public class PropertiesLauncher extends Launcher
Launcher for archives with user-configured classpath and main class through a properties file.

Looks in various places for a properties file to extract loader settings, defaulting to loader.properties either on the current classpath or in the current working directory. The name of the properties file can be changed by setting a System property loader.config.name (e.g. -Dloader.config.name=my will look for my.properties. If that file doesn't exist then tries loader.config.location (with allowed prefixes classpath: and file: or any valid URL). Once that file is located turns it into Properties and extracts optional values (which can also be provided overridden as System properties in case the file doesn't exist):

  • loader.path: a comma-separated list of directories (containing file resources and/or nested archives in *.jar or *.zip or archives) or archives to append to the classpath. BOOT-INF/classes,BOOT-INF/lib in the application archive are always used
  • loader.main: the main method to delegate execution to once the class loader is set up. No default, but will fall back to looking for a Start-Class in a MANIFEST.MF, if there is one in ${loader.home}/META-INF.
