This project is based on Maven. You can use both Intellij or Eclipse for it. It is being developed in Linux so all the assembling scripts are in bash. In order to assemble the dist with zip archives just run ./ and it will create a dist folder with both binary and source folders and it will prepare zip archives there as well. If you want to quickly test the concept and install galen right after the assembling you can use script ./ It uses and then just invokes sudo ./


There are two levels of testing. The first one is just the regular mvn clean test. But as there is a lot of Javascript code - you need Mocha. The tests can be directly executed via maven by using npm under the hood. If you have npm installed then you can just simply run mvn test command and that will trigger Jslint tests, Mocha tests and Java TestNG tests.
