You should use our maven wrapper (./mvnw) script to
get a more consistent build result. It should auto
download the correct version of Maven tool if you do not already
have one.
To compile:
export JAVA_HOME=/path/to/jdk8
./mvnw compile
To build distribution package
./mvnw package
# Or if you want to skip tests
./mvnw package -DskipTests
Note
The final combined single jar is found under quartz/target/quartz-<version>.jar
