Building Modpacks

Get the .jar from the launcher-builder/build/libs/ folder.

java -jar launcher-builder-X.Y.Z-SNAPSHOT.jar
    --version "pick_a_version"
    --input .
    --output upload
    --manifest-dest "upload/your_modpack.json"

"version" is the version of your modpack and it doesn't have to be a number -- whenever you want to push an update, you have to change the version code to anything else that has never been used before
"input" is the folder with "loaders," "src," and "modpack.json" -- . means "the current folder"
"output" is the folder to put the output
"manifest-dest" is the manifest file that is generated

There should be a upload/ folder now with the generated files.

Deploying the Server

See Deploying Server Modpacks.

Generating a Package Listing

There is no command line tool to do this. However, the format of packages.json is pretty simple so you should be able to generate it yourself easily.
