wtf is kotlin-eclipse?

This project, kotlin-eclipse, brings Kotlin language support to the Eclipse IDE. If you write code in Eclipse and want to use Kotlin, this plugin adds syntax highlighting, error checking, and other language features to make that experience smoother. Kotlin is a programming language that runs on the Java platform, and this plugin lets developers use it in Eclipse. The plugin itself is built using Kotlin, so there's a bit of a setup process to get the development environment running. You need Eclipse, the AspectJ plugin for handling code weaving (a technique that lets the plugin integrate with Eclipse's internals), and an existing version of the Kotlin plugin to build the project. The README walks through installing these dependencies and launching a test instance of Eclipse with the plugin loaded. This project would appeal to developers who want to contribute to Kotlin tooling or need Eclipse-based Kotlin support for their workflow. JetBrains, the company behind Kotlin, maintains the language, and this plugin helps extend its reach into the Eclipse ecosystem. The README doesn't go into detail on user-facing features, so it's mainly aimed at people who want to build or contribute to the plugin rather than end users looking for installation instructions. One notable aspect is the setup complexity. Because the plugin uses AspectJ weaving to hook into Eclipse's core functionality, developers need specific tooling just to work on the project. The build can also run from the command line using Maven, which gives contributors some flexibility. The project targets Eclipse Luna SR2 (4.4.2), an older version, which may reflect when the README was last updated.
