Hi,
we had a lot of fun debugging our nightly builds in the last couple of days.
Part of our build process are some programs that get build using Apache Maven
and are used to generate other files later on. It's something like this:
ADD_CUSTOM_COMMAND(
OUTPUT ${artifact}
DEPENDS ${sources}
WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
COMMAND ${MAVEN_EXECUTABLE} --quiet install
COMMENT Building Java artifacts using Apache Maven...
VERBATIM
)
ADD_CUSTOM_TARGET(${target} ALL DEPENDS ${artifact})
And then some other ADD_CUSTOM_COMMANDS that depend on ${target}. When this
was run on any of our desktops it worked fine, when we log in to the build
machines it works fine, but when it runs with cron it doesn't work (not even
on the Windows hosts). Since the first errors we got in CDash log were those
of the target files that could not be generated because the maven output was
missing we suspected some sort of dependency problem. It took us a while to
find out that the dependencies were fine and Maven really wrote out some
errors but CTest just didn't catch them. At the end it was just JAVA_HOME
environment not being set when running with cron (easily fixed by source
/etc/profile in the nightly script).
To prevent other people wasting their time hunting bugs that are simply not
there: here is a small patch that tells CTest to detect Mavens error and
warning messages.

Subject: [PATCH] CTest: catch warning output of Apache Maven
Some samples of things that got unnoticed by our nightly builds:
$ JAVA_HOME= mvn
Warning: JAVA_HOME environment variable is not set.
...
$ mvn
