           <groupId>org.apache.maven.plugins</groupId>
               <artifactId>maven-enforcer-plugin</artifactId>
                <version>3.0.0-M1</version>
                <executions>
                    <execution>
                        <id>enforce-maven</id>
                        <goals>
                            <goal>enforce</goal>

                                </requireMavenVersion>
                        </rules>

                </configuration>
            </plugin>
        </plugins>
    </build>

3. Compile
3.1 Run "mvn -e clean test-compile compile" (-e for error stack trace)
3.* possibly required updates: "mvn versions:display-dependency-updates" and "mvn versions:display-plugin-updates"

4. Create local runtime
4.1 Run "jdeps --list-deps VadereGui/target/vadere.jar"
4.2 Run "jlink --no-header-files --no-man-pages --compress=2 --strip-debug --add-modules java.base,java.compiler,java.datatransfer,java.desktop,java.logging,java.management,java.naming,java.prefs,java.rmi,java.scripting,java.sql,java.xml --output java-runtime"
// The main output of jdeps is used as the parameter for jlink --add-modules.
4.3 Run "java-runtime/bin/java -jar VadereGui/target/vadere.jar"
