> Groovy doesn't support concatenation using + or << *at line start*,
> Use case: Need to concatenate a many variables and want to make it readable, but failed to separate lines similar to  java
> 1. Java supported code:
> String text= "0"+"1" +
> "2" 
> +"3";
>  
> Error:
> javax.script.ScriptException: groovy.lang.MissingMethodException: No signature of method: java.lang.String.positive() is applicable for argument types: () values: []
> Possible solutions: notify(), tokenize(), size(), size()
>  
> 2. groovy concatenation split in new line(s):
> {{String text ="<id>" <<vars["id1"] << "<id><id2>" }}
> {{<< vars["id2"] << "<id2>";}}
> {{Error:}}
> Caused by: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> Script1.groovy: 2: unexpected token: << @ line 2, column 1.
>    << vars["id2"] << "<id2>"
