Custom Maven Assembly Descriptors
Maven offers a set of predefined assembly descriptors, described below. Custom assembly descriptors can also be created, and this is the reference documentation for a custom assembly descriptor:
This is an example of a custom assembly descriptor, used to build a complex release artifact for a multi-module project:
Custom assembly descriptors are conventionally placed under src/assembly of the module that executes the plugin.
Assembly ID
The assembly ID is specified as the value of the <id> element in the assembly descriptor. The assembly ID will become the assembly artifact classifier, present between the version and the extension. The artifact will be named <project-name>-<assemblyId>.<ext>. If I just want it to be <project-name>.<ext> (or <final-name>.<ext>), do not use an <id>...</id> declaration in the assembly descriptor.
