在当前项目和插件组中找不到前缀 'docker' 的插件

Question

使用 docker 部署 Spring Cloud 项目，pom.xml 中的一些代码：

<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>${project.basedir}/src/main/docker</dockerDirectory>
                <resources>
                    <resource>
                        <targetPath>/</targetPath>
                        <directory>${project.build.directory}</directory>
                        <include>${project.build.finalName}.jar</include>
                    </resource>
                </resources>
            </configuration>
        </plugin>
        <!-- end::plugin[] -->
    </plugins>
</build>

当我执行命令时：mvn package docker:build，它抛出上述错误：

如何解决？

Answer 1

将以下代码添加到您的maven conf/setting.xml：

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

Answer 2

我的工作方式不同，如果您遵循 Maven 插件模式 {prefix}-maven-plugin... 在本例中为 dockerfile-maven-plugin，您应该能够运行与：mvn package dockerfile:build。我正在使用 Maven：3、Spring Boot 2 和 Docker maven 插件 1.3.4

Answer 3

如果你使用的是dockerfile maven插件，你需要将docker:build改为 dockerfile:build 和 docker:push 到 dockerfile:push

在当前项目和插件组中找不到前缀 'docker' 的插件

No plugin found for prefix 'docker' in the current project and in the plugin groups

maven-3

docker

spring-boot

spring-cloud
