Hi, I assume that there are several problems, e.g., the missing JCas cover classes.
I have taken the liberty to create a project based on your example like I would use ruta right now (with 2.3.1): http://people.apache.org/~pkluegl/examples/date-example.zip - the script file are in src/main/ruta - the wordlist file is in src/main/resources - the descriptors are generated to target/generated-sources/ruta - the JCas cover classes are generated to target/generated-sources/jcasgen - src/test/java contains two JUnit tests: one based on the generated descriptor and one based on uimaFIT without ae descriptor Let me know if this helps and/or you have questions about the project setup.
