I want to pass value to my build.gradle file through jenkins (build with params).
I have a String and I need to use this String params to make my release ?
You can use the plugin This build is Parameterized and select string Parameter int that. In this you can define parameter name and value. Suppose PARA is your parameter name and value is its default value, then you can pass this value to build.gradle as $PARA.
