I have multiple project gradle build and I am trying to externalize dependencies version via gradle.properties. Unfortunately child project can not find properties in parent gradle.properties

So in parent gradle.properties I have :

SPRING_VERSION=3.2.0.RELEASE

in parent build.gradle I have

dependencies {
    compile "org.springframework:spring-webmvc:$SPRING_VERSION"
    ...

and this works fine. But in the child project same thing cause error :

Could not resolve all dependencies for configuration
Could not find org.springframework:spring-context-support:$SPRING_VERSION.

If I hardcode the version project builds fine.

also in parent file I have settings.gradle which specifies :

include 'projectA','projectB','projectC'

project structure

root
|
\ buildSRC
\ projectA
    |
    \ build.gradle
\ projectB  (build script in parent build.gradle)
\ projectC  (build script in parent build.gradle)
|
|
\ build.gradle
\ gradle.properties
\ settings.gradle

thanks for help

In Groovy, double-quoted Strings support String interpolation, whereas single-quoted Strings don't. Apparently, you mistakenly used a single-quoted String in the subproject. As a result, Gradle went searching for a version that is literally named $SPRING_VERSION, which of course it didn't find.
