When cross-building is enabled, the code is generated only for one version

In my SBT project, my main Scala version is set to 2.11.8, but because I am also using Spark, I set up my project for cross-building for 2.10.6 and 2.11.8.

However, the +avro:generate-specific (the plus for crossbuild mode) puts the generated Scala code to target/scala-2.10/src_managed/main/compiled_avro. I manually have to copy it to the respective scala_2.11 folder.

Without the copying, a sbt +compile works, but when using the project in Eclipse, I manually have to add the 2.10 folder to my project, otherwise it shows a lot of compiler errors.

Is it possible to tell the plugin to output the generated code to both directories?

We’ve been having this issue where sometimes the 2.12 compilation would run first and things would succeed (Scala 2.13 seems to be happy compiling with the 2.12 code) but the other way around things fail (2.12 is very unhappy about compiling with 2.13 code).

I tracked this down to the file caching done here - https://github.com/julianpeeters/sbt-avrohugger/blob/main/src/main/scala/sbtavrohugger/SbtAvrohugger.scala#L65

The files are cached when the first version finishes compiling and the other versions just don’t bother since the cache says it’s all good. I hope the fix is just using crossTarget instead (looks like it’s work locally) - https://github.com/julianpeeters/sbt-avrohugger/pull/88
