 Maven Plugin Utils is a Java library which contains utilities for [Maven 2](https://maven.apache.org/) plugins. It contains tools to:
-* scan directories for files and create a virtual (not physical) destination file in the output directory based on the source (see [biz.gabrys.maven.plugin.util.io](http://maven-plugin-utils.projects.gabrys.biz/1.4.0/apidocs/index.html?biz/gabrys/maven/plugin/util/io/package-summary.html) package)
-* log Mojos parameters (see [biz.gabrys.maven.plugin.util.parameter](http://maven-plugin-utils.projects.gabrys.biz/1.4.0/apidocs/index.html?biz/gabrys/maven/plugin/util/parameter/package-summary.html) package)
-* manage classpath (see [biz.gabrys.maven.plugin.util.classpath](http://maven-plugin-utils.projects.gabrys.biz/1.4.0/apidocs/index.html?biz/gabrys/maven/plugin/util/classpath/package-summary.html) package)
-* count execution time (see [biz.gabrys.maven.plugin.util.timer](http://maven-plugin-utils.projects.gabrys.biz/1.4.0/apidocs/index.html?biz/gabrys/maven/plugin/util/timer/package-summary.html) package)
