Answer 1

Thanks for posting the question. I have spent some time researching exactly the same issue. I use gradle to build jar and I needed to include:

bootJar {
    launchScript()
}

Then just make sure that you run newly created file.

You are most likely missing the <executable> option in your build configuration. Without it you are producing a regular JAR, not executable one.

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