Debugging `make: 'build' is up to date.`

TL;DR - Rename your directory build something else

Failure

Makefile

build:
    docker build . -t my-basic-app

Look. I have the most basic app, Dockerfile and Makefile. Why can't it just run make build command properly as I defined in Makefile?

shyamajp@ubuntu:~/Projects/my-basic-app$ make build
make: 'build' is up to date.

Debug

Let's get rid of this stupid error. At the root level, you must have a directory named build. That's why you see this unexpected behavior.

In my case, I can change outDir name from build to dist to avoid this specific conflict.
tsconfig.json

{
    "outDir": "dist"
}

Conclusion

Do not name your directory same as Makefile target. Be careful with names like build and test, which are often used for both Makefile targets and directory names.

I know this is a noob question but I've done it a few times already and I thought I might as well document it somewhere for myself. I hope this helps other newbie folks like me.
