Examples of org.apache.maven.it.util.cli.Commandline

org.apache.maven.it.util.cli.Commandline

Commandline objects help handling command lines specifying processes to execute.

The class can be used to define a command line as nested elements or as a helper to define a command line by an application.

<someelement> <acommandline executable="/executable/to/run"> <argument value="argument 1" /> <argument line="argument_1 argument_2 argument_3" /> <argument value="argument 4" /> </acommandline> </someelement>

The element someelement must provide a method createAcommandline which returns an instance of this class.
