@gattytto I am giving a try right now

[sunix]

@gattytto so it is missing the plugin cool2k/vscode-lombok/latest in the plugin registry right ?

[sunix]

I guess this one: eclipse-che/che-plugin-registry#761

[gattytto]

yes @sunix you can test it using this one, just edit pom.xml to use java11 instead of java8:

demo pr

[sunix]

@gattytto This looks tricky for the enduser to figure out what he needs to do to have the plugin working.
Why not making it in the same sidecar with Java extension like we do for Quarkus?

[sunix]

the other option we could try: add the volume vscode-unpack to all the java based plugin.
and add

 preferences:
      java.jdt.ls.vmargs: -javaagent:/tmp/vscode-unpacked/lombok.jar

to the lombok meta.yaml (not sure it is possible)

[gattytto]

@sunix that is a feature request

[sunix]

For a nice demo (to be included in the Get Started sample), I would add a VSCode Didact tutorial like this one:

https://www.baeldung.com/intro-to-project-lombok

[sunix]

So that works but i don't think this is the right approach. It should be done by the Che plugin (entrypoint maybe ?)

[gattytto]

@sunix maybe we can have a feature in plugins meta.yaml like "globalVolume" or "volumeForAll" to set up a folder that will be mounted in all CLI and sidecar containers (including theia's) to have files copied there. With that and settings from meta.yaml and a command in the meta.yaml that is run in the sidecar, we could have all this sorted out invisibly to the user.

I don't know about the current status of meta.yaml but it's easy to be able to just override the init command from the yaml and not having to put it in the sidecar .sh/Dockerfile.

command:
      - sh
      - -c
    args:
      - until [ -d /tmp/vscode-unpacked/*lombok* ]; do sleep 1; done; cp $(find /tmp |grep lombok |grep jar) /tmp/vscode-unpacked/; sleep infinity

I think this PR is stale now as we have added Lombok without the plugin. Let's close this PR and try again with the new approach.
