Gregory Moltchadski created GROOVY-8792:
-------------------------------------------

             Summary: groovy-json not working from <groovy> Ant task
                 Key: GROOVY-8792
                 URL: https://issues.apache.org/jira/browse/GROOVY-8792
             Project: Groovy
          Issue Type: Bug
          Components: Ant integration, JSON
    Affects Versions: 2.5.0
            Reporter: Gregory Moltchadski
         Attachments: testsuite.7z

groovy-json 2.5.X uses java.util.ServiceLoader to load FastStringService and therefore doesn't work in a multi-classloader environment

build.xml
{code:xml}
<project name="test" default="build" basedir=".">

  <taskdef name="groovy" 
           classname="org.codehaus.groovy.ant.Groovy" 
           classpath="groovy-2.5.2.jar:groovy-ant-2.5.2.jar:groovy-json-2.5.2.jar"/>

  <target name="build">
    <groovy>
    <![CDATA[
      import groovy.json.*
      def json = new JsonSlurper().parseText('{"person":{"name":"Guillaume","age":33,"pets":["dog","cat"]}}')
      println new JsonBuilder(json).toPrettyString()
    ]]>
    </groovy>
  </target>
