Apache TomEE is built with Apache Maven >= 3.6.3 and Java 11. The Contribute to TomEE section from the official website for a complete Git, Github, Build, Test, and Continuous Integration details.
If you only like to compile all classes and package up TomEE without running tests then you can use the following build options
mvn -Pquick -Dsurefire.useFile=false -DdisableXmlReport=true -DuniqueVersion=false -ff -Dassemble -DskipTests -DfailIfNoTests=false clean install
This will run all the tests. We have thousands of tests and you should go out to grab a bite in the meantime.
mvn clean install
If you intend building in environments where multicast is not allowed then build with:
mvn clean install -DskipMulticastTests=true
Full build that execute arquillian test on all TomEE distributions:
mvn clean install -Pall-adapters
This will only build a module and the modules using it as a dependency.
To build just TomEE distribution execute:
mvn clean install -pl tomee/apache-tomee -am -Dmaven.test.skip=true
TomEE zip/tar.gz will be in tomee/apache-tomee/target
To build TomEE Embedded to be able to develop with its maven plugin execute:
mvn clean install -pl maven/tomee-embedded-maven-plugin -am -Dmaven.test.skip=true
