do with the messages we have now.

[FuPeiJiang]

for the time being, use [email protected]
or
in node-extension.webpack.config.js

  infrastructureLogging: {
    level: 'log',
  },

refs: webpack/webpack-cli#2206 (comment)
https://webpack.js.org/configuration/other-options/#infrastructurelogging

[aeschli]

@eamodio Any updates? I can't leave it broken...

[eamodio]

Will get it fixed today, though with webpack cli later than 4.2 you'll need a flag (until I can get changes landed)

[eamodio]

@aeschli I published a new version of the problem matchers (0.4.0). Although with webpack-cli > 4.2 we'll need to add this to the webpack.config.js to get it work properly.

 infrastructureLogging: {
    level: 'log',
  },`

Although, even with that change, I see the problem matcher match error, but I am not seeing F5 being blocked. But I don't think that is because of the matcher -- I feel like it has to do with the terminal changes & tasks.

I will talk to @Tyriar tomorrow about it.

[aeschli]

Thanks @eamodio, the new version works!

I believe that eamodio/vscode-tsl-problem-matcher#9 solves the remaining issue, which was that errors or success would not get caught during a re-compilation as shown at eamodio/vscode-tsl-problem-matcher#9 (comment).
