Grails import class from java or groovy folder

I put several .groovy scripts in the src/groovy/search/ folder and got astrayed on how to use them in my controller. My controller is grails-app/controller/EnvironmentController.groovy and I want to know how to import the classes like

import src.groovy.search.*

Also it's appreciated if anybody could point me to a complete explanation how the import works in Grails (namely how the groovy and java folders are included in the project and how to import them, including importing the java folder inside the groovy one). Thanks!

Edit: My grails is on 2.4.4

Use and IDE: (Grails 2 or less GGTS/STS) (Grails 3 Intelij community edition)

Organise import feature short cuts:

on GGTS/STS(Eclipse)

Ctrl + shift + o all together

on Intelij

Ctrl + Alt + o all together

In your case, if you are using vi or some text editor then all you need is :

import search.*

i.e. remove src.groovy.

Imports in Grails works in same fashion as in Java. You put your groovy files under src/groovy and java files under src/java. While importing simply import with the package name and no need to include src or groovy in import.

For how to execute groovy scripts in controller or anywhere, you can't just import them. I am assuming you are talking about groovy script and not groovy class. To execute a groovy script, you have two choices.

Suppose you Sample.groovy script file contains below code

public void sayHello(String name) {
    println "Say Hello to $name..."
}

public static void sayStaticHello(String name) {
    println "Say Static Hello to $name..."
}

So in order to execute it in your controller you can do either:

def script = new GroovyShell().parse(new File('<Path to SampleScript.groovy>'))
script.sayHello("Sandeep Poonia")
script.sayStaticHello("Sandeep Poonia")

or

//for non-static methods
this.class.classLoader.loadClass("SampleScript").newInstance().invokeMethod("sayHello", "Sandeep Poonia")

//for static method
this.class.classLoader.loadClass("SampleScript").invokeMethod("sayStaticHello", "Sandeep Poonia")
