Create a Step
Each groovy file within a library’s steps directory will be loaded as a step.
The basename of the groovy file is the name of the step object. For example, a step file build.groovy would be invoked using build() (assuming the step has implemented a call method, more on that later).
The Call Method
Most steps should implement a call method in order to be invoked via stepName() from a pipeline template or other library step.
For example, if a library had a build.groovy file as follows:
void call(){
println "hey from the build step"
}then the build() could be invoked from a pipeline template or other library step.

Multi-Method Steps
While the call method is the default, there is nothing preventing a step from defining multiple methods. These other methods would be invoked with their default notation of stepName.methodName().
For example:
def printMessage(String message){
println "the message is ${message}"
}creates a step test_step that can be invoked via test_step.printMessage("example!").
