All Implemented Interfaces:

Cloneable

public class GetVersionPref
extends org.apache.tools.ant.Task

Implementation of the ant task . This ant task takes an input version string (e.g. 0.17.2) and set an ant property (whose name is specified in the property attribute) with the version prefix. For 0.17.2, the version prefix is 0.17. Similarly, for 0.18.0, the version prefix is 0.18. The version prefix is the first two components of the version string.

Field Summary

protected String	input The input string that contains the version string.
protected String	property The name of the property that gets the version prefix.

Method Detail

setProperty

public void setProperty(String property)

getProperty

public String getProperty()

setInput

public void setInput(String input)

getInput

public String getInput()

execute

public void execute()
             throws org.apache.tools.ant.BuildException

Executes the ant task . It extracts the version prefix using regular expressions on the version string. It then sets the property in the project with the extracted prefix. The property is set to an empty string in case no match is found for the prefix regular expression (which will happen in case the version string does not conform to the version format).

Overrides:

execute in class org.apache.tools.ant.Task

Throws:

org.apache.tools.ant.BuildException
