Searching for nice coding kata sites I found this one – codingkata.org – I really liked because of the quick start and nice maven integration. Just head over to the kata overview select the kata you wish to try out, copy the generated maven command line option and run it in the console – heres the code for the hello-world sample: Coding Katas from Maven Archetype mvn archetype:generate -DinteractiveMode=false -DarchetypeRepository=http://www.codingkata.org/repo/release -DarchetypeGroupId=org.codingkata.template -DarchetypeArtifactId=solv-java-archetype -DarchetypeVersion=1.04 -DgroupId=org.codingkata.unit -DartifactId=hello-world-solv-java -DkataId=hello-world -DkataVersion=1.02 -DlangVersion=1.6 -DlibVersion=1.3.2 -Dversion=1271358 ...
