Mandatory requirements:

• Java 21 (JDK flavour (OpenJDK/Azul/Oracle) does not matter). For the correct Java version setup I can recommend JEnv (Mac/Linux) and the Maven Toolchains Plugin (Windows)

$ java -version openjdk version "21.0.2" 2024-01-16 LTS OpenJDK Runtime Environment Temurin-21.0.2+13 (build 21.0.2+13-LTS) OpenJDK 64-Bit Server VM Temurin-21.0.2+13 (build 21.0.2+13-LTS, mixed mode) 

• Docker Engine (Community Edition is enough):

$ docker version Client: Docker Engine - Community Version: 20.10.6 API version: 1.41 Go version: go1.13.15 Git commit: 370c289 Built: Fri Apr 9 22:47:17 2021 OS/Arch: linux/amd64 Context: default Experimental: true Server: Docker Engine - Community Engine: Version: 20.10.6 API version: 1.41 (minimum version 1.12) Go version: go1.13.15 Git commit: 8728dd2 Built: Fri Apr 9 22:45:28 2021 OS/Arch: linux/amd64 Experimental: false 

Optional requirements:

• Maven >= 3.6 (the project also includes the Maven Wrapper).

When using Maven from the command line, make sure ./mvnw -version reports the correct Java version:

$ ./mvnw -version Apache Maven 3.8.4 (9b656c72d54e5bacbed989b64718c159fe39b537) Maven home: /home/rieckpil/.m2/wrapper/dists/apache-maven-3.8.4-bin/52ccbt68d252mdldqsfsn03jlf/apache-maven-3.8.4 Java version: 17.0.1, vendor: Eclipse Adoptium, runtime: /usr/lib/jvm/jdk-17.0.1+12 Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "5.4.0-92-generic", arch: "amd64", family: "unix" 

• IntelliJ IDEA or any IDE/Code Editor (Eclipse, NetBeans, Code, Atom, etc.)
