i want to export variable from ant script, but i am doing something wrong cause I get error:
sh: 0: Can't open export DISPLAY=:10
There is fragment of my script
<target name="xvfb_start">
<echo>Starting xvfb</echo>
<exec executable="sh">
<arg value="export DISPLAY=:10"/>
</exec>
</target>
This doesn't work because sh expects the first argument to be a command to execute. export DISPLAY=:10 is no valid command (and since you pass this to sh as a single argument, it takes everything to be part of the script name to start, even the spaces and colon).
To make sh evaluate the arguments, try sh -c. That will give you a shell which has the variable DISPLAY defined. Since no further commands are on the command line, the shell will terminate and your variable will be lost with it.
Solutions:
For #1:
<exec executable="sh">
<arg value="-c"/>
<arg value="export DISPLAY=:10 ; xvfb"/>
</exec>
For #2, put all the commands into a normal shell script and have sh execute that.
An approach I've found helpful is to export the variable in the same command as running ant.
For example (from your shell):
export DISPLAY=:10 ; ant your-target-name
It's also the case that any variables exported in your ~/.bashrc (if you have one) will be available to processes that ant runs. I have my export DISPLAY in there on my project. (If you're testing this, don't forget to call reset to get your terminal to pick up the changes to .bashrc).
