Class ServicesResourceTransformer

java.lang.Object

org.apache.maven.plugins.shade.resource.ServicesResourceTransformer

All Implemented Interfaces:

ResourceTransformer

public class ServicesResourceTransformer
extends java.lang.Object
implements ResourceTransformer

Resources transformer that relocates classes in META-INF/services and appends entries in META-INF/services resources into a single resource. For example, if there are several META-INF/services/org.apache.maven.project.ProjectBuilder resources spread across many JARs the individual entries will all be concatenated into a single META-INF/services/org.apache.maven.project.ProjectBuilder resource packaged into the resultant JAR produced by the shading process.
