Subject Re: Google Compute Engine Load Balancing Support for Stratos - GSoC 2015

Hi Asanka,

I found following errors in your log:

[ERROR]
/home/sanjaya/myStratos/stratos/extensions/cep/stratos-cep-extension/src/main/java/org/apache/stratos/cep/extension/SecondDerivativeFinderWindowProcessor.java:[51,1]

It looks like the CEP extension module cannot find some of the classes in
Siddhi library. Can you please check whether you can find the following
artifact in your local .m2 repository?

<groupId>org.wso2.siddhi</groupId>
<artifactId>siddhi-core</artifactId>
<version>2.0.0-wso2v5</version>


Thanks
