use pom.properties instead of an ant-maven plugin for identifying current component.

the api needs to give the components dependencies to the client.
It is now provided by a file in META-INF/maven/<groupid>/<artifactid>/dependencies.txt
it also needs to give the current component GAV in the dependencies api to include itself.
Today the dependencies.txt is filled with the current component GAV using the maven-antrun-plugin that can be found in the parent pom.
But the information is already present in generated file META-INF/maven/<groupid>/<artifactid>/pom.properties.
So instead of using the ant plugin the API should be able to get the info from the pom.properties.
