Seems like python doesn't find the script (because there is no error
message).
Possible solutions:
- use absolute path for script location:
<arg value="${basedir}/install/tools/jsmin.py"/>
- call script directly (like your working test.py):
<exec executable="${basedir}/install/tools/jsmin.py"
resolveexecutable="true">
<arg value="</var/www/hv/lib/proj/build/proj-all.js>"/>
<arg value="/var/www/hv/lib/proj//build/proj-all-min.js"/>
</exec>
I also note the double slash in the last argument.
Cheers,

Hi Luis,
Thanks for the suggestion. I had tried using "ant -v" before, and also
redirecting the output, but was not aware of the '-d' parameter.
The script *should* result in a new file, "proj-all-min.js" being created.
The file is only created when I run the script manually, however,
and not when I call the script during an Ant build.
Here is the relevant section of my build.xml as well as the complete output
from execution:
========= BEGIN build.xml ===============
<project name="proj" default="build" basedir="../">
.
.
.
<target name="build">
<!-- create build directory -->
<mkdir dir="lib/proj/build"/>
<!-- test -->
<exec dir="install" executable="test.py" resolveexecutable="true"/>
<!-- minify -->
<exec dir="./" executable="python" resolveexecutable="true">
<arg value="install/tools/jsmin.py"/>
<arg value="</var/www/hv/lib/proj/build/proj-all.js>"/>
<arg value="/var/www/hv/lib/proj//build/proj-all-min.js"/>
</exec>
========= END build.xml ===========
Note: Ant is run from /install, and thus "../" points to the project's root
directory.
The relevant python script is located in /install/tools, and
"test.py" is a dummy
script located in /install that I used to test a simple case of
script execution.

Any ideas?

Hi,
need more info to help you. Use "ant -d" to get the command line and the
arguments how python is called. How exactly does it not work? Any error
message?
Cheers,

Hi all,
I've just recently started using Ant on Linux, and so far it has been
really
amazing. I've run into
one problem, however, that I haven't been able to get past.
I would like to call an external script (a python script to minimize some
JavaScript files),
but have not been able to get it to execute properly. I searched around
some, and found
an earlier thread (http://marc.info/?l=ant-user&m=115078380228196&w=2)
where someone with a similar problem was able to fix things setting
"resolveexecutable" to true.
This works for me when I try running a dummy script with no arguments,
e.g:
...
<exec dir="./" executable="test.py" resolveexecutable="true"/>
...
[exec] Hello World
When I try and do something requiring command-line arguments though I
can't
get it to work:
<exec dir="./" executable="python" resolveexecutable="true">
<arg value="install/tools/jsmin.py"/>
<arg value="<${libs}/build/test.js>"/>
<arg value="${libs}/build/testl-min.js"/>
</exec>
I've tried executing both "python" (and passing the scripts name as an
argument), and the script itself.
Nothing seems to work. The command executes fine from the command-line,
and
what even more, when
I print the arguments passed to the python script using argv, and then
string them together and run them
it works fine, but still no luck when I try to get it working through ant.
Anyone have any suggestions as to what might be the problem?
Any help would be greatly appreciated.
Thanks,
Keith
