还要注意项目文件 [英] Watch for project files also
问题描述
我以下列方式使用 sbt:我在 sbt 中运行 ~ test:compile 然后在 IDE 中工作，偶尔观察项目是否仍然编译，因为 IDE 的演示文稿编译器往往有问题.当我 git pull 一些代码时，project/ 文件中可能会有变化，所以我想重新加载.有没有办法，如何同时查看源文件和项目文件，这样当项目文件发生变化时，我才真正得到更新?
I use sbt in the following fashion: I run ~ test:compile in sbt and then work in IDE, watching occasionaly if the project still compiles, because the IDE's presentation compiler tends to be buggy. When I git pull some code, there might be changes in the project/ files, so I want to have reload. Is there a way, how to watch both source files and project files, so when there is change in project files, I actually get the update?
推荐答案
你实际上不能使用 ~ 并让它立即重建项目本身，因为 ~ 需要读取构建定义本身来确定:
You actually can't use ~ <task> and have it rebuild the project itself right now, because ~ <task> needs to read the build definition itself to determine:
- 观看哪些源文件
- 如何运行任务.
您正在做的是在项目/更改时更改配置.这需要 sbt 的完整reload 或 reboot 以拉入新配置.
What you're doing is altering the config whe project/ changes. This requires a full reload or reboot of sbt to pull in the new configuration.
所以，从 sbt 0.13 开始，这是不可能的.您可以拥有它，以便在 project/ 更改时重建您的源代码，但无需重建构建定义，没有太大帮助.
So, as of sbt 0.13, this isn't possible. You can have it so it will rebuild your source code when project/ changes, but without rebuilding the build definition, not much help.
您可以创建一个新的 sbt 提示或任务，运行时可以检查项目/中的源文件是否已更新并发出警告/错误，以便您知道重新启动.这可能是目前最好的选择.
You could create a new sbt prompt, or task, that when run could check to see if source files in project/ are updated and issue a warning/error so you know to reboot. That's probably the best option right now.
