Usage

QuickStart

export JAVA_HOME=/usr/lib/jvm/default   # which JDK version should be used?
mvn package                             # build jar from source
java -jar target/package.jar            # run compiled src

Goals

Maven is composed of goals. You run goals by passing them on the commandline (like a makefile targets). You can also build your own goals.

common goals

# run tests
mvn test
mvn test -Dtest=AppTest           # run specific module
mvn test '-Dtest=*Test'           # match modules
mvn test '-Dtest=*#test_*_equal'  # match methods

# compile/run
mvn \
    compile \
    exec:java -Dexec.mainClass=com.example.pkg.App

# create jar
mvn package
