I can't run the windows 'start' using ant exec. Ant version 1.7.1.
Here is sample build.xml to recreate the problem
<project name="test" basedir="." default="test-target">
<target name="test-target">
<exec executable="start">
<arg line="cmd /c notepad" />
</exec>
</target>
</project>
getting the following error when I execute this build file:
Execute failed: java.io.IOException: Cannot run program "start": Cre
ateProcess error=2, The system cannot find the file specified
My env is Windows XP, Ant 1.7.1 I am trying to run this from DOS prompt. I rule out any PATH related issues, as I could run 'start cmd /c notepad' from DOS promt manually.
Any suggestions on how to fix this?
cheers a s
start is not an executable but is an internal command of the cmd.exe shell, so to start something you'd have to:
<exec executable="cmd.exe">
<arg line="/c start notepad" />
</exec>
EDIT:
For spawning multiple windows, this should work:
<target name="spawnwindows">
<exec executable="cmd.exe" spawn="yes">
<arg line="/c start cmd.exe /k echo test1" />
</exec>
<exec executable="cmd.exe" spawn="yes">
<arg line="/c start cmd.exe /k echo test2" />
</exec>
</target>
but you mentioned that spawn="true" is not applicable for your environment, why is that?
my solution
<project name="test" basedir="." default="test-target">
<target name="start-init">
<exec executable="where" outputproperty="START">
<arg line="start" />
</exec>
</target>
<target name="test-target">
<exec executable="${START}">
<arg line="cmd /c notepad" />
</exec>
</target>
</project>
