# 原因

springboot 项目 pom 里引入了 docker-maven-plugin,使用 mvn clean package docker:build 时遇到该问题

<plugin>
	<groupId>com.spotify</groupId>
	<artifactId>docker-maven-plugin</artifactId>
	<version>1.2.0</version>
	<configuration>
		<imageName>${project.artifactId}:${project.version}</imageName>
		<dockerDirectory>${project.basedir}</dockerDirectory>
		<resources>
			<resource>
				<targetPath>/</targetPath>
				<directory>${project.build.directory}</directory>
				<include>${project.build.finalName}.jar</include>
			</resource>
		</resources>
	</configuration>
</plugin>

# 修改方法

修改 maven 下的配置文件 settings.xml,重新 build 一下

<settings>
    <pluginGroups>
        <pluginGroup>com.spotify</pluginGroup>
    </pluginGroups>
</settings>
