NoSuchFieldError: TRACE when used with elasticache.

[timscarborough]

When setting the app dependency for play2-memcached with AWS elasticache as described in the readme, I get a NoSuchFieldError: TRACE when running my application. I have the AWS elasticache client jar in my lib folder and I excluded net.spy as described in the documentation ("com.github.mumoshu" %% "play2-memcached" % "0.5.0-RC1 exclude("net.spy", "spymemcached")). Am I missing something? Any assistance would be greatly appreciated. Thanks!

Same here. I am using version 0.6.0 with play 2.3.3.
Problem seems related to the logging mechanism of net.spy.memcached. I also tried to upgrade spymemcached to the newest release 2.11.4. The error remains.

Could identify the problem. The Amazon ElastiCache library serves an outdated Logger implementation that is not compatible with the updated Memcached Play Plugin (particularly the class net.spy.memcached.compat.log.Level).

I created a fork of the Amazon ElastiCache library and updated the logging related files and corresponding dependencies: https://github.com/mugglmenzel/aws-elasticache-cluster-client-memcached-for-java
Feel free to clone to compile with ant. Will also trigger a pull request.

AWSlabs fixed it in this commit awslabs/aws-elasticache-cluster-client-memcached-for-java@730fe4f
and it is available in the latest release 1.1.0 https://github.com/awslabs/aws-elasticache-cluster-client-memcached-for-java
