Your -swarm.jar`s now support basic command-line options to make on-the-go changes easier. In the event you’re already using `org.wildfly.swarm.Swarm as your main entry-point (or otherwise haven’t specified a main(…​)), you can see what’s available by

If you have a custom main(…​), just start passing your String…​args to the constructor of Swarm (or Container) and your application will gain access to things like -D, -c and -b among others.

On the heels of the CLI support above, which gives you the ability to pass a standalone.xml using the -c option, WildFly Swarm now also supports passing a partial standalone.xml. Previously, you had to decide if you were using standalone.xml or configuration through the Java API.

Now, if you pass a standalone.xml, its configuration will win, but anything not configured through XML can still be configured through the normal Java API, or through the defaults provided by WildFly Swarm fractions.

SwarmTool provides a command-line tool for turning an existing WAR into a -swarm.jar without requiring Maven or Gradle, only Java. For installation and usage instructions, see the User’s Guide.
