This project provides the core functionality of openLCA as a set of Maven modules. Since version version 1.4 the openLCA application is built on top of these components.

In order to install the modules, you need to have a JDK >=17 and Maven 3 installed. Download the repository (or get it via git), navigate to the root folder and type the following command in your console:

cd  olca-modules
mvn install

This will build the modules from source and install them into your local Maven repository. If the build fails because of failing tests you can skip the tests via:

mvn install -DskipTests=true
