Package org.eclipse.aether.internal.impl

Class DefaultTrackingFileManager

java.lang.Object

org.eclipse.aether.internal.impl.DefaultTrackingFileManager

All Implemented Interfaces:

TrackingFileManager

@Singleton
@Named
public final class DefaultTrackingFileManager
extends 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 and maven-compat one), as in certain cases the two implementations may collide on properties files. This locking must remain in place for as long as maven-compat code exists. IMPORTANT: This class is kept fully in sync with the master branch one (w/ simple change to convert File to Path instances).
