Jar export in IntelliJ IDEA vs Eclipse built-in method

I used IntelliJ IDEA to generate jar file with maven-assembly-plugin.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>3.1.0</version>
    <executions>
        <execution>
            <id>make-assembly</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <archive>
            <manifest>
                <mainClass>test.LeanFTest</mainClass>
            </manifest>
        </archive>
        <finalName>${project.artifactId}-fatjar-${project.version}</finalName>
        <appendAssemblyId>false</appendAssemblyId>
    </configuration>
</plugin>

It was not worked, was unable to use jar file, so I imported project to Eclipse and used built-in jar export option. This jar is working fine. I couldn't find, what is difference between these jar files.
