Description

assertj-core , equalsverifier, rest-assured (and maybe other libraries) belong to testing (probably more). And they leaked to our "production" builds which depends on just 2 jars from James:

implementation "org.apache.james:james-server-jpa-guice:${jamesVersion}"
implementation "org.apache.james:james-server-cli:${jamesVersion}"

== Context

I'm working with David @dleangen on the self hosting with Apache James. We built a sandbox to play around and experiment: https://github.com/ieugen/james-self-hosting-sandbox .

Current setup is to use gradle + application plugin to build a custom distribution.
We build a zip distribution that pulls in all the dependencies including the offending ones used in testing.

The distribution has 137MB unpacked. files just James, without the JRE.

On initial inspection it seems there are test only dependencies that are being pulled as transitive dependencies of the 2 dependencies:
