Hi Oscar, Have you noticed https://github.com/javacc/ ? It looks like a fork of the old JavaCC but with updates for Java 8. https://search.maven.org/artifact/org.javacc.generator/java/8.0.1/jar and https://search.maven.org/artifact/org.javacc.plugin/javacc-maven-plugin/3.0.3/maven-plugin have been released last April.
