This example covers simple use cases and is runnable as Java App or just using Maven “test” goal (as there is a Junit test simply executing the main() method, to not have to fuss with classpath etc.)
Try following steps:
$ cd indexer-examples $ mvn clean test -Pexamples ... first run will take few minutes to download the index, and then will run showing some output $ mvn test -Pexamples ... (no clean goal!) second run will finish quickly, as target folder will already contain an up-to-date index
Please, note that the tests in this module will only compile by default; the will not be executed, unless you activate the profile (-Ptests).
Have fun,t
