Hi, this is Masaki Mizobuchi.
I faced the below error when I build the projects. So, I report is.

Unknown host repository-estatio.forge.cloudbees.com is shown when I execute the commnad mvn eclipse:eclipse.
It seems that [(http://repository-estatio.forge.cloudbees.com/snapshot/)] is closed host.

Error message is below.

[ERROR] Failed to execute goal on project naked-objects-fixture: Could not resolve dependencies for project com.iluwatar:naked-objects-fixture:jar:1.22.0-SNAPSHOT: Could not transfer artifact com.iluwatar:naked-objects-dom:jar:1.22.0-SNAPSHOT from/to Cloudbees snapshots (http://repository-estatio.forge.cloudbees.com/snapshot/): repository-estatio.forge.cloudbees.com: Unknown host repository-estatio.forge.cloudbees.com -
