| Retrieve property value dynamically? | Retrieve property value dynamically? 2003-03-21 - By JONES, MARSHALL, ALABS
All,
Can the following be accomplished using properties? I have tried several
ways to do this, but have been unsuccessful. Maybe there is a good reason this
is not allowed? Or maybe someone can suggest an alternative solution.
I would like to retrieve the value of a property using a dynamic name
rather than hard-coding the name in my buildfile. I am doing this because I do
not know the range of possible property values until runtime.
Given a property file named "build.properties" with the following data.
allbuilds 0,1,2
build.0.date 20030319
build.1.date 20030320
build.2.date 20030321
I need to extract the date of a particular build once the user picks a build
number to install. The following code is an example of what I need to do:
<property file="build.properties"/>
<input validargs="${allbuilds}" addproperty="buildnumber" message="Enter
build number to install."/>
<property name="builddate" value="${build.${buildnumber}.date}}"/>
The result should be builddate getting the value of "20030320". Any assistance
or ideas would be greatly appreciated.
