Incoherent behaviour with doc of spring-boot:run mojo when dealing with target/classes

[tdemande]

Documentation about the run mojo of the spring-boot plugin (http://docs.spring.io/spring-boot/docs/1.1.5.RELEASE/maven-plugin/run-mojo.html), for the addResources parameter, states that resources will be included twice if the parameter is set to true ("Since resources will be added directly, and via the target/classes folder they will appear twice if ClassLoader.getResources() is called."). In practice, resources present both in their source directory and in target/classes will have their target/classes file deleted (see https://github.com/spring-projects/spring-boot/blob/master/spring-boot-tools/spring-boot-maven-plugin/src/main/java/org/springframework/boot/maven/RunMojo.java#L263).

I can understand the need for removal of target/classes content (although this is a bit disturbing), but then it should be stated explicitly in the parameter description.
