/** Returns a custom ConsoleAppender that will skip log messages starting with a certain prefix.

|
|
* coming from the analyzing compiler (wrapper around java compiler) when it tries to match class files
|
|
* to source files. There is absolutely no way to tell SBT that that some sources are being generated from
|
|
* annotation processors and it will get them during the same compilation round. Nor can we easily
|
|
* suppress such warning.
