This article covers a Bloomreach Experience Manager version 13. There's an updated version available that covers our most recent release.

Build Bloomreach Experience Manager From Source



Build any Bloomreach Experience Manager Developer Edition open source project from source.


BloomReach provides all Bloomreach Experience Manager Developer Edition releases as open source to the community. Anyone can rebuild any project that is part of a Bloomreach Experience Manager Developer Edition release from source and, if they wish, fork and modify it. The latter is very useful, for example, in case a developer wants to fix a bug or implement an improvement to be provided to the community as a patch.

Project Structure and Prerequisites

The Bloomreach Experience Manager project has been split into a number of Maven projects. This allows separate release cycles and reduces the amount of code that will be rebuilt when only working on a sub-project.

You need to have the following installed to be able to build all Bloomreach Experience Manager components:

Build an Archetype Release Tag from Source

$ git clone
$ cd hippo-project-archetype
$ git checkout hippo-project-archetype-13.4.22
$ mvn clean install

This will build the archetype, which features a pre-built installed Bloomreach Experience Manager implementation project in its target directory with based on the relevant release. To start it:

$ cd main/target/gettingstarted
$ mvn -P

Build a Core Bloomreach Experience Manager Open Source Project Release Tag from Source

Depending on the project or projects you wish to work on, you can download the source code from the following locations:

You can use Git to clone one or all of the following source repositories:

These are only the main projects. For the full list of projects see

Bloomreach only provides the Git trees for the release tags of Bloomreach Experience Manager. Code changes which are under development for major, minor, or maintenance releases are not synchronized to the public community Git repositories. To find the tag of a project for a specific Bloomreach Experience Manager release inspect the Bloomreach Experience Manager release POM you are using (this is either the parent POM of your project in the case you using Bloomreach Experience Manager, or the grandparent POM of your project in case you are using Bloomreach Experience Manager) and check the version of the project you are using (you can also find this out by running mvn dependency:tree in your project).

$ git clone
$ cd hippo-repository
$ git checkout hippo-repository-5.2.0
$ mvn clean install -DskipTests

Modify a Bloomreach Experience Manager Project

If you want to make modifications to a project, create a fork branch from the relevant tag.

Clone the repository of the project you want to modify, for example, hippo-repository

$ git clone

Create a new local fork development branch based on the release you want to modify, for example. 5.3.0:

$ cd hippo-repository
$ git checkout -b forked-5.2.0 hippo-repository-5.2.0

Update the POM versions of your forked project:

$ mvn release:update-versions -DautoVersionSubmodules -DdevelopmentVersion=5.2.0-forked-SNAPSHOT

You are now ready to make modifications to the source code.

Once you have made the modifications, build the project with the following Maven command:

$ mvn clean install

To test your modifications in the gettingstarted project, override the version property for the project you modified in the gettingstarted project's root pom.xml:


Then rebuild the gettingstarted project:

$ mvn clean verify

Use JRebel

If you have JRebel installed, you can speed up this development cycle using JRebel.

Simply build the core projects with JRebel switch enabled:

$ mvn -DskipTests -Djrebel clean install

And build the gettingstarted project as before, but start it also with the JRebel switch enabled:

$ mvn -Djrebel

Frontend Development

For instructions on how to develop the CMS frontend with automated builds see the README in the relevant projects/modules.
