Ant target fails then imported into gradle


(Klaus Christiansen) #1

I have a problem with an Ant target imported into a gradle build file.

There is no problem running the Ant target ‘generate-xsd’ from Ant. But I get an exception if I do it from gradle.

Im using gradle 2.14

Ant build file: build.xml

<?xml version="1.0" encoding="UTF-8" ?>
<project name="CAGenTUI2Forms" default="generate-xsd" basedir=".">

            <schema dir="${xsd-dir}" includes="*.xsd" />

    </target>
