checking $? value

I have written a build script which creates a bin directory and compiles java code.
I call this build.sh in another script,dailybuild.sh ,I would like to test that the script ran correctly.
For this I used $?, but this value is turning out to be 1 instead of 0 even though the build.sh is correctly running.?Basically what I want to test is that the contents of build.sh ran properly-ie the code was compiled properly.
Is there a way to test that it ran correctly?
Thanks

$? returns the exit code of the command that was last run.

You need to check where build.sh is exiting that means the last command returned a nonzero exit code.

Start at the last instruction and do something like:
echo "command: xxxx | exit code: $?"
after it.

Keep adding echo commands until you realise which command is causing the problem.
