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), 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 on the GitHub Releases page. Select a release, then download bob/bob.jar. If you are using Defold 1.9.6, you will need OpenJDK 21 to run it. For older versions of Defold, you will need openJDK 17 or 11.

Compatible OpenJDK 21 mirrors (from Defold 1.9.6):

If you are on Windows you want the .msi file installer for OpenJDK.

Usage

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:

clean
Delete built files in the build directory.
distclean
Delete all files in the build directory.
build
Builds all project data. Add the --archive option to build a data archive file (“game.darc” in the build directory).
bundle
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. The --variant specifies which type of executable to build when bundling and it together with the --strip-executable option replaces the --debug option. If no --variant is specified you will get a release version of the engine (stripped of symbols on Android and iOS). Setting --variant to debug and omitting --strip-executable yields the same type of executable as --debug used to do.
resolve
Resolve all external library dependencies.

Available platforms and architectures:

x86_64-darwin (Defold 1.3.5 and older)
x86_64-macos (Defold 1.3.6 and newer)
macOS 64 bit
arm64-macos (Defold 1.5.0 and older)
macOS Apple Silicon (ARM)
x86_64-win32
Windows 64 bit
x86-win32
Windows 32 bit
x86_64-linux
Linux 64 bit
x86_64-ios
iOS macOS 64 bit (iOS Simulator)
armv7-darwin (Defold 1.3.5 and older)
armv7-ios (Defold 1.3.6 and newer)
iOS with available 32-bit armv7-darwin and 64-bit arm64-darwin architectures. By default, --architectures argument value is armv7-darwin,arm64-darwin.
armv7-android
Android with available 32 bit armv7-android and 64 bit arm64-android architectures. By default, --architectures argument value is armv7-android,arm64-android.
js-web
HTML5 with available js-web and wasm-web architectures. By default, --architectures argument value is js-web,wasm-web.

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
100%
$

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 a macOS application (named My Game.app):

$ java -jar bob.jar --archive --platform x86-darwin resolve distclean build bundle
100%
$ ls -al build/default/
