Is that the Watcher 2.0.0-beta1, or the ES one? ---

Hi Graham- I too got the similar error when my elasticsearch was 1.5 and trying to install the latest watcher plugin. I was able to get rid of that on another machine (Ubuntu) after installing the latest elasticsearch 1.7 and the latest watcher plugin. [https://download.elastic.co/elasticsearch/license/license-latest.zip](https://download.elastic.co/elasticsearch/license/license-latest.zip) [https://download.elastic.co/elasticsearch/watcher/watcher-latest.zip](https://download.elastic.co/elasticsearch/watcher/watcher-latest.zip) I followed the steps outlined in the below tutorial and was able to get the emails. The below link helped me a lot. > **[Learn instant Log Analytics and reporting using Elasticsearch, Logstash and...](http://hadooptutorials.co.in/tutorials/elasticsearch/real-time-alerting-using-elasticsearch-watcher.html)** > > Generating real time alerts using ElasticSearch Watcher Hope this helps. Thanks sudheer ---

I've tried this several times on a clean Ubuntu 14 with openjdk 8. 100% repro. My workaround is to move activation.jar and javax.mail.jar from plugins/watcher/lib to lib There is some sort of classloader issue going on here. ---

I have reproduced this on 2.x and filed an issue internally for tracking. ---
