如何要求 sbt 只获取依赖项而不编译? [英] How to ask sbt to only fetch dependencies, without compiling?

问题描述

有没有办法只下载依赖而不编译源码.

Is there a way to only download the dependencies but do not compile source.

我之所以这么问，是因为我正在尝试为我的更大项目构建一个 Docker 构建环境.想法是在 docker build 我克隆项目，下载所有依赖项，然后删除代码.然后使用docker run -v将经常变化的代码挂载到docker容器中，开始编译项目.

I am asking because I am trying to build a Docker build environment for my bigger project. The Idear is that during docker build I clone the project, download all dependencies and then delete the code. Then use docker run -v to mount the frequently changing code into the docker container and start compiling the project.

目前我只是在构建期间编译代码，然后在运行时再次编译.问题在于，当依赖项发生变化时，我必须从头开始构建，这需要很长时间.

Currently I just compile the code during build and then compile it again on run. The problem ist that when a dependencie changes I have to build from scratch and that takes a long time.

推荐答案

运行 sbt 的 update 命令.将解析和检索依赖项.

Run sbt's update command. Dependencies will be resolved and retrieved.
