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:
[sts] -----------------------------------------------------

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
