cd piflow-core mvn test -DskipTests -PstartServer
Since piflow-shell depends on piflow-core, so install piflow-core project first:
cd piflow-core mvn clean install -DskipTests
Then, run mvn with following arguments:
cd ./piflow-shell mvn clean test -PrunShell
Now, piflow-shell will be started in which you can type commands:
πFlow> SeqAsSource(1 to 1000) > DoMap[Int, Int](_ + 1) > ConsoleSink() πFlow> res0!
:quit to quit the shell.
