Releases of Property Binder are synced to the central Maven repository. Declare a dependency element in your POM like so:
... <dependencies> ... <dependency> <groupId>com.pholser</groupId> <artifactId>property-binder</artifactId> <version>4.0</version> </dependency> ... </dependencies> ...
If you're not using Maven, you can still download the newer releases from the Maven repository manually, here.
