Class file for org.apache.http.entity.mime.MultipartEntityBuilder not found in Pact 4.2.12

[cberg-zalando]

We have a project built with Gradle 7.1.1 using

• au.com.dius.pact.provider:junit5
• au.com.dius.pact.provider:spring
• au.com.dius.pact.consumer:junit5

as dependencies. Until Pact 4.2.11 everything was fine, but when dependabot suggested the updated to 4.2.12 our build started failing with class file for org.apache.http.entity.mime.MultipartEntityBuilder not found when calling PactDslWithProvider::body with a PactDslJsonBody instance.

I traced it down to the new feature of allowing to pass an org.apache.http.entity.mime.MultipartEntityBuilder from theorg.apache.httpcomponents:httpmime library, which is a dependency of the au.com.dius.pact:consumer library. This library also uses Gradle and defines the httpmime library via implementation scope, which according to Gradle's documentation says, that it will not be exposed to the actual library consumer. The JUnit5 consumer pulls that library in via api scope, but I assume, that Gradle does not apply the scope widening to the dependencies of the pulled in dependency resulting in the httpmime library being unavailable during the test compilation.

Ah, MultipartEntityBuilder is not in the main Apache HTTP library. I'll add that as an api dependency.
