docker maven 出錯：Failed to execute goal com.spotify:docker-maven-plugin:...: Request error: POST http

Spring Boot項目構建docker鏡像，出錯Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default-cli) on project SpringBoot2: Exception caught: Request error: POST https://192.168.99.100:2376/build?t=mytest/SpringBoot2: 500: HTTP 500 Internal Server Error

出現這個錯的緣由確實出人意料——竟然是由於大小寫問題...

我是在pom.xml里加入了docker構建用的插件：

　　　　　　<plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>0.4.13</version>
                <configuration>
<!--                     <imageName>${docker.image.prefix}/${project.artifactId}</imageName> 這裏取得是項目名字，個人項目名字是SpringBoot2，致使失敗-->
                    <imageName>mytest/springboottest</imageName>
<!--                     <dockerDirectory>src/main/docker</dockerDirectory> -->
                    <dockerDirectory>./</dockerDirectory>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
