Could you add ability to use new version Scaladoc with old version Scala dependency? #499

Closed ReviveChan closed 2 years ago

ReviveChan commented 3 years ago

I'm using scala 2.11. Due to unsupported by some dependencies like flink or spark, I can't upgrade my scala version to newer version 2.13.

However I really like the new scaladoc style.

I tried to install scala 2.13 and just use its scaladoc to create my doc website through command line:

scaladoc -version # shows "Scaladoc version 2.13.6"
scaladoc -d doc/ src/main/scala/**/*scala

Then a 2.13 style scaladoc website was created.

So I think maybe it's ok to only use new version Scaladoc to create a doc-jar, without upgrading the whole Scala version in my project? Could scala-maven-plugin supports this usage?

Hi, not tested myself, but you could try to configure the goal scala:doc with an other version of scala. something like (need some tuning)

      <plugin>
        <artifactId>scala-maven-plugin</artifactId>
        <executions>
          <execution>
            <id>execution1</id>
            <goals>
              <goal>doc</goal>
            </goals>
            <configuration>
              <scalaVersion>2.13.6</scalaVersion>
            </configuration>
          </execution>

Thanks for your reply :)

I have tried to add the scalaVersion with 2.13.6, but it failed while running mvn scala:doc

I tried keep the scala-library version in maven dependencies with 2.11.12, or change it to 2.13.6, both failed. Error messages in that two situations are different.

However, I’m away from my computer now and I can’t remember the error details… I will run that again tomorrow.

It seems like the signatures of mutable.Set.apply in 2.11 and 2.13 are different, which causes the NoSuchMethodError. But I don't know why the error occurred only with mvn scala:doc...

Closing. I don't think this is something we'll ever tackle.
