This plugin integrates the Leiningen build system into IntelliJ IDEA.
General usage instructions
Install the plguin via the plugin manager. Then go to Settings > Leiningen and set up the location of Leiningen. Now you can run Leiningen targets in the Leiningen tool window on the right side of the IntelliJ main window by doubleclicking on the target name.
When you open a project that is having a project.clj file in it's root, it is automatically added to the list of Leiningen projects in the Leiningen tool window. If you have multiple project.clj in your project tree (e.g. a project with subprojects) you can add these manually by pressing the plus icon in the Leiningen tool window.
