Mars Hall created PIO-99:
----------------------------
Summary: `pio build` exits successfully even when compilation fails
Key: PIO-99
URL: https://issues.apache.org/jira/browse/PIO-99
Project: PredictionIO
Issue Type: Bug
Components: Build
Affects Versions: 0.11.0-incubating
Reporter: Mars Hall
The build command does not fail as expected. While not a big deal when working
locally, it seems like this could be problematic for automated, continuous
build/integration workflows.
{code}
$ pio build
…
[ERROR] [Engine$] [error] one error found
[ERROR] [Engine$] [error] (compile:compileIncremental) Compilation failed
[ERROR] [Engine$] [error] Total time: 5 s, completed Jun 21, 2017 9:59:55 AM
[ERROR] [Engine$] Return code of build command:

It certainly appears successful at the end, and exit code was {{0}}.
Looking back for the error is not hard, but this behavior is problematic when
composing {pio build} command into a shell script.
