Need to access the variable defined in the groovy script file
Before executing the script using GroovyShell
However, I am getting error:
groovy.lang.MissingPropertyException: No such property: _THREADS for class: Test1
//Test1.groovy
_THREADS=10;
println("Hello from the script test ")
//scriptRunner.groovy
File scriptFile = new File("Test1.groovy");
def sharedData = new Binding()
def shell = new GroovyShell(sharedData)
def script = shell.parse (scriptFile);
def thread = script.getProperty('_THREADS'); // getting ERROR --
// No such property: _THREADS for class: Test1
//-------
//now run the threads
script.run()
you have to run script before getting property/binding
def sharedData = new Binding()
def shell = new GroovyShell(sharedData)
def script = shell.parse (''' _THREADS=10 ''')
script.run()
println script.getProperty('_THREADS')
try to open AST Browser (Ctrl+T)
in groovy console for this code:
_THREADS=10
and you'll see approximately following generated class:
public class script1663101205410 extends groovy.lang.Script {
public java.lang.Object run() {
_THREADS = 10
}
}
where _THREADS = 10
assigns property into binding
however it's possible to define _THREADS as a function then it will be accessible without running script.
def sharedData = new Binding()
def shell = new GroovyShell(sharedData)
def script = shell.parse (''' def get_THREADS(){ 11 } ''')
println script.getProperty('_THREADS')
got the solution using @Field
modifier value can be accessed after parsing
import groovy.transform.Field
@Field _THREADS=10
File scriptFile = new File("Test1.groovy");
def sharedData = new Binding()
def shell = new GroovyShell(sharedData)
def script = shell.parse (scriptFile);
def thread = script.getProperty('_THREADS'); //value is accessible
