Hi we are using Jclouds v. 1.9.1.We try to use the router api from
org.jclouds.openstack.neutron.v2.extensions.
Following the code that we use:
1 Optional<RouterApi> t = neutronApi.getRouterApi(region);2
routerApi =t.get();
but we have the following error:
Exception in thread "main"
com.google.common.util.concurrent.UncheckedExecutionException:
