mvn in bash script if statement

Question

I want to run the command mvn clean in a bash script. But I want to put it in an if statement. If the clean does not run properly I would like to exit out of the bash script wit

Answer 1

I prefer to use a variable to capture the return code. Improves readability and allows running additional commands without fear of clobbering return code value:

mvn clean

MVN_RTN=$?
if [ "${MVN_RTN}" -ne 0 ]; then
   echo "Maven returned failure code ${MVN_RTN}"
   exit 1
