[gradle-user] Multi-project Ant build and XmlTask

[gavares]

I've been wrestling with this for about a day now. I'm attempting to invoke a
build.xml file from a gradle script and the build.xml in question has a
taskdef for com.oopsconsultancy's XmlTask. The build.xml runs fine when
invoked via ant. Invoking from build.gradle fails because it cannot find the
class for XmlTask. My build.gradle:


configurations {                                                                
          
  antcp {                                                                       
          
    description = 'ant classpath'                                               
          
    transitive = true                                                           
          
    exclude module: 'ant'                                                       
          
  }
}   
    
dependencies {
  antcp "ant-contrib:ant-contrib:1.0b3"                                         
          
  antcp "com.oopsconsultancy:xmltask:1.16"                                      
          
}                                                                               
          
  
  
task gradleDist << {
  println "PATH: ${configurations.antcp.asPath}"                                
          
  ant.taskdef resource: "net/sf/antcontrib/antcontrib.properties",              
          
                classpath: configurations.antcp.asPath                          
          
  ant.taskdef(name: 'xmltask', classname:
'com.oopsconsultancy.xmltask.ant.XmlTask', classpath:
configurations.antcp.asPath)
  ant.ant antfile: "build.xml", target: "dist", dir: "."                        
          
  ant.ant antfile: "build.xml", target: "build-dist-artifact", dir: "."         
          
}



When building, the ant path is printed as:


/home/builder/.gradle/caches/artifacts-4/ant-contrib/ant-contrib/76dd5c26956e9373dcceb581ac0cfb1c/jars/ant-contrib-1.0b3.jar:/home/builder/.gradle/caches/artifacts-4/com.oopsconsultancy/xmltask/76dd5c26956e9373dcceb581ac0cfb1c/jars/xmltask-1.16.jar


So I can see that xmltask is on my ant classpath but the build script fails
with the following error:


    taskdef class com.oopsconsultancy.xmltask.ant.XmlTask cannot be found
     using the classloader AntClassLoader[]


The build.xml has a taskdef for XmlTask like:


&lt;taskdef name="xmltask"
classname="com.oopsconsultancy.xmltask.ant.XmlTask"/&gt;



Not sure what I'm doing wrong.
