Go fails to compile as compiler is not launched in proper directory

[jcowgar]

I have a simple hello world program. When attempting to debug, I receive the error:

DAP server listening at: 127.0.0.1:34191
‌​Build Error: go build -o /home/jeremy/projects/hello_world/__debug_bin -gcflags all=-N -l /home/jeremy/projects/hello_world/cmd/tools/hello_world
go: go.mod file not found in current directory or any parent directory; see 'go help modules' (exit status 1)
Failed to launch: Build error: Check the debug console for details.‌​​​​​​​
Debugging ended

go.mod does exist in /home/jeremy/projects/hello_world. When I go to that directory in my terminal and run the "go build" command above, a binary is built successfully.

[~/projects/hello_world]
jeremy-> go build -o /home/jeremy/projects/hello_world/__debug_bin -gcflags "all=-N -l" /home/jeremy/projects/hello_world/cmd/tools/hello_world

[~/projects/hello_world]
jeremy-> ls -lah __debug_bin
-rwxr-xr-x 1 jeremy jeremy 1.8M Sep 15 07:39 __debug_bin

My sublime-project is

{
    "folders": [
        {
            "path": ".",
        }
    ],
    "debugger_configurations": [
        {
            "name": "Debug Hello World",
            "type": "go",
            "request": "launch",
            "output": "${project_path}/__debug_bin",
            "program": "${project_path}/cmd/tools/hello_world",
            "cwd": "${project_path}"
        },
    ],
}

Same problem here.

Try setting dlvCwd listed here https://pkg.go.dev/github.com/go-delve/delve/service/dap#LaunchConfig

// DlvCwd is the new working directory for Delve server.
// If specified, the server will change its working
// directory to the specified directory using os.Chdir.
// Any other launch attributes with relative paths interpreted
// using Delve's working directory will use this new directory.
// When Delve needs to build the program (in debug/test modes),
// it will run the go command from this directory as well.
//
// If a relative path is provided as DlvCwd, it will be
// interpreted as a path relative to Delve's current working
// directory.
DlvCwd string `json:"dlvCwd,omitempty"`

That worked, thank you!

Thank you for that! It works!
