The problem in my experience is you invest time learning build system A, then a year later build system B comes out, and not only do you need to relearn a bunch of stuff again, often build system B does some of the stuff of system A but not all of it, plus it does new stuff that you've never encountered before. Then this cycle repeats, endlessly, and every new team you join has adopted the newest build system.
Granted some ecosystems are worse than others here. in the JavaScript world it went something like: make/grunt/bower, gulp/webpack, esbuild, parcel, vite, rollup, and on and on it goes.
Even in the conservative Java ecosystem we've been through maven, ant, groovy/gradle...
Most of these tools offer incremental improvements for a huge learning cost. It's a nightmare.
