Applying Gradle configuration on condition

I would like to apply configuration in Gradle script only when condition met:

useRepo = System.getenv()["IGNORE_REPO_CFG"] == null

buildscript {
    useRepo && repositories {  // <== HERE
        maven.url 'http://localhost:8081/artifactory/release'
    }
}

subprojects {
    configurations {
        all {
            useRepo && resolutionStrategy {  // <== HERE
                cacheChangingModulesFor 0, 'seconds'
                cacheDynamicVersionsFor 0, 'seconds'
            }
        }
    }
}

Because of Groovy/Gradle scope magic I can't pass useRepo to buildscript and subprojects.configurations.all scope.

I read about wrapping in class:

class Cfg {
    static final useRepo = System.getenv()["SA_IGNORE_REPO_CFG"] == null
}

but on Cfg.useRepo I got:

java.lang.ClassNotFoundException: Cfg

UPDATE On:

project.ext.useRepo = System.getenv()["SA_IGNORE_REPO_CFG"] == null
buildscript {
    project.ext.useRepo && repositories {
        maven.url 'http://localhost:8081/artifactory/lognet-release'
    }
}

I got:

Caused by: groovy.lang.MissingPropertyException: Cannot get property 'useRepo' on extra properties extension as it does not exist

Like you tried, you should use project.ext:

project.ext.useRepo = System.getenv()["SA_IGNORE_REPO_CFG"] == null

but when you now try to use project.ext inside subprojects it is empty, because it is not defined in this project. so you need to access it with ``rootProject.ext`, cause you defined it there

subprojects {
    configurations {
        all {
            rootProject.ext.useRepo && resolutionStrategy {  // <== HERE
                cacheChangingModulesFor 0, 'seconds'
                cacheDynamicVersionsFor 0, 'seconds'
            }
        }
    }
}

Your try the use the ext inside the buildscript, but that doesn't work, because the buildscript-closure gets executed first, and then the other script. See this Gradle Discussion

If you want to do this all, you can specify this variable on the gradle.ext inside the settings.gradle. 

gradle.ext.useRepo = System.getenv()["SA_IGNORE_REPO_CFG"] == null

and then use it.

buildscript {
    gradle.ext.useRepo && repositories {
        maven.url 'http://localhost:8081/artifactory/lognet-release'
    }
}
