 Posted: Wed Dec 30, 2009 4:38 pm Post subject: What's the best way to debug Ant? |
 |
|
Hi.
I have a large Java project with its own Ant script that was written for it. The build is initiated from outside the Ant script by a batch file which sets up some environment variables (needed during the build to locate libraries, special files, etc.) and then invokes the deploy target in the build script.
I know debugging of Ant scripts can be done by right-clicking on the build script and clicking debug target. The problem for me is if I debug this way, my environment variables are not carried into the debugging session. For instance, when the debugger hits this line:
| Code: | | <property name="SOME_VAR" value="${env.SOME_VAR}"/> |
where we're essentially assigning a system environment variable to a local Ant variable, the build fails. I tried to remedy this problem by invoking the shell script as the first thing done in the build like so:
| Code: | <exec dir="." executable="cmd" os="Windows NT">
<arg line="/c build_vars.bat"/>
</exec> |
which seems to call the script correctly but when it hits the above line that assigns an env variable to a local variable, the literal string "${env.SOME_VAR}" is assigned to the variable instead of the value of that variable (say "TRUE").
How can I resolve these environment variables correctly so that I can debug my Ant script? Thanks for your help. |
