maven - 无法解析 mojo org.apache.maven.plugins:maven-shade-plugin:3.0.0:shade 参数转换器的配置

问题描述

我正在尝试使用 java8 运行时为我的 aws lambda 函数配置 log4j2。Aws lambda 处理程序确实提供了 context-Lambdalogger，但我想使用标准的 log4j 配置，以便可以在每个类中声明它并根据需要记录它，而无需将 context-Lambdalogger 传递给每个方法等等。根据 aws 文档，我尝试使用以下依赖项和插件，如下所述。但我收到以下错误。任何线索或想法都可以提供帮助。

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.0.0:shade (default) on project lcc: Unable to parse configuration of mojo org.apache.maven.plugins:maven-shade-plugin:3.0.0:shade for parameter transformer: Cannot create instance of interface org.apache.maven.plugins.shade.resource.ResourceTransformer: org.apache.maven.plugins.shade.resource.ResourceTransformer.<init>() -> [Help 1]

          <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>3.2.4</version>
                <configuration>
                    <createDependencyReducedPom>false</createDependencyReducedPom>
                </configuration>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
