Showing an error with scala protobuf generation If you run

sbt compile

You will get the following error:

[error] /Users/xxx/test/protobuf_scala_test/target/src_managed/main/compiled_protobuf/test/ContentCategory.scala:11: method isIab11 is defined twice
[error]   conflicting symbols both originated in file '/Users/xxx/protobuf_scala_test/target/src_managed/main/compiled_protobuf/test/ContentCategory.scala'
[error]   def isIab11: Boolean = false
[error]       ^
[error] one error found
[error] (compile:compileIncremental) Compilation failed

Because the scala it generates is like so:

package test
