Runtime library for Faktor-IPS. When using the JAXB support use either faktorips-runtime-jakarta-xml or faktorips-runtime-javax-xml as dependency. When using CSV to read tables, add the optional dependencies to opencsv, commons-lang3 and commons-text. If you want to run Faktor-IPS tests as JUnit tests, you need to provide either junit (JUnit 4) or junit-jupiter-api (JUnit 5).

There is a newer version: 25.1.0.a20241030-01
