Error trying to compile Kurento Java tutorial [maven dependency resolution]

After trying the following as specified on the kurento website,

git clone https://github.com/Kurento/kurento-tutorial-java.git
cd kurento-tutorial-java/kurento-one2one-call-advanced
mvn compile exec:java

I get an error like :

Failed to execute goal on project kurento-client: Could not resolve dependencies for project org.kurento:kurento-client:jar:6.1.1-SNAPSHOT: The following artifacts could not be resolved: org.kurento:kurento-jsonrpc-client:jar:6.1.1-SNAPSHOT, org.kurento:kurento-jsonrpc-server:jar:6.1.1-SNAPSHOT, org.kurento:kms-api-core:jar:6.1.1-SNAPSHOT, org.kurento:kms-api-elements:jar:6.1.1-SNAPSHOT, org.kurento:kms-api-filters:jar:6.1.1-SNAPSHOT: Could not find artifact org.kurento:kurento-jsonrpc-client:jar:6.1.1-SNAPSHOT ->

How best can i resolve such a dependency issue ?

Solution

You have checked out the development version of the tutorials, 6.1.1-SNAPSHOT, which depends on other development versions of kurento artifacts. Those artifacts are not published in maven central, so you have three options here

Check out kurento-java and all related projects, such as kurento-module-creator and a bunch more. You can pull the thread from the pom, they are about 5 projects. You'll have to compile and install all of them in your local .m2 repository
Use our internal archiva repository
Checkout a tag containing a release version (i.e. git co 6.1.0)

In any case, the version of the tutorials should match the version of your KMS, so if you are using a development version of KMS, please use the development version of the tutorials. But if you are using a stable version of KMS, you should be using the matching release version of the tutorials.
