在配置文件中分配值

Question

I am having an application.conf file in resources of an SBT project.

How can I assign variables inside this file?

For example:

project {
  fun1-version: "0.1.0-SNAPSHOT"
  fun2-version: "0.0.1-SNAPSHOT"
  fun3-version: "0.0.1-SNAPSHOT"
  fun4-version: "0.0.1-SNAPSHOT"

}

So I do not want every time to change this 0.0.1 for each line. I have tried the following:

versions {
  ver1 : "0.0.1"
}

project {
  fun1-version: ${versions.ver1}"-SNAPSHOT"
  fun2-version: ${versions.ver1}"-SNAPSHOT"
  fun3-version: ${versions.ver1}"-SNAPSHOT"
  fun4-version: ${versions.ver1}"-SNAPSHOT"
}

But it does not seem that it is working. Any idea how can I do it?

Your config file is correct. You need to call resolve() on your config object after loading it.
