Documentation should clarify distinction between global variable access vs. plain class references

XMLWordPrintable

      Documentation says "Internally, scripts in the vars directory are instantiated as a singleton on-demand, when used first."

      Here is a very basic example to demonstrate it's not the case:

      // vars/acme.groovy

def setFoo(v) {
    this.foo = v;
}
def getFoo() {
    return this.foo;
}

      // src/com/foo/Zot.groovy

package com.foo

def printAcmeFoo() {
    try {
        echo acme.foo
    } catch (e){
        echo "acme.foo is undefined"
    }
}

      And here is a pipeline:

      import com.foo.Zot

node{
    acme.foo = "5"
    echo acme.foo;
    
    Zot z = new Zot()    
    z.printAcmeFoo()
}

      Actually it shows 2 issues:
      1/ scripts in the vars directory are not singletons
      2/ when accessing undefined field pipeline will hang indefinitely
