kafka-web-console

Hi, all

I am installing kafka-web-console on ubuntu server, when I sbt package it, it stuck on waiting for ivy.lock

root [ at ] DO-mq-dev:/home/stuser/kafkaprj/kafka-web-console# sbt package
Loading /usr/share/sbt/bin/sbt-launch-lib.bash
[info] Loading project definition from /home/stuser/kafkaprj/kafka-web-console/project
Waiting for lock on /root/.ivy2/.sbt.ivy.lock to be available...

any idea? and any suggestion while further install.

thanks

Alec
