LanguageTool 1.9 is the first version to be available as a Maven artifact on Maven Central. This makes it easy for Java developers to integrate LanguageTool into their own applications. We’re planning to split it up into several artifacts in the future, so you don’t have to get that one large jar (46MB) if you don’t need support for all languages.
For now, you can get the artifact at http://bit.ly/T5EkvO
