Subject Error returned using <exec> task
Date Fri, 25 Jul 2008 14:08:43 GMT
Hi,

I am having an issue trying to execute the cvs command in an Ant script 
using the built in <cvs> task element.  In using this, I didn't know how 
to place the status information into a property.  So, I decided to use the 
<exec> task element.  Below is the code I am executing:

        <if>
            <or>
                <equals arg1="${os.name}" arg2="Windows 2000"/>
                <equals arg1="${os.name}" arg2="Windows XP"/>
            </or>
            <then>
                  <exec executable="cmd" failonerror="true" 
outputproperty="build.xml.version.line">
                       <arg line='/c "cvs status 
${quote}${app.lar.source.clientpath}/${prop.cust.xml.basename}.xml${quote} 
| findstr Working | findstr revision"'/>
                  </exec>
            </then>
            <else>
                  <exec executable="cvs" failonerror="true" 
outputproperty="build.xml.version.line">
                       <arg line="-d${common.setup.cvsRoot} status 
${app.lar.source.clientpath/${prop.cust.xml.basename}.xml | grep 
'Working'"/>
              </exec>
            </else>
        </if>
        <propertyregex property="build.xml.version"
              input="${build.xml.version.line}"
              regexp="([0-9\.]*)$"
              select="\1"
              casesensitive="false"
        />
        <echo message="XML file version info LINE = 
'${build.xml.version.line}'"/>
        <echo message="XML file version info = '${build.xml.version}'"/>

When I run the code, I get the following error:

        cvs.get.wfversion:
                [echo] 2008/07/25 09:00:22 Get CVS version information to 
generate the wfversion value.
                [echo] CVS Get the XML file version info: 
'${common.setup.source.clientpath}/Demo/Demo/Demo.xml'

        BUILD FAILED
 /scratch/srm/customer/build/CVSTest_ray/CustomerLar_build.xml:1364: 
Following error occured while executing this line
 /scratch/srm/customer/build/CVSTest_ray/CustomerLar_build.xml:498: exec 
returned: 1

I have been looking at the Ant book I purchased (Pro Apache Ant) and 
several websites for error codes returned from the <exec> task element, 
but have come up short.  As stated earlier, when I tried to use the <cvs> 
task element, I get stuck when I try to place the information into 
property.  Below is the code using the <cvs> task:

       <if>
            <or>
                <equals arg1="${os.name}" arg2="Windows 2000"/>
                <equals arg1="${os.name}" arg2="Windows XP"/>
            </or>
            <then>
                  <exec executable="cmd" failonerror="true" 
outputproperty="build.xml.version.line">
                       <arg line='/c "cvs status 
${quote}${app.lar.source.clientpath}/${prop.cust.xml.basename}.xml${quote} 
| findstr Working | findstr revision"'/>
                  </exec>
            </then>
            <else>
                  <cvs
                 cvsRoot="${common.setup.cvsRoot}"
                 command="status 
${app.lar.client.path}/${app.lar.client.source.filename} | grep 'Working'"
                 failonerror="true"
              />
            </else>
        </if>
        <propertyregex property="build.xml.version"
              input="${build.xml.version.line}"
              regexp="([0-9\.]*)$"
              select="\1"
              casesensitive="false"
        />
        <echo message="XML file version info LINE = 
'${build.xml.version.line}'"/>
        <echo message="XML file version info = '${build.xml.version}'"/>

At this point, I didn't know how to put the info returned into a property. 
 I know I could send it to a temp file, but I didn't want to add another 
step into the process.  Any help would be greatly appreciated.

Thanks,
