Lathe: A Java Language Server That Works Straight From Your Maven Build

I have written Java in many editors and IDEs over the years, and they all seem to struggle with the same thing.

For me, the hard part of a Java IDE or language server was never the code intelligence. It was getting the project structure right. The IDE reads your build files and then tries to guess the module structure from them. And over time, Java’s compiler and runtime configuration has become more and more complex: annotation processors, the module system, and more. So you often end up in a familiar place: the code compiles and runs in the build, but not in the IDE. Even the best ones tend to break the project setup after an upgrade.
