Dotty project Directory rockthejvm-examples\ contains Scala 3 code examples coming from Ciocîrlan's blog Rock The JVM.

Code examples presented below can be built/run with the following tools:

Build tool Build file(s) Parent file(s) Environment(s)
ant.bat build.xml build.xml, ivy.xml Any a)
cmd.exe build.bat
(build.properties)		 cpath.bat b) Windows only
sh.exe build.sh
(build.properties)		 Cygwin/MSYS2/Unix only
make.exe Makefile Makefile.inc Any
mvn.cmd pom.xml pom.xml Any
sbt.bat build.sbt n.a. Any
a) Here "Any" means "tested on Windows, Cygwin, MSYS2 and Unix".
b) This utility batch file manages Maven dependencies and returns the associated Java class path (as environment variable).
