Description

I am trying to run a Java project but the extensions don't get activated. I have JDK installed and java.home set in settings.json.

Steps to Reproduce

1. Build an image from this Dockerfile
2. Run a container and open localhost:8080
3. Open terminal and clone a repository.
4. Click on any file to get prompted with this notification

We're getting reports it works fine in other systems, might be a Firefox-specific issue since extensions also has a client-side worker working while its backend runs.

I'm getting the same error here, in firefox and chromium(74). I'm running ubuntu 16.04

I am getting the same result on Chrome too. Can you inspect the Dockerfile to see if I'm missing something? Thanks

[newk5]

Not sure if this makes a difference but I'm not using docker, I just downloaded the binary and ran it.

Having the same problem using the latest Docker image and Firefox developer edition 71.0b8:

If a web worker problem is suspected, there's an error on the JS console that seems relevant:

Failed to register/update a ServiceWorker for scope ‘https://xxxxxx/’: Bad Content-Type of ‘text/html’ received for script ‘https://xxxxxx/service-worker.js’. Must be a JavaScript MIME type.

navigating to this "service-worker.js" from within the browser, I could see it's actually an HTML page, so the complaint looks legit.

BTW my set up uses HTTPS terminated by Nginx and forwards everything to the plaintext HTTP port of coder-server, so I don't expect a problem caused by Nginx when forwarding "service-worker.js".

Same error with chrome(78) and binary running on debian 9(deepin 15)

[wjayesh]

If it helps, the codercom/code-server:2.1657-vsc1.39.2 image does not have this particular problem.
There instead, when you select run/debug from the context menu or select any Java command like "create a project" from the command palette; "Activating _Extensions" appears for a while on the status bar and there's no further activity @sr229

[sr229]

Probably need to do some investigation

From what I've seen (#1136 (comment)) the join error is because the extension is missing files. You can try:

npm install
./node_modules/.bin/gulp download_server

But we need to look into our marketplace and figure out why this is failing to fully build. At least, I think that's the source of the problem.

[code-asher]

Linked the wrong comment. Here's the right one: #1136 (comment)

[code-asher]

Huh, but if earlier images don't have the problem then the issue could be in the install phase in code-server rather than our marketplace.

[sstone1]

@code-asher I'm seeing a similar problem with ms-vscode.go - the version installed by code-server --install-extension ms-vscode.go does not have a node_modules folder, so fails to activate as one of its dependencies is missing.

Edit: looks like #1171 is open for this particular extension.

I have JDK installed and java.home set in settings.json. system env have JAVA_HOME JDK_HOME too.

code-server2.1688-vsc1.39.2-linux-x86_64.tar.gz

extensions folder no package.json so npm install will do nothing
run npm install gulp
./node_modules/.bin/gulp download_server report No gulpfile found

[sstone1]

@code-asher @sr229 is there an update on this and similar issues with files missing in extensions downloaded from the Code Server marketplace?
