A collection of various utility classes to ease working with strings, files, command lines and more.
Starting with version 4, XML classes (in org.codehaus.plexus.util.xml and org.codehaus.plexus.util.xml.pull) have been extracted to a separate plexus-xml library: if you need them, just use this new artifact.
plexus-utils 4 keeps an optional dependency on plexus-xml 3 to keep compatibility with the few XML-oriented methods of ReaderFactory and WriterFactory: these classes are deprecated, you should migrate as explained in javadoc. And keep plexus-xml to 3 if you want Maven 3 compatibility, as plexus-xml 4 works only in Maven 4..
