Bazel Support

[doug-ol]

vscode-java does not recognize bazel as a build environment

Environment

• Operating System:
• JDK version:
• Visual Studio Code version:
• Java extension version:

Steps To Reproduce

1. Load a java project with bazel as the build system (example)
2. Navigate to any .java file

Current Result

Receive "Classpath is incomplete" warning

Expected Result

vscode-java to infer classpath from bazel

Seems like this work would be related to eclipse-jdtls/eclipse.jdt.ls#543

I would also love to see this supported.

[neakor]

I would love to get this support as well please!

After tinkering for hours, I have not yet been able to get vscode to launch & debug my java+bazel project. I can run in console no problem, but I also love this request to get bazel fully supported in vscode-java.

Its very painful to work in a monorepo with vscode without this.

A thought on how to implement this. We could reuse the JDT extension bundle from salesforce/bazel-eclipse. Not sure on the best route for repackaging this for VSCode and making sure that the project is credited though.

Interesting. I spent Friday noodling with the intellij plugin, slicing out the intellij-ide-info.txt generation piece into something I could reuse. I ended up with something super hacky, which for example lifts the test code into the generator to allow injection of bits of the parsing code using intellij's dependency injection framework. From there I then generated a json snippet that can be copied-n-pasted into settings.json. Hack-city!

I could share that if people thought it useful, but it lacks a certain panache, shall we say.

I filed an issue with the bazel-IntelliJ people to see if they were enthused, but they weren't particularly, which is fair enough:

bazelbuild/intellij#1827

Love it, I see your hacky plugin and raise you this hacky bash script that I'm using as a workaround

Oh, you made a project and classpath. Maybe that's a better idea. OK when I get time I'm going to put my hacktasticness up on github and maybe try to dehack a little bit, and try to see if our bazel-intellij friends like the idea.

[Jonpez2]

Well now. I just found this thing, and I made it work with an hour's noodling, and now I have the javas with the bazels with the vscodes. All I had to do was to fix the distribution I was getting natively for my code-server setup, which didn't have the platform-specific stuff. But this is way less overhead for a bazel setup, and I bet the 'real' vscode install works fine... https://github.com/georgewfraser/java-language-server

Some update may link with #1825. Any plan to make javaBuildFilePatterns including BUILD and WORKSPACE default?

[jalilalchy]

Beyond adding regex patterns to javaBuildFilePatterns, would any additional work be needed?

[jalilalchy]

Please advise.

We have a Bazel VSCode Java Extension at https://github.com/salesforce/bazel-vscode-java. It adds Java support for Bazel projects to VS Code based on RedHat's Java extension.

The Bazel Language Server (and the Bazel Eclipse Feature) received a significant overhaul. This update needs to be brought into the VS Code extension. Any contributions are highly appreciated. The language server can be fetched from https://opensource.salesforce.com/bazel-eclipse/latest/
