How do I copy third-party jars to my target jar using Maven 3.6.0

Question

I am trying to create a executable jar with Maven where all the third-party dependency jars are in the root. Included are two pics for examples, and my pom.xml

With this pom, I am getting this result just below it where the jars are broken out into folders.

Here is what I need with the full jars included.

I see other threads on this subject, and I believe my pom is correct. But, I can't seem to get there.

Thanks.

I am not sure why you are using all the 3 maven plugins - jar, shade and assembly.

Could you try using either shade or assembly plugin. You could also refer (if not already) following link to check these plugin usages:

Difference between maven plugins ( assembly-plugins , jar-plugins , shaded-plugins)

thank you. I removed all by shade. Same result. After looking at the pictures of the two jars, do you know how to get the dependent JARS inside the uber-jar? – Davidson May 13 '19 at 14:43
Please use maven-shade-plugin and refer following link which provides example around how to use maven shade plugin - https://maven.apache.org/plugins/maven-shade-plugin/examples/includes-excludes.html – Anshul Singhal May 13 '19 at 14:59
I was using all three from ignorance. – Davidson May 13 '19 at 15:34
Please use only maven-shade-plugin (remove maven-jar-plugin and maven-assembly-plugin) and refer already shared link. – Anshul Singhal May 13 '19 at 15:50
I resolved it but by not using Maven. I could never get Maven to include the actual jars. So, I used Eclipse Export to Runnable Jar instead. – Davidson May 13 '19 at 16:12

Please remove maven-assembly-plugin and maven-jar-plugin completely from pom.xml file and then just use maven-shade-plugin as follows:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.2.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Then run mvn clean package and check generated JAR file.
