[How to use watch?] Watch command doesn't work as expected ( ingores inputs )

[ThePlenkov]

Hi! Didn't get any reaction on my post in Discord community so duplicating it here.

I am evaluating watch command. As a use case I have set up a small project to generate plantuml diagrams from puml files on the fly.

For that purpose I have defined

• a command puml accepting only *.puml files as input
• a target build using input !{workspaceRoot}/**/* and puml task as a dependency
• watch command like this: nx watch --verbose --all -- npx nx build \\$NX_PROJECT_NAME

What I expect from this script to do - I expect that watch command will watch for all files ( i don't mind ), but it will execute targets respecting their named inputs.

Unfortunately it doesn`t happen. Whenever I do anything, like creating a new file - it just runs build again and again. In a case when I use a command to build other files ( such as diagram images ) - it just runs this command many many times.

Indeed something is wrong and I'm trying to understand what - is my config bad or nx doesn't support this functionality yet.

Could you please have a look. You can just run npm run dev in my project to test it. Just try to do anything, like creation if new file, you will see that watch command fill still try to build images for every single change ignoring inputs. Thanks!
