Building from Sources

To ensure reproducible builds this Maven project inherits from the vegardit-maven-parent project which declares fixed versions and sensible default settings for all official Maven plug-ins.

The project also uses the maven-toolchains-plugin which decouples the JDK that is used to execute Maven and it's plug-ins from the target JDK that is used for compilation and/or unit testing. This ensures full binary compatibility of the compiled artifacts with the runtime library of the required target JDK.

To build the project follow these steps:

  1. Download and install a Java 17 SDK, e.g. from:

  2. Download and install the latest Maven distribution.

  3. In your user home directory create the file .m2/toolchains.xml with the following content:

    <?xml version="1.0" encoding="UTF8"?>

    Set the [PATH_TO_YOUR_JDK_17] parameter accordingly.

  4. Checkout the code using one of the following methods:

  5. Run mvn clean verify in the project root directory. This will execute compilation, unit-testing, integration-testing and packaging of all artifacts.
