@Flodding update your MapTools and it should fix it, as the Spigot API changed somewhere around Sep/2015. If it doesn't work, try modifying the Spigot API version in pom.xml as in PR #5 and compile again (you'll need maven and openjdk-7-jdk) running the following command from the project folder:

mvn clean install

The resulting jar will be located under ./target/maptools-0.0.1-SNAPSHOT.jar
Hope this helps you :)
