- Gradle task to execute "packageDist"
- this will create *.tar.gz and *.zip archive
- with legacy file name convention
- archive is created in build/distributions
- for the libbuild J7Zip-modified.jar use fallback as file dependency in lib
as Gradle/Groovy use internal just the classes from subprojects with result
that in above no jar is included in lib but a bunch of *.class files
- added also the option to publish J7Zip-modified.jar to mavenLocal() repo.
