问题
I'm trying to use play2-elasticsearch plugin for playframework2 version 2.1.3 I have just done exactly the github example says, the only modification was to change this line to use the server on the local ip address.
elasticsearch.client="127.0.0.1:9300"
but when i try to run the example i get the following exception, any idea? I'm using play framework 2.1.3 on mac with jdk1.7

回答1:
From the stack trace, it seems that you use the 0.5.4 version which is not compatible with play 2.1.3 (only with play 2.1.0).
If you look at the "versions" table in the README file, you will see that the 0.7-SNAPSHOT version is required if you use play 2.1.3. Try to use this one.
