I am looking for Java-based Less CSS compilers. On Github, I have stumbled across
Both are from the same develop
lesscss4j is a Java compiler, written with ANTLR. While this will be faster, the problem is that you need to synchronise it with the official lesscss compiler which is in javascript. This project hasn't been touched for 2 years. Lesscss-java is a wrapper around the official compiler and is running in Rhino JS engine. It used by the popular Lesscss-maven-plugin.
