Unable to publish sbt plugin to sonatype due to missing javadoc

[Matthew de Detrich]

Describe the bug
When publishing an sbt plugin to sonatype I get the following error

2022-03-11 14:34:15.198Z error [SonatypeClient] [close] Failed  - (SonatypeClient.scala:182)
2022-03-11 14:34:15.198Z error [SonatypeClient] Activity name:close, started:2022-03-11T14:34:00.755Z  - (SonatypeClient.scala:458)
2022-03-11 14:34:15.200Z error [SonatypeClient]     Failed: javadoc-staging, failureMessage:Missing: no javadoc jar found in folder '/com/lightbend/paradox/sbt-paradox-project-info_2.12_1.0/1.1.9'  - (SonatypeClient.scala:376)

This is even when using

ThisBuild / Compile / doc / sources := Seq()

(see #30 (comment))

Project had Compile / packageDoc / publishArtifact := false in the build.sbt which I didn't notice, removing it fixed the problem.
