sbt仅获取依赖项 [英] sbt only fetch dependencies

问题描述

有没有一种方法只能下载依赖项，而不编译源代码。

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

我之所以问是因为我试图为我的更大项目构建Docker构建环境。
的想法是，在 docker build 期间，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 将频繁更改的代码挂载到Docker容器中并开始编译项目。

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，我只是在构建过程中编译代码，然后在运行时再次对其进行编译。问题在于，当依赖关系发生变化时，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。依赖关系将得到解决和检索。

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