fabric8 docker-maven-plugin错误：jarfile无效或损坏

Question

我正在尝试使用fabric8 docker-maven-plugin在Docker容器中部署并启动spring boot应用程序。

下面是我的docker文件

FROM openjdk:8-jre-alpine
EXPOSE 9095
VOLUME /tmp
ARG JAR_FILE
ADD ${JAR_FILE} app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

这是docker-maven-plugin配置

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

            </plugin>
        </plugins>
    </build>

当我尝试运行mvn clean install时出现以下错误 APP-SERVICEError：jarfile /app.jar无效或损坏

预先感谢
