Subject Exec task: Args not passed to task
Date Mon, 28 Apr 2008 07:20:00 GMT
Hi, I'm migrating an app from Ant 1.6.1 to Ant 1.7.0, and I have problems
with exec tasks. Ant execute task without passing arguments to process!

For example, I have this task definition:

<project name="permision" default="permision"  basedir=".">

        <property name="timeout" value="120000" />

        <target name="permision">

                <echo message="Modify directories permissions ${path}, mask
${dirMask}" />

                <exec executable="chmod"
                          timeout="${timeout}"
                          failonerror="true">

                        <arg line="-R ${dirMask} ${path}" />

                </exec>

                <echo message="Modify files permissions ${path}, mask
${fileMask}" />

                <exec executable="/data/bin/ant/permisions.sh"
                          timeout="${timeout}"
                          failonerror="true">

                        <arg line="${path} ${fileMask}" />

                </exec>

        </target>

</project>

An easy one, and works ok with Ant 1.6, as you can see in logs:

(...)

With Ant 1.7.0 I get this log:

Ant task isn't receiving parameters!

This task are executed using Ant's java api. If I execute task manually, all
goes ok too. And if I use deprecated <exec command, all goes fine too!

Someone have an idea what's happening here? Thanks in advance!
