[错误] 无法在项目 Bookstore 上执行目标 com.spotify:docker-maven-plugin:1.0.0:build (default)：捕获异常：java.util.concurrent.ExecutionException：com.spotify.docker.client.shaded。 javax.ws.rs.ProcessingException: org.apache.http.conn.HttpHostConnectException: 连接到 localhost:2375 [localhost/127.0.0.1] 失败: 连接被拒绝

为什么这个异常不断发生，我该如何解决它，我正在从 war 文件构建 docker 图像。
