Re: trycatch and recursive make

Ok, thanks. I'll dig further into what's going on with make that it's so unhelpful :-)

Looks like the problem is with your make, which doesn't propagate the error

everything's peachy, so <exec> doesn't throw, and thus you don't <catch>
anything. --DD

Sorry about that. I actually do have failonerror set to false.
Here's the snippet of code I ran this time - basically I get the same results:

<target name="csrc" depends="init">
<exec executable="make" dir="${csrcDir}" failonerror="${failonerror}"
resultproperty="result" >
<arg line="-f Makefile.sun CSRC_ROOT=${csrcDir}
AGENT_ROOT=${basedir}"/>
</exec>
<echo message="Resultproperty is: ${result} />
</target>

If it fails immediately out of the exec I get:
csrc:

[exec] make: Makefile: No such file or directory
[exec] make: *** No rule to make target `Makefile'. Stop.
[exec] Result: 2
[echo] Resultproperty is: 2

Failures at a deeper level:
csrc:
[exec] make[1]: Entering directory
`/var/AccuRev_ws/marwks33_oriole_Plat_Int/agent/csrc/uagent/src'
[exec] make[1]: Leaving directory
`/var/AccuRev_ws/marwks33_oriole_Plat_Int/agent/csrc/uagent/src'
[exec] make[1]: Makefile: No such file or directory
[exec] make[1]: *** No rule to make target `Makefile'. Stop.
[exec] make[1]: Entering directory
`/var/AccuRev_ws/marwks33_oriole_Plat_Int/agent/csrc/arp/server'
[exec] make[1]: Makefile: No such file or directory
[exec] make[1]: *** No rule to make target `Makefile'. Stop.
[exec] make[1]: Leaving directory
`/var/AccuRev_ws/marwks33_oriole_Plat_Int/agent/csrc/arp/server'
[echo] Resultproperty is: 0

What I want to do with <catch> is get a uniform message into the logs when
we have failures - that makes parsing/manipulating them easier.

Thanks again...

Nolan

Strange. And without <trycatch>, what do you get? BTW, why can you just use

<exec executable="make" failonerror="false" resultproperty="result"/>

What do you really do in <catch>?

Also, I'm not sure resultproperty is set without failonerror="false"...

Subject: trycatch and recursive make

Hi,

As a part of our build process we are exec'ing a call to make ... which, in turn, calls make, which in turn calls make ... etc, etc, etc.

If the initial call to make from the build.xml fails trycatch catches the error and echos the correct message. If, however, make fails several levels down, trycatch doesn't return the "catch" message. Is there anyway to capture these errors from exec?

Here's the build.xml snippet:

<target name="csrc" depends="init">
<trycatch>
<try>
<exec executable="make" dir="${csrcDir}" resultproperty="result" >
<arg line="-f Makefile.sun CSRC_ROOT=${csrcDir} AGENT_ROOT=${basedir}"/>
</exec>
</try>
<catch>
<echo>CAUGHT MAKE FAILURE</echo>
</catch>

</trycatch>
</target>

The output if the exec of make fails immediately is the following:

csrc:
[exec] make: Makefile: No such file or directory
[exec] make: *** No rule to make target `Makefile'. Stop.
[trycatch] Caught exception: exec returned: 2
[echo] CAUGHT MAKE FAILURE
[echo] Resultproperty is: 0

If a failure occurs deeper down in the make structure all I get is the following:
csrc:
[exec] make[1]: Entering directory `/var/AccuRev_ws/marwks33_oriole_Plat_Int/agent/csrc/uagent/src'
[exec] make[1]: Makefile: No such file or directory
[exec] make[1]: *** No rule to make target `Makefile'. Stop.
[exec] make[1]: Leaving directory `/var/AccuRev_ws/marwks33_oriole_Plat_Int/agent/csrc/uagent/src'
[exec] make[1]: Entering directory `/var/AccuRev_ws/marwks33_oriole_Plat_Int/agent/csrc/arp/server'
[exec] make[1]: Makefile: No such file or directory
[exec] make[1]: Leaving directory `/var/AccuRev_ws/marwks33_oriole_Plat_Int/agent/csrc/arp/server'
[exec] make[1]: *** No rule to make target `Makefile'. Stop.
[echo] Resultproperty is: 0

Thanks for any help.

Nolan
