Add support for specifying the classifier for maven dependencies

[heshanpadmasiri]

Description:
In the current implementation we can't handle cases where a given maven dependency may have more than one jar file. For example if we give the dependency for javacpp as fallows

[[platform.java11.dependency]]
groupId = "org.bytedeco"
artifactId = "javacpp"
version = "1.5.5"

it will only download and add to the final build only javacpp-1.5.5.jar not the other jar files such as javacpp-1.5.5-android-arm.jar listed under that dependency using different classifiers.
