Source Setup on Windows

This will tell you how to get the Geppetto source code and build it on a Windows machine (Windows? I’m on OSX/Linux!).

Note: if you just want to play with a sample Geppetto deployment you don’t need to install anything, just visit If you want to install the latest released sample deployment just download it from here and run /bin/startup.bat. The following instructions are if you want to setup Geppetto from sources.

Prerequisite software

You need a bunch of other software to setup Geppetto from sources. The good news: You probably have some of this on your machine already!

  • Java SE Development Kit 8: Installer, you will need to make an account in order to download
  • Python 2.7: Installer
  • setuptools for Python 2.7: Installer
  • pip for Python 2.7: Installer
  • Maven: ZIP file, please follow these instructions - particularly, you have to add the bin folder to your PATH environment variable (What are environment variables? See below)
  • git: Installer, make sure to select “Use Git from the Windows Command Prompt” during the installation
  • Apache Tomcat 8: All Downloads, use the 32-bit/64-bit Windows Service Installer for Tomcat 8.
  • Virgo Server for Apache Tomcat: ZIP file, unpack it to your desired location

Environment Variables

Environment variables tell your operating system and other programs where you installed certain software. To modify them, go to the Control Panel (start menu or search for it), select System, then Advanced System Settings and click on Environment variables.

Once there, you can specify user variables (only for your account) and system variables (for everybody). Both will work for us, only JAVA_HOME should generally be a system variable.

Create variables with the following names and values, or look if they already exist:

  • JAVA_HOME: path to Java SE Development Kit 8
  • PYTHON_HOME: path to Python 2.7
  • SERVER_HOME: path to Virgo Server for Apache Tomcat
  • MVN_HOME: path to Maven

Maven needs to build with Java 8. If you want to point your JAVA_HOME variable to a different version, create a file mavenrc_pre.bat in your home directory that contains:


Next, you have to modify the PATH variable. This will allow you and Geppetto to run several programs from the command prompt. You may see that the PATH variable exists twice: Once as a user variable, once as a system variable. Use the one where the variables above belong to (and if it doesn’t exist, create it). Select it and click on edit. Append the following strings to the value field, separated by semicolons:

  • %JAVA_HOME%\bin
  • %PYTHON_HOME%\Scripts

Make sure that there is no semicolon at the end of the path variable. OK, that was everything you need, let’s get the source code now.

Setup Geppetto Repositories

First, create a directory where you want the Geppetto source code to live (geppetto-sources from here on). Open up the command prompt (cmd.exe) and navigate to it by typing:

cd geppetto-sources

Once there, clone the org.geppetto repository from GitHub by entering:

git clone

In Windows Explorer, navigate to geppetto-sources\org.geppetto\utilities\source_setup. Open the config.json file in a text editor and change the value of the sourcesdir field to the path of your source directory (use \\ as separators).

Go back to your command prompt and enter:

cd org.geppetto\utilities\source_setup

You are now in the source_setup folder, which contains some handy scripts. First, run the script:


This will copy all of the required repositories to geppetto-sources. Make sure that you have writing permissions for it. If a repository is missing, check that it is entered correctly in config.json.

Building Geppetto

To build Geppetto, navigate your command prompt back to the org.geppetto directory. You can do this simply by entering twice:

cd ..

Once there, run:

mvn -Dhttps.protocols=TLSv1.2 install

This will build all of the Geppetto modules at once. As you do development, you probably don’t want to re-build all modules if you only worked on a few ones. In this case, you can build the modules individually and then re-deploy. To build an individual module, just run the install command from its directory. To prevent problems caused by old build files, you may want to clean before reinstalling by:

mvn -Dhttps.protocols=TLSv1.2 clean install

Deploying Geppetto

To deploy Geppetto to the Virgo server, navigate your command prompt again to the source_setup directory by typing:

cd utilities\source_setup

Then run:


This will copy all of the built jars and wars over to %SERVER_HOME%\repository\usr and the geppetto.plan file in org.geppetto to %SERVER_HOME%\pickup.

Starting and Stopping Virgo

The Virgo server is started and stopped via batch scripts. Simply go to %SERVER_HOME%\bin (in Windows Explorer or through the command line) and run the startup.bat or shutdown.bat file.

For more info on Virgo’s control scripts, see here.

With that you are basically done! So, fire up the startup.bat file, wait until its output stops, cross your fingers and point your browser to:


You should now see Geppetto starting up. Good job!

The script allows you to perform git commands on all repositories at once. This makes it easier to maintain the state of the many repos required by Geppetto.

To use it, navigate your command prompt to the source_setup folder and type:

python branches

to print the current branch of each repo

python checkout <branch>

to checkout on each repo. Note the branch must exist on each repo.

python fetch [remote] [branch]

to perform git fetch on each repo

python pull [remote] [branch]

to perform git pull on each repo
