在项目中构建所有go软件包

I am making a Go project containing a few packages. Those are data structures (and there will be algorithms as well). My project root looks like this:

C:.
├───array
├───binary_tree
├───heap
└───list

The thing is, I want to add like a CI. So I would have a job checking if all packages build and if all tests pass.

Unfortunately, I can't run go build on project root. I have to pass whole path to it. I mean I could write a script which calls go build X/Y/foo and then go build X/Y/bar, but the CI on GitLab (docker image) won't have those paths, it will just git clone my repo and that's it (cuz I cannot run it on a relative path from project root, but a relative path from GOPATH, so like github.com/dabljues/project_name/array). And what about the test?

So the question there would be: Can I somehow run go build and go test for all the packages in the Go project? (located in separate folders)

Use a Makefile. Define the targets and instruction to compile them.

For example define the following in a Makefile

build:
    go build -o bin/main main.go

run:
    go run main.go

To run just invoke : make build
