Compiled `.class` May Differ from Source Filename - map_deploy_to_devel (scala)

[chinyeungli]

In Scala, a compiled .class file may not directly correspond to its source filename. For example, Hello.scala can produce both Hello.class and World.class.

Use case

Project: pekko-cluster-sharding-typed

source: https://repo1.maven.org/maven2/org/apache/pekko/pekko-cluster-sharding-typed_3/1.2.0/pekko-cluster-sharding-typed_3-1.2.0-sources.jar
binary: https://repo1.maven.org/maven2/org/apache/pekko/pekko-cluster-sharding-typed_3/1.2.0/pekko-cluster-sharding-typed_3-1.2.0.jar

With filename mapping:
source

from/org/apache/pekko/cluster/sharding/typed/ClusterShardingQuery.scala

binary

to/org/apache/pekko/cluster/sharding/typed/ClusterShardingQuery.class
to/org/apache/pekko/cluster/sharding/typed/GetClusterShardingStats.class
to/org/apache/pekko/cluster/sharding/typed/GetShardRegionState.class

Only the to/org/apache/pekko/cluster/sharding/typed/ClusterShardingQuery.class are considered mapped.
GetClusterShardingStats.class and GetShardRegionState.class will be considered as "missing source".

However, if look into the ClusterShardingQuery.scala,

final case class GetShardRegionState(...)
.
.
.
final case class GetClusterShardingStats(...)

GetClusterShardingStats.class and GetShardRegionState.class are inner class and should be treated as compiled from ClusterShardingQuery.scala
