TrackingFileManager
@Singleton @Named public final class DefaultTrackingFileManager extends java.lang.Object implements TrackingFileManager
Manages access to a properties file.Note: the file locking in this component (that predates
SyncContext
) is present only to back off two parallel implementations that coexist in Maven (this class andmaven-compat
one), as in certain cases the two implementations may collide on properties files. This locking must remain in place for as long asmaven-compat
code exists.
