Taking out Netflix’s gradle-lint-plugin for a spin

Dependency management is a complex thing. A typical gradle project has several dependencies, each of which in turn has multiple other dependencies and so on. This continues and what forms as a result is called a dependency graph. While this is great, unused dependencies is a big problem. For instance, say your project depends on dependency A which then depends on B, C and D. Your project also depends directly with another dependency E which in turn depends on F and G. The dependency graph would look something like this:

Your Project -> A -> (B, C, D)
Your Project -> E -> (F, G)

Now, your project probably only uses code in A which only then directly depends on some code in B. Also, maybe you also have some code that depends on E but that code in E doesn’t depend directly on neither F, nor G. This means that C, D, F and G are your unused dependencies. Continue reading
