On maven central all 4.x.x versions have empty javadocs jar with size of 261 bytes. For example, version 4.0.0 https://repo1.maven.org/maven2/com/squareup/okhttp3/okhttp/4.0.0/okhttp-4.0.0-javadoc.jar (261 bytes) Same for 4.7.2 https://repo1.maven.org/maven2/com/squareup/okhttp3/okhttp/4.7.2/okhttp-4.7.2-javadoc.jar And latest ATM 4.11.0 https://repo1.maven.org/maven2/com/squareup/okhttp3/okhttp/4.11.0/okhttp-4.11.0-javadoc.jar Versions 5.x.x looks ok, but they are in alpha ATM https://repo1.maven.org/maven2/com/squareup/okhttp3/okhttp/5.0.0-alpha.9/okhttp-5.0.0-alpha.9-javadoc.jar. So all 4.x.x branch is missing javadocs.
