Thanks Michael. I did add all the 4 modules to my classpath like this:
java \
-cp
$CWD/demo/build/classes/java/main:$CWD/analysis/common/build/classes/java/main:$CWD/queryparser/build/classes/java/main:$CWD/core/build/classes/java/main
\
org.apache.lucene.demo.IndexFiles \
-docs $DOCS_DIR
but get this error:
Indexing to directory 'index'...
Exception in thread "main" java.lang.LinkageError:

... 6 more
the full classpath is usually very long as it will contain not only lucene
but also all the 3rd party dependencies.
