Maven building a jar with dependencies unpacked inside the JAR

Question

I have a problem with jersey 2.14 and nested jars and I can't figure it out. I looked it up and turns out its a bug with jersey which is still being fixed at the moment.

As a workaround I want to be able to use maven to build a jar with all dependencies unpacked inside my jar. I don't want to have JARs inside lib directory, I want classes. And I can't seem to figure out the maven plugin to do this with.

Can anyone help me out with this?

Thanks,

I figured out my issue. I had to use a built in workout of spring boot self. The really smart people there have figured out that there maybe problematic libraries like Jersey.

You have to use configuration element of spring-boot-maven-plugin.

Put under any jars that will be needed by Jersey (which have dependencies on other jars)

Example

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <mainClass>com.my.Application</mainClass>
                <requiresUnpack>
                    <dependency>
                        <groupId>myapp</groupId>
                        <artifactId>service-commons</artifactId>
                        <version>0.1.3</version>
                    </dependency>
                </requiresUnpack>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
