Stub runner jar is >100MB

[dsyer]

I can't believe every user of the stub runner wants all the features if it's that big. What is it taking up so much space anyway? Maybe we could make it a thin jar or something?

[marcingrzejszczak]

Which stub-runner jar are we talking about? The stub runner boot (the standalone one) or the stub runner dependency?

Example: https://repo1.maven.org/maven2/org/springframework/cloud/spring-cloud-contract-stub-runner-boot/2.2.2.RELEASE/

Ok so we're talking about the fat-jar. This is the standalone stub runner application. I'd need to do a full dependency analysis but I don't see anything obvious oob (https://github.com/spring-cloud/spring-cloud-contract/blob/v2.2.2.RELEASE/spring-cloud-contract-stub-runner-boot/pom.xml#L16-L29)

[marcingrzejszczak]

Kotlin could be added as an optional dependency but then it won't be able to read in kotlin DSLs. We would have to give the user an option to read kotlin at runtime. So thin jar would be the answer I guess

[marcingrzejszczak]

We'll convert stub runner boot to become a thin jar based jar
