未能执行目标com.spotify：docker-maven-plugin：1.0.0：build捕获的exception：basedir src / main / docker不存在

使用docker部署Spring Cloud项目，在pom.xml部分代码：

 <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <!-- tag::plugin[] --> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.0.0</version> <configuration> <imageName>${docker.image.prefix}/${project.artifactId}</imageName> <dockerDirectory>src/main/docker</dockerDirectory> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> <!-- end::plugin[] --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <skipTests>true</skipTests> </configuration> </plugin> </plugins> </build> 

当我运行命令： mvn package docker:build ，它会引发错误：

我的项目有src/main/docker这个文件，怎么解决呢？
