The Application Assembler Plugin is a Maven plugin for generating scripts for starting java applications. All dependencies and the artifact of the project itself are placed in a generated Maven repository in a defined assemble directory. All artifacts (dependencies + the artifact from the project) are added to the classpath in the generated bin scripts.
