Invalid JVM version error message is handled in the scripts

[erichaagdev]

Adds specific error handling for an invalid JVM version. Other non-zero exit codes are treated as an unexpected error.

Testing

Below are all of the test cases I ran to verify these changes.

Running with -x and Java 8

$ java -version            
openjdk version "1.8.0_362"
$ ./03-validate-local-build-caching-different-locations.sh -r [email protected]:gradle/ge-solutions.git -p sample-projects/gradle/8.x/ge -t 'build' -x

This results in the following:

Running with -x, Java 8, and setting CLIENT_JAVA_HOME

$ java -version            
openjdk version "1.8.0_362"
$ CLIENT_JAVA_HOME="$JDK17" ./03-validate-local-build-caching-different-locations.sh -r [email protected]:gradle/ge-solutions.git -p sample-projects/gradle/8.x/ge -t 'build' -x

This results in the following:

Running with -x and Java 17

$ java -version
openjdk version "17.0.6" 2023-01-17
$ ./03-validate-local-build-caching-different-locations.sh -r [email protected]:gradle/ge-solutions.git -p sample-projects/gradle/8.x/ge -t 'build' -x                                 

This results in the following:
