Nested package declarations in Scala are highlighted as errors

[odisseus]

Scala allows multiple package declarations in the same file. In the following example, the full name of the class is going to be foo.bar.Baz:

package foo
package bar
class Baz {}

According to the Scala conventions, a file with this code should be located at foo/bar/Baz.scala. However, the Bazel plugin marks the package declarations as mismatched with the file path.

Here's a minimum example project that showcases the problem. example.zip

If it's any help the code for this is here:

https://github.com/bazelbuild/intellij/blob/e8fa25e29f338c6e089fccec8dfcfe50f3c37971/java/src/com/google/idea/blaze/java/sync/source/JavaSourcePackageReader.java#L66-L71

which is used used here:

https://github.com/bazelbuild/intellij/blob/f894c76e3f492cf9322a9142b43fc0cf2526b39f/java/src/com/google/idea/blaze/java/sync/source/SourceDirectoryCalculator.java#L102-L106

It's just grabbing the first line that looks like package ... and using that to infer the source roots.

Are multiple packages objects handled correctly with other build tools in Intelij, like SBT? I wonder if there is something missing in Bazel plugin in regards to Scala support, or is it an issue in Scala plugin.
