Class GroupTree

java.lang.Object

org.eclipse.aether.internal.impl.filter.ruletree.GroupTree

public class GroupTree
extends Object

Group tree for Maven groupIDs. This class parses a text file that has a directive on each line. Directive examples:

• ignored/formatting - each line starting with '#' (hash) or being empty/blank is ignored.
• modifier ! is negation (disallow; by def entry allows). If present must be first character.
• modifier = is limiter (to given G; by def is "G and below"). If present, must be first character. If negation present, must be second character.
• a valid Maven groupID ie "org.apache.maven".

By default, a G entry ie org.apache.maven means "allow org.apache.maven G and all Gs below (so org.apache.maven.plugins etc. are all allowed). Examples:

# this is my group filter list

org.apache.maven
!=org.apache.maven.foo
!org.apache.maven.indexer
=org.apache.bar

File meaning: "allow all org.apache.maven and below", "disallow org.apache.maven.foo groupId ONLY" (hence org.apache.maven.foo.bar is allowed due first line), "disallow org.apache.maven.indexer and below" and "allow org.apache.bar groupID ONLY".

In case of conflicting rules, parsing happens by "first wins", so line closer to first line in file "wins", and conflicting line is ignored.
