Execution of xjc taskdef of ant buildfile causing problems


(freddy.c4) #1

Hi,

I want to execute an ant target directly from gradle. But executing this target fails. I reproduced the error with the following code, which is a part of our code generation: build.xml

<?xml version="1.0" encoding="UTF-8"?>
<project name="generateSrc" default="generate">
 <target name="generate" unless="gen.uptodate">
  <path id="xjc.libs">
   <fileset dir="lib/cxf">
    <include name="*jaxb*.jar" />
   </fileset>
  </path>
  <taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask" classpathref="xjc.libs" />
      <echo message="Creating Java files from XSDs in src/main/resources" />
  <mkdir dir="src-gen" />
  <xjc destdir="src-gen" binding="src/main/resources/binding.xjb" extension="true" encoding="UTF-8">
   <schema dir="src/main/resources">
    <include name="*.xsd" />
   </schema>
  </xjc>
      <echo message="before touch"/>
  <touch file="src-gen/.last-generator-run" />
  <echo message="after touch"/>
 </target>
</project>

build.gradle

ant.importBuild 'build.xml'

I execute the ‘generate’ target in eclipse (exactly the same error occurs when executing the target on command line) and get the following output:

I figured out that the ant task ‘xjc’ is causing this problem, that some ant tasks can’t executed anymore, but i don’t know why … When I execute the ant target with ant, there’s no problem at all. Does anyone know, what could make gradle to respone in this way?

Note: We are using Gradle 1.7

Interesting. The only thing that fails from that ant script is the “touch” task…

What is even more strange is that printing out the URLs from the embedded ant class shows the ant-launcher-1.8.4.jar file being included.

generate {
  doFirst {
    ClassLoader antClassLoader = org.apache.tools.ant.Project.class.classLoader
    println antClassLoader.URLs.each { println it }
}
