Maven Core Extensions Reference

  Maven core provides default {{{./extension.html}extensions}} as defined in <<</META-INF/maven/extension.xml>>>:

      "comment" : "We only test the multi-project here since for the monolithic project we would have no cache hits. This would mean we actually would test incremental compilation.",
      "coverage" : {
        "per_commit" : [ "linux" ]
      }
    } ]
  }, {

R8 / ProGuard
=============

If you use OkHttp as a dependency in an Android project which uses R8 as a default compiler you
don't have to do anything. The specific rules are [already bundled][okhttp3_pro] into the JAR which can be
interpreted by R8 automatically.

If you, however, don't use R8 you have to apply the rules from [this file][okhttp3_pro]. You might
also need rules from [Okio][okio] which is a dependency of this library.
