PostPosted: Fri 16 Sep '16 16:07    Post subject: basic question about SBT Reply with quote

in my compilation even though i am placing twitter jar files in the src/main/resources folder ,but SBT compilation is not picking them up and compiles and package without errors but at run time gives me error as "class not found twitterUtils"

my question is why SBT is not including the jar files from resource folder in the compilation ?

people are telling me to do all these complex steps of getting the Git utility and then doing a sbt assembly which I did but since iam behind proxy Git is not working even though all the http_proxy setup.

I have also tried putting these twitter jar files in the CLASSPATH with no luck.

I am stuck with this issue so any help is highly appreciated.

please see the details below :
