TomEE is on Github at . The sources are synchronized by Apache on Github but Pull/Requests are integrated with Apache Infrastructure which means you can just submit us a patch as you would do on any Github project and Apache takes care of the rest of the process.

Apache Git

TomEE is using Git as source content manager.

The master sources are on and you can clone them using the following command:

git clone tomee-master

If you are interested in 1.7.x branch only just checkout the tomee-1.7.x branch:

git clone -b tomee-1.7.x tomee-1.7.x

Master branch is the more up to date version of the codebase and currently targets TomEE 7.x branch.


TomEE is a standard Maven project and to build it you just have to use the following command:

mvn clean install
you can need to tune your environment variable MAVEN_OPTS, a commonly use value is -Xmx1536m -XX:PermSize=64m -XX:MaxPermSize=384m
if you are interested in testing arquillian tests with all adapters of tomee you will need to activate the dedicated profile: -Pall-adapters.

Fast build

Here are some shortcut builds if you just want to create a specific artifact (note it skips tests but removing -DskipTests you will execute them):

  • TomEE zip/tar.gz:

mvn clean install -DskipTests -pl tomee/apache-tomee -am

Then TomEE archives are at tomee/apache/tomee/target/apache-tomee-${classifier}-${version}.${extension}.

Continuous Integration

TomEE is using Buildbot for its continuous integration. You can access main builds (Ubuntu ones) at these address:
