I think i have the same problem mentioned here
maven compilation failure
Found the problem but not the cause
I removed the following dependency and everything is okay
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
after removing the plugin the jar is build in a different structure. When spring boot plugin was there the whole content was inside BOOT-INF folder which i think was the cause, not sure though... need expert opinion here.

Answer 1

The easiest way to solve this is through a so called reactor project, where you build all dependent modules with the parent pom. To that end, add the following code to your parent POM:
<modules>
<module>common</module>
<module>search</module>
</modules>
Now, build the parent pPOM and your entire build should work.
Also, don't use explicit versions in the child projects, only inherit the version from the parent POM (I think you're good there). If you reference dependencies from the same project reactor, use the version ${project.version}.

Found the solution. May be somebody will find it useful.
