java - maven 程序集插件不包括我在构建的 jar 中的类

Question

下面引用的任何代码都来自项目 here

对于 AWS Lambda，我一直在尝试根据此处定义的 maven 配置创建一个 jar 文件。

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

当我尝试构建胖 JAR 并将其上传到 AWS Lambda 控制台时，我看到了错误

以下包 be.quodlibet.hellolambda 没有添加到 jar 中，导致

"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”。
