Why groovy doesn't print a globally defined variable?

Question

Here defined a doesn't print inside an method doit().

Integer a =0

void doit ()
{
    println a
}

May be i am stupid to ask it. Whats happening here ?

Answer 1

You need to make scope available for given method as follows,

import groovy.transform.Field
@Field Integer a = 1
void doit () { 
println a
}

doit ()​​​​​​​​​​​​
