Gradle properties using in config file

i set in gradle.properties a value :
myJarVer.version=3.4.0
in the config file of on of the subprojects i want to do :
dependencies {
compile “org.slf4j:slf4j-api:${myJarVer.version}

}

how can it be set?

The property myJarVer.version is set to 3.4.0, but you cannot access it directly due to the dot in the property name. As written, the code looks for a nested version property on myJarVer. If you want to have a dot in the property name, you need to make sure that myJarVer.version as a whole is treated as the property name using syntax such as:

dependencies {
   compile "org.slf4j:slf4j-api:${property('myJarVer.version')}"
}

Thanks!
this solved the issue
