[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.22.1:build (default-cli) on project auth-server: Unable to parse configuration of mojo io.fabric8:docker-maven-plugin:0.22.1:build for parameter buildArgs: Cannot find 'buildArgs' in class io.fabric8.maven.docker.config.BuildImageConfiguration -> [Help 1]

下面是我的构建配置

        <plugin>

更新 2：

【问题讨论】：

您是否尝试过改用<args>？见dmp.fabric8.io/#build-configuration
感谢您的评论。我确实尝试过。还是不行

下面为我工作

pom.xml

<images>
    <image>
        <name>${docker.image.prefix}/${docker.image.name}</name>
        <build>
            <dockerFileDir>${project.basedir}/src/main/docker/</dockerFileDir>
            <!--copies artifact to docker build dir in target-->
            <assembly>
                <descriptorRef>artifact</descriptorRef>
            </assembly>
            <args>
                <IMAGE_VERSION>${build.version}</IMAGE_VERSION>
            </args>
            <tags>
                <tag>latest</tag>
                <tag>${project.version}</tag>
            </tags>
        </build>
    </image>
</images>

Dockerfile

FROM ...
ARG IMAGE_VERSION
VOLUME /tmp
ADD maven/spring-boot-docker-${IMAGE_VERSION}.jar myapp.jar
....

以下工作。

<images>
    <image>

        <name>${docker.image.prefix}/${project.artifactId}</name>
        <build>
            <dockerFile>Dockerfile</dockerFile>
            <assembly>
                <descriptorRef>artifact</descriptorRef>
            </assembly>
            <args>
                <FINAL_NAME>${project.build.finalName}.${project.packaging}</FINAL_NAME>
            </args>
        </build>
    </image>
</images>
