@Grab is not working in my Eclipse Groovy project

1888

Following is my groovy script I am writing in my existing Java project

@Grab("org.codehaus.groovy:groovy-json")

import groovy.json.JsonSlurper
import java.util.stream.Collectors


def jsonString = '''
{
  "results": [
    {
      "foo": "bar1",
      "name": "0.45.003"
    },
    {
      "foo": "bar1",
      "name": "0.45.002"
    },
    {
      "foo": "bar1",
      "name": "0.45.001"
    }
  ]
}
'''

def jsonSlurper = new JsonSlurper()
def json = jsonSlurper.parseText(jsonString);

//json = json.results.collect( it.name )

println json

When I run this, It's failing with the folowing error

Figured out myself, We need to add ivy dependencies to make this work.

1. If maven project add the following to dependencies

<!-- https://mvnrepository.com/artifact/org.apache.ivy/ivy -->
<dependency>
    <groupId>org.apache.ivy</groupId>
    <artifactId>ivy</artifactId>
    <version>2.1.0</version>
</dependency>

2. If you are using gradle add the following to your build.gradle

compile group: 'org.apache.ivy', name: 'ivy', version: '2.1.0'
