Install Bazel for Golang build applications in VScode - go

Question

How to install bazel for golang application building in VScode?

Answer 1

There is no direct support for Bazel yet, as per golang/go issue 37205 ("x/tools/gopls: support for bazel-based projects")
bazelbuild/rules_go wiki/Editor-and-tool-integration has a design document for building editor and tool integration: a new gopackagesdriver binary that integrates Bazel+rules_go with golang.org/x/tools/go/packages.
But it is not fully implemented yet (Q1 2022).
In the meantime, you can follow Bazel IDE setup, which involves:
Create a launcher script, say tools/gopackagesdriver.sh:
#!/usr/bin/env bash
exec bazel run -- #io_bazel_rules_go//go/tools/gopackagesdriver "${#}"
adding in the .vscode/settings.json of your workspace:
{
"go.goroot": "${workspaceFolder}/bazel-${workspaceFolderBasename}/external/go_sdk",
"go.toolsEnvVars": {
"GOPACKAGESDRIVER": "${workspaceFolder}/tools/gopackagesdriver.sh"
},

"references": false,
"runtest": false
