父 POM：

                </executions>
                <configuration>
                    <repository>${docker.image.prefix}/${project.artifactId}</repository>
                    <tag>${project.version}</tag>
                    <buildArgs>
                        <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
                    </buildArgs>
                    <contextDirectory>${basedir}/</contextDirectory>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

子模块 POM：

<build>
    <plugins>
        <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>dockerfile-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

使用命令为模块 1 构建 docker 镜像：

mvn -pl module-1,module-2,module-3 -am clean install

输出：

使用 Dockerfile 中的 module-1，因为它有 4 个步骤（而 module-4 有 2 个步骤）。

检查泊坞窗图像：

$ docker image list

输出：

REPOSITORY                     TAG              IMAGE ID       CREATED          SIZE
***/module-1               1.0-SNAPSHOT     ad16766ec096   16 minutes ago   456MB
...

所以，我们可以为父 pom 做的是：

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>dockerfile-maven-plugin</artifactId>
    <version>1.3.6</version>
    <configuration>
        <skip>true</skip>
    </configuration>
</plugin>

在子 pom 中：

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>dockerfile-maven-plugin</artifactId>
    <configuration>
        <skip>false</skip>
        <repository>${docker.image.prefix}/${project.artifactId}</repository>
        <tag>${project.version}</tag>
        <useMavenSettingsForAuth>true</useMavenSettingsForAuth>
        <buildArgs>
            <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
        </buildArgs>
        <contextDirectory>${project.basedir}/</contextDirectory>
    </configuration>
 </plugin>

覆盖跳转到 false

所以现在如果我们运行 mvn dockerfile:build ，它会运行 docker 插件并为每个子模块读取 Dockerfile 。但是，如果您想将此应用于特定模块，您可以运行 mvn -pl your-module dockerfile:build 以便我们不需要的其他模块不会在反应器摘要中运行。

另外，你可以在你想要的孩子中添加执行
