Executing Maven task from shell script and getting

Question

I'm executing a Maven deploy task from a bash script however even if the Maven task fails the script will continue and complete without errors.

I have tried the -e flag but that causes the deploy to fail. I also tried the following (pseudo code)

result_code= mvn deploy
if [$result_code -gt 0];then
exit 1

Any suggestions how i can identify if the deploy was successful?

Answer 1

result_code=mvn deploy is not the way to get return status

you can try e.g. :

#!/bin/bash
mvn deploy
STATUS=$?
if [ $STATUS -eq 0 ]; then
echo "Deployment Successful"
else
echo "Deployment Failed"
fi

In addition if anyone using Windows 10, here is the example which I use:

mvn deploy
if not %ERROR_CODE%==0 goto error

echo SUCCESS
goto end

:error
echo FAILED

:end

Answer 3

Just one other possible reason a person's mvn task may return 0 despite failing: be careful about piping the output of maven to other programs. For example, I'm using grcat (which grc is build on top of), which will always return exit code 0;

\mvn compile | grcat ~/conf.mvn

I'm not sure how to retain my nice color coding of the output. There is color_maven.sh out there but that has other issues.
