I used to use clojure, but one of the reasons I stopped was I personally found tools like Maven cumbersome to work with. I admit that was 8 years ago or so, so there's a chance it got better, but once people are driven away by tooling issues it takes a lot to convince them to give an ecosystem another chance.

An example of this ossification of understanding is how people still think dotnet is Windows only because they stopped caring before Core/Modern dotnet became a thing
