Bob the builder

Bob is a command line tool for building Defold projects outside of the normal editor workflow.

Bob is able to build data (corresponding to the build step of selecting the editor menu item Project ▸ Build And Launch), create data archives and create standalone, distributable application bundles (corresponding to the editor menu item Project ▸ Bundle ▸ … options)

Bob is distributed as a Java JAR archive containing everything needed to build. You find the latest bob.jar distribution at http://d.defold.com. Select a release, then download bob/bob.jar. To run the Bob tool, you need Java 8 installed on your computer. You can download a version of Java from https://www.java.com.


Bob is run from a shell or from the command line by invoking java (or java.exe on Windows) and providing the bob java archive as argument:

$ java -jar bob.jar --help

Available commands:

Delete built files in the build directory.
Delete all files in the build directory.
Builds all project data. Add the “–archive” option to build a data archive file (“game.darc” in the build directory).
Creates a platform specific application bundle. Bundling requires that a built archive is present (build with the --archive option) and that a target platform is specified (with the --platform option). Bob creates the bundle in the output directory unless a different directory is specified with the --bundle-output option. The bundle is named according to the project name setting in game.project.
Resolve all external library dependencies.

Available platforms:

Mac OSX 64 bit

By default, Bob looks in the current directory for a project to build. If you change the current dir to a Defold project and invoke bob, it builds the data for the project in the default output directory build/default.

$ cd /Applications/Defold-beta/branches/14/4/main
$ java -jar bob.jar

You can string commands together to perform a sequence of tasks in one go. The following example resolves libraries, wipes the build directory, builds archive data and bundles an OSX application (named My Game.app):

$ java -jar bob.jar --archive --platform x86-darwin resolve distclean build bundle
$ ls -al build/default/
