Developer Section

This part of the Apache PLC4X dedicated to provide information to people wanting to build PLC4X and hopefully also start contributing to this awesome project.

Getting Started

We have tried to make the PLC4X build experience as smooth as possible and have tried to reduce the number of required third party tools to an absolute minimum.

The full PLC4X build however builds not only Java libraries, but also C++, Python and C# libraries as well as builds Docker images on Linux, Mac and Windows.

As a start, you will basically need a Java VM of at least Java 11.

Using the Maven-Wrapper you don’t even need a Maven installation. The build will automatically fetch the right version for you.

As part of the build we have an initial build step that will do a prerequisite check. Depending on the activated modules, it will check if all preconditions are met and tell you what’s missing.

For details please have a look at the Preparing your Computer page.

Building PLC4X

We have a dedicated page on Building PLC4X.

Please read this page on information about how to build Apache PLC4X.


If you want to work on Apache PLC4X in order to fix things, add things and start contributing in general, please have a look at our Contributing page. It should contain all the information you need.
