When initial build fails, ibazel should exit

[alexeagle]

$ ibazel build //example:all
Error running Bazel exit status 7
Building //example:all
Files changed rebuilding...
ERROR: while parsing '//example:all': no such package 'example': BUILD file not found on package path.
INFO: Elapsed time: 0.182s
Build error: exit status 1
[ tool is now apparently hung ]

I think it's better to exit in this case (like iblaze does)

I've several times found myself writing while true; do iblaze build $target; done in order to try and fix up some vexing syntax errors (usually error prone yelling at me 😉). What would you think about bailing if the query fails but not if the build/test/run fails?

[alexeagle]

True, I've also found the asymmetry of bailing out after a failed build annoying. @mprobst do you have a strong case for that behavior?

[mprobst]

I think this should only fail if the query fails (i.e. if bazel-watcher doesn't know what to watch).

[alexeagle]

Here's a confusing case: I do
ibazel run :devserver
and there is a compile error. My devserver is not started. But, ibazel is still running.
Now I fix the compile error, ibazel reports success. But the devserver is still not running.

It feels like either ibazel should exit if first build is not successful, or else ibazel run should have a special case that it starts the binary on the first successful build.
