Hey Thanks for awesome reply..
I have done the same procedure.. I have included groovy jar file n excuted
groovy codes within <groovy></groovy> tags..
Now I am not getting How to pass a variable from <groovy> to the main
script.. i,e How Do i access a variable outside <groovy> tag.. The variable
is set within <groovy> tag..
Here is the sample snippet..
Here list is dynamic and it will keep changing..
that is why i have kept it in <var>
<var id="varID" name="list" value="one,two,three">
<groovy>
//Here i am accessing list as "project.references.varId.list" . It
will give its values
// Here i am doing all operation do reverse and filter
//then i am doing
project.references.varId.list = newList
<groovy>
After this
How can i access the the newlist here (outside <groovy> task)
I tried ${list}
But it is giving old values .. which is set initially..
please do reply.
