I have a RESTful API project where I use Spring Boot Maven. I'm also processing in Matlab with a jar file. I converted this project to .jar file, but running it with java -jar demo.jar closes after running. I got some errors. However, since it was a restful API, it had to remain open so that I could access the APIs.

How to fix these problems?
Finally I solved the problem. As you can see in the pom.xml file, i added some <scope></scope>. And also as you can see in the errors it couldn't find javabuilder. After adding this in plugin:
<configuration>
<includeSystemScope>true</includeSystemScope>
</configuration>
the problem was solved successfully.
