如何安装eclipse Ditto

Question

我正在尝试在我的Ubuntu18机器上安装Eclipse Ditto，已经安装了Maven和OpenJDK版本"1.8.0_222"，Docker版本18.09.7。运行该命令时：

mvn clean install -Pdocker-build-image \
    -Ddocker.daemon.url=unix:///var/run/docker.sock

我得到以下错误：

这里我漏掉了什么？

提前感谢！

为了“安装”Ditto，你不需要自己构建它(所以你不需要做mvn clean install)。请看一下Running Ditto指南。最简单的方法就是从Docker compose liked文档开始。

您可以找到部署帮助的其他选项(例如Kubernetes、OpenShift、deployment via here )。
