 23. The dependencies that should be excluded when analyzing the licenses, this is useful when you declare the dependencies in `pom.xml` with `compile` scope but don't distribute them in package. (Note that non-`compile` scope dependencies are automatically excluded so you don't need to put them here).
 24. The transitive dependencies brought by <23> should be recursively excluded when analyzing the licenses, currently only maven project supports this.
