Groovy script is not executing in the Camel (Project) - intellij-idea

Question

Scenario: Just wanted to transfer the files from one location to another
location using camel and groovy script
Problem: I am not seeing any errors in the console, but how can we make
sure script is executing.
Sample MainApp Program :
class MainApp {
static void main(String... args) {
def camelContext = new DefaultCamelContext()
println("printing something in the console MainApp")
camelContext.addRoutes( new RouteBuilder() {
#Override
void configure() {
println("Printing some thing before queue")
from("Test").to("Test")
println("printing something after queue")
}
})
//camelContext.start()
// Thread.sleep(10000)
// camelContext.stop()
}
}
Output :
sampling ...
include patterns:
org\.apache\.camel\..*
exclude patterns:
printing something in the console MainApp
Printing some thing before queue
printing something after queue
Process finished with exit code 0
Pom.xml file: If you could observe, below file contains all the jar files which are related to groovy and camel.. (I am thinking there are problems with pom file.. please let me know if you are finding out the same)

Above same app I executed in java: I am getting an error(As expected)
Caused by: org.apache.camel.FailedToCreateRouteException: Failed to
create route route1: Route(route1)[[From[Test]] -> [To[Test]]] because
of No endpoint could be found for: Test, please check your classpath
contains the needed Camel component jar.
The same thing I am expecting from groovy script .. please suggest me if
I am missing anything.

Answer 1

I am giving myself an answer to the above question. I haven't thought of executing a simple way of writing Groovy script. I have tried below code and it is working.
package org.apache.camel
import org.apache.camel.impl.*
import org.apache.camel.builder.*
def camelContext = new DefaultCamelContext()
camelContext.addRoutes(new RouteBuilder() {
def void configure() {
from("Test")
.to("Test")
}
})
camelContext.start()
addShutdownHook{ camelContext.stop() }
synchronized(this){ this.wait() }
Maybe we can make execute above-posted question with the groovy script .. but I am not seeing any console logs when an error occurs. Please suggest me on this .. I really would like to know how the process executes .. thanks a lot advance.
