Feature Model Launcher

The Feature Model Launcher can launch an feature model application file to a running process.

The launcher can be executed as follows:

java org.apache.sling.feature.launcher.impl.Main

or via the Java Main class of the jar file:

java -jar org.apache.sling.feature.launcher.jar

The following command line options are supported:

java -jar org.apache.sling.feature.launcher.jar -h
usage: launcher
 -C <arg>    Set artifact clash override
 -CC <arg>   Set config clash override
 -c <arg>    Set cache dir
 -D <arg>    Set framework properties
 -f <arg>    Set feature files (relative and absolute file path or URL including classloader resources)
 -i <arg>    Set the id for the launch feature
 -p <arg>    Set home dir
 -u <arg>    Set repository url
 -V <arg>    Set variable value
 -ec <arg>   Set Extension Configuration (format: extensionName:key1=val1,key2=val2)
 -fv <arg>   Set Felix Framework version
 -fa <arg>   Set Framework Artifact (overrides felix framework version)
 -v          Verbose

Cache

The launcher creates a local cache, by default in a subdirectory called launcher. If you want to run the launcher with a clean start, delete this directory before invoking the launcher.

rm -rf launcher && java -jar org.apache.sling.feature.launcher.jar -h

Feature Files as Classloader Resources

Note: if feature files are provided as a Classloader Resource like in an executable JAR file or classpath resource then it's Resource URL can be handed over to the Launcher as feature file (-f option):

java.net.URL url = getClass().getResource("/my-feature-file.json");
String[] arguments = new String[] {
    "-f", url.toString()
};
org.apache.sling.feature.launcher.impl.Main.main(arguments);
