Github user minahlee commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/673#issuecomment-182632331 @FRosner Thank you for reporting it. Seems like you have misspelled `-` instead of `:`. It would be proper to have `com.databricks:spark-avro_2.10:2.0.1` instead of `com.databricks:spark-avro_2.10-2.0.1` Though I think there is a bug with toast notification since Zeppelin should some message in it something like this: <img width="1190" alt="screen shot 2016-02-10 at 3 08 03 pm" src="https://cloud.githubusercontent.com/assets/8503346/12965175/164c5b5e-d009-11e5-9187-d3581ce004c6.png"> It would be appreciated if you can share which browser you are using, and what log you can see in logs/zeppelin-{user}-*.log when you tries to save invalid maven coordinates
