Question

I have an exiting ant build that is called via ant -lib lib -f test_build.xml

I wanted to add one more <target> section to be run after the existing one finishes. I did some research and found ant manual for exec and even a question here on SO. After some reading I added new target to this existing build but it didn’t work.

I tried to create new build file only with my target. It doesn’t work either. Although the ant run finishes with message BUILD SUCCESSFUL
Total time: 0 seconds

If I run my ruby script from a command line it works. I tried to create bat file that would call my ruby script with the same result. If I call the bat file from dos window it works.

My ant run build file looks like

<project name="RunRubyExample">

<target name="calling ruby " >
  <exec executable="ruby.exe">
    <arg value="C:\EduTester\others\afterant.rb 1 2 tri four"/>
  </exec>
</target>

<target name="calling batach">
  <exec executable="cmd">
    <arg value="/c"/>
    <arg value="C:\EduTester\others\rubruby.bat 1 2 tri four"/>
  </exec>
</target>

</project>

It looks like you’re passing a single arg value with embedded spaces

<arg value="C:\EduTester\others\afterant.rb 1 2 tri four"/>

Is that right? Or should it be either an arg line:

<arg line="C:\EduTester\others\afterant.rb 1 2 tri four"/>

or multiple arg values:

<arg value="C:\EduTester\others\afterant.rb"/>
<arg value="1"/>
<arg value="2"/>
<arg value="tri"/>
<arg value="four"/>
