Idea inside add groovy support for project addition

Groovy is a flexible, dynamic language on the Java platform with features like Python, Ruby and Smalltalk, and groovy guarantees that these features are used by Java developers like Java syntax;

Here's a simple example of groovy dynamics, a feature I've come into contact with and like, groovy
1. In Java, the following JUnit test code executes through

    int method (String arg) {
        return 1;
    }

    int method (Object arg) {
        return 2;
    }

    void Dotest () {
        object o = "Object";
        int result = Method (o);
        Assert.assertequals (2, result); Expected return value is 2 ha
    }

2. In groovy, the following JUnit test code executes

    int method (String arg) {
        return 1
    }

    int method (Object arg) {
        return 2
    }

    void Dotest () { C19/>object o = "Object"
        int result = Method (o)
        assert.assertequals (1, result)//Expected return value is 1 ha
    }

Here's the start of configuring groovy for our project in idea. I use a Web project based on SPRING_MVC to import the project;

There are two ways to add the groovy framework support
Method One: Right-click on the item select "Add Framework support ...", tick groovy, and select the groovy dependency package that was introduced on the right-hand side (you can download the source package from the official webpage to local and unzip it, then configure the introduction here);
Method Two: If the project to be added groovy is based on Maven, it is good to add the required dependencies directly in the Pom file;

<dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy-all< /artifactid>
    <version>2.4.4</version>
</dependency>

Then you can add any groovy code to the project, and for more syntax features of Groovy please refer to: Syntax
