maven assembly plugin does not include my classes inside built jar

Question

Any code referenced below is from the project here

For the AWS Lambda, I have been trying to create a jar file based on the maven configuration defined here.

        </configuration>

            <execution>

                </goals>
            </execution>
        </executions>
    </plugin>
 </plugins>

When I try and build the fat JAR, upload it to AWS Lambda console, I see the error

The following package be.quodlibet.hellolambda was not added to the jar resulting in a

"errorMessage": "Class not found: be.quodlibet.hellolambda.helloHandler",
"errorType": "java.lang.ClassNotFoundException"

正如@khmarbaise 在评论中所说，请确保您运行“mvn clean package”而不是“mvn clean assembly:single”。
