I am finding that the sourcepath for javadoc:jar (when run as part of the release profile) is different from the sourcepath for javadoc:javadoc in my project that involves (protoc-) generated sources.
(The net effect is that at release time, everything works fine up until release:perform, which fails (!) during the attach-javadocs execution I've configured following the documentation ( https://maven.apache.org/plugin-developers/cookbook/attach-source-javadoc-artifacts.html#Configuring_Maven_Javadoc_Plugin) ). I have a <pluginManagement> stanza centralizing my maven-javadoc-plugin configuration that does not mention sourcepath in any way. mvn help:effective-pom -Prelease shows exactly what I would expect, and no additional maven-javadoc-plugin configuration. Somehow, the sourcepath for javadoc:javadoc has the generated-sources directory in it; the sourcepath for javadoc:jar does not. Here is the pluginManagement section (it's quite ordinary): <plugin> <artifactId>maven-javadoc-plugin</artifactId> <version>3.0.0-M1</version> <configuration> <doclint>-missing</doclint> </configuration> </plugin> When I run mvn -X javadoc:javadoc and inspect the options file, I see this: -sourcepath '/Users/ljnelson/Projects/frob/src/main/java: */Users/ljnelson/Projects/frob/target/generated-sources/protobuf/java:/Users/ljnelson/Projects/frob/target/generated-sources/protobuf/grpc-java* :/Users/ljnelson/Projects/frob/src/main/javadoc' When I run mvn -X javadoc:jar and inspect the options file, I see only this: -sourcepath '/Users/ljnelson/Projects/frob/src/main/java:/Users/ljnelson/Projects/frob/src/main/javadoc' The javadoc:jar goal outputs a bunch of warnings. When I run it locally (mvn javadoc:jar), they show up as warnings. When it is run as part of the maven-release-plugin's perform goal, it fails the build. I'm at a loss as to how to go about fixing this. Is it, perhaps, the job of the plugin in charge of generating the sources to do something here? Best, Laird
