What is Zinc

Zinc is a standalone version of the incremental compiler for sbt GitHub page. Providing a “warmed-up” JVM it increases compilation speed. The scala-maven-plugin allows us to take advantage of incremental compilation from a Maven build.

Follow the link on the Zinc GitHub page to download latest stable version and install.

Running zinc

cd $ZINC_DIR/bin
./zinc -scala-home /usr/local/scala-2.10.4 -start
./zinc -status       #After compilation shows cached setup
./zinc -shutdown
