It might be necessary to customize the file name of libraries and TLD. By default, those resources are stored using the following pattern: ${artifactId}-${version}.${extension} (if the artifact has a classifier it is ${artifactId}-${version}-${classifier}.${extension} of course).
The outputFileNameMapping parameter allows you to give a custom pattern. Each token defined in the pattern will be replaced with the value for the current Artifact. You can use any property of Artifact and ArtifactHandler as a token.
For instance, to store the libraries and TLDs with no versionning, use the following pattern: ${artifactId}.${extension} .
