How to run multiple commands from ant exec task

问题:

I want to run two dos commands from Ant exec task.

I have tried below code

<exec dir="${testworkspace}\${moduleName}" executable="cmd" failonerror="true" output="${testworkspace}\${moduleName}\BuildConsole_TC${tc_num}.log" resultproperty="execrc">
                    <arg value="/c echo Download Status is ${DownloadStatus}"/>
                    <arg value="/c Load.bat ${moduleName} ${Intapp} ${CcvStatus}"/>
                </exec>

but it executes only first command and skips second. I am trying this on windows OS.

回答1:

This should work. Simply chaining the commands.

<exec dir="${testworkspace}\${moduleName}" executable="cmd" failonerror="true" output="${testworkspace}\${moduleName}\BuildConsole_TC${tc_num}.log" resultproperty="execrc">
    <arg value="/c echo Download Status is ${DownloadStatus} &amp; Load.bat ${moduleName} ${Intapp} ${CcvStatus}"/>
</exec>

Why do you need to run two commands in a single <exec> task? Instead, just use a second <exec> task. You can include both in a single target:

 <target name="execute.this">
     <exec dir="${testworkspace}\${moduleName}" 
         executable="cmd" failonerror="true" 
         output="${testworkspace}/${moduleName}/BuildConsole_TC${tc_num}.log" 
         resultproperty="execrc">
         <arg value="/c echo Download Status is ${DownloadStatus}"/>

     <exec dir="${testworkspace}\${moduleName}" 
         executable="cmd" failonerror="true" 
         output="${testworkspace}/${moduleName}/BuildConsole_TC${tc_num}.log" 
         resultproperty="execrc">
         <arg value="/c Load.bat ${moduleName} ${Intapp} ${CcvStatus}"/>
     </exec>

Or better yet, just use the <echo> task:

     <echo message="/c echo Download Status is ${DownloadStatus}"/>
     <exec dir="${testworkspace}\${moduleName}" 
         executable="cmd" 
         failonerror="true" 
         output="${testworkspace}/${moduleName}/BuildConsole_TC${tc_num}.log" 
         resultproperty="execrc">
         <arg value="/c Load.bat ${moduleName} ${Intapp} ${CcvStatus}"/>
     </exec>

If you need the output of the echo task in the same file, you can use the file parameter in the echo command, and the append parameter in the exec task.
