Procrun Error: FindClass org/springframework/boot/loader/JarLauncher failed

Question

I am trying to create a service from my Springboot jar with Apache Commons Daemon procrun. When I try to run the service I get the "FindClass org/springframework/boot/loader/JarLauncher failed"-Error.

In my POM I added:

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <executable>true</executable>
                </configuration>
            </plugin>

and

<packaging>jar</packaging>

The full Error-Log:

Please help me solve this error. I also take suggestions for other tools that are easy to handle. Notice I cannot use NSSM.
