如何为容器使用不同的Web应用程序资源:SBT中的启动和打包任务 [英] How to have different webapp resources for container:start and package tasks in SBT

问题描述

我有一个带有纯JS前端和Scala后端的Web应用程序.我想在构建管道中使用Grunt来处理 src/main/webapp 到目标 dist/webapp 目录中，该目录具有串联/缩小的js和html文件，已编译的sass表等我还想保留原始的JS和HTML文件，以便使用container:start任务进行本地测试，而package任务将使用Grunt处理的资源来构建我的WAR文件. 当我在SBT中使用以下设置时:

I have a web application with pure JS frontend and Scala backend. I would like to use Grunt in my build pipeline to process src/main/webapp into target dist/webapp dir with concatenated/minified js and html files, compiled sass sheets etc. I also want to preserve original JS and HTML files for local testing using container:start task, while the package task would build my WAR file with resources processed by Grunt. When I use following setting in SBT:

webappResources in编译<< = baseDirectory {bd => Seq(bd/"dist"/"webapp")}

webappResources in Compile <<= baseDirectory { bd => Seq(bd / "dist" / "webapp") }

然后我实现了第二个目标-我的WAR是使用 dist/webapp 中的webapp资源构建的.但是，在本地开发过程中使用container:start时，我会绑定到同一目录. 有什么方法可以为不同的目的定义不同的目录吗?

then I achieve the second goal - my WAR gets built using the webapp resources in dist/webapp. However, when using container:start during local development I get bound to the same directory. Is there any way to define different dirs for different purposes?

推荐答案

xsbt-web-plugin支持SBT 0.13.1 ，因此您可以使用更精细的语法在Compile范围内定义webappResources:

xsbt-web-plugin supports SBT 0.13.1 so you can use the much-nicer syntax to define webappResources in the Compile scope:

webappResources in Compile := Seq(baseDirectory.value / "dist" / "webapp")

我可能会记错了，但是单独使用webappResources也可以.

I might be mistaken, but webappResources alone would work, too.

webappResources := Seq(baseDirectory.value / "dist" / "webapp")

甚至(除非您想替换原始值而不附加值):

or even (unless you want to replace the original value not to append a value):

webappResources += baseDirectory.value / "dist" / "webapp"

对于该解决方案，我将在build.sbt中使用以下内容(未经测试的):

As for the solution I'd use the following (untested) in build.sbt:

webappResources in package := Seq(baseDirectory.value / "dist" / "webapp")

，并保留webappResources设置的默认值以进行本地开发.

and leave the default value for the webappResources setting for local development.

阅读范围，以了解有关范围界定"的更多信息"设置，即为不同的 axes 设置不同的值.
