It would be nice if flags such as ‘-notimestamp’ provided by javadoc were supported in the javadoc task/DSL. Similarly GroovyDoc has recently added ‘-notimestamp’ and ‘-noversionstamp’ flags (not yet released). It would be good if there was specific support for these (or a way to handle any flags in a generic way). Looking at the javadoc command-line help, there are numerous other flags that don’t seem to be supported by the Javadoc task or within MinimalJavadocOptions.
OK, possibly StandardJavadocDocletOptions handles the Javadoc side of things. Still exploring how to use the above and whether the Groovy side can be handled.
