Groovy Libraries allow custom Groovy functions and helpers to be shared and reused across all Groovy scripts in FlexDeploy

...

Lets look at what happens when FlexDeploy compiles and creates instances of your custom libraries that will be added to for other Groovy scripts to use.

1. FlexDeploy will iterate through all your Groovy Libraries and create instances an instance of each.

2. A new instance of LIB_ONE is created.

3. During initialization of LIB_ONE it will create a new instance of LIB_TWO as declared on line 1 of LIB_ONE

4. An instance of LIB_TWO is created during step 3. This in turn creates an instance of LIB_ONE as declared on line 1 of LIB_TWO.

   1. We are now stuck in a loop between steps 3 and 4, infinitely creating new instances. This is what is known as a circular dependency and will result in an error being thrown.

def libTwo = new com.flexagon.groovy.custom.LIB_TWO(LOG)

def myFunction() {
  // do some logic
}

import com.flexagon.groovy.custom.LIB_ONE;

def myFunction() {
  def libOne = new LIB_ONE(LOG)
  // do some logic
}
