如何要求sbt仅获取依赖项,而不进行编译? [英] How to ask sbt to only fetch dependencies, without compiling?
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正在尝试为我的更大项目构建Docker构建环境.想法是,在 docker build
期间,我克隆了项目,下载了所有依赖项,然后删除了代码.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.
