Connection Refused error when running Sbt Tests in Jenkins but it works fine in local machine

[Vijaykumar Gundavarapu]

Hi,

I have a simple Jenkins job which executes some Sbt tests in scala/akka and it tries to download Mongo flapdoodle to execute a test.

The tests works fine in local machine but I get connection refused error when it runs in Jenkins.

Anyone has any idea why this happens?

I would recommend logging in to where Jenkins is trying to run sbt, cd-ing to the workspace and trying to run sbt yourself from the command line. Take Jenkins out of the loop. Maybe you might have a proxy issue on the slave/master where you are running sbt.
