Where is the maven dependency org.apache.toree.kernel ?

[MarineRu]

I want to create a eclairjs-node and so, I need to create a eclairjs-nashorn.

I installed Jupyter and Apache Toree.

I executed these commands :
git clone https://github.com/EclairJS/eclairjs-nashorn.git
cd eclairjs-nashorn
sudo mvn package

But I have this error for mvn package :
[ERROR] Failed to execute goal on project eclairjs-nashorn: Could not resolve dependencies for project org.eclairjs:eclairjs-nashorn:jar:0.8-SNAPSHOT: The following artifacts could not be resolved: org.apache.toree.kernel:toree-kernel-api_2.11:jar:0.1.0.dev1-incubating-SNAPSHOT, org.apache.toree.kernel:toree-kernel_2.11:jar:0.1.0.dev1-incubating-SNAPSHOT: Failure to find org.apache.toree.kernel:toree-kernel-api_2.11:jar:0.1.0.dev1-incubating-SNAPSHOT in https://repository.apache.org/content/groups/snapshots was cached in the local repository, resolution will not be reattempted until the update interval of apache-snapshots has elapsed or updates are forced -> [Help 1]

I searched the maven dependency in https://mvnrepository.com but I didn't find org.apache.toree.kernel.

Can I have some help please .... ?
