Hi,

I'm using Ant 1.7. I'm trying to de-hardcode a few things from my script, and would prefer to have them properties-file driven. However, I'm not sure how to go about it. I have



I would like to move the hosts and ports into a properties file and then load them into this task dynamically. Any ideas how to do this?

Thanks, - Dave

Something like

<property file="${user.home}/build.properties" />

would do the trick for settings that apply to all your projects. If it's just for one project you can keep the properties in the project folder:

<property file="build.properties" />

Thanks ... I actually know how to include a properties file, but what I'm asking is how would I take a property like this ...



and turn it into part of my target ...



? The tricky part is the fact that there could be an arbitrary number of comma separated hosts in the properties file.

The only way I know isn't quite as simple as a properties file.

I manually wrote a .json file, then created a class that reads in the JSON using a BufferedReader. A stringBuilder takes the input from the file, then I make a JSONObejct out of it (using the net.sf.json.JSONObject package). Then, store these values into a map that contains another class that I wrote that actually hold the values. It takes a little bit of effort but ends up working quite well.

I'm just curious on the next step. Once the required object is available, how do we access that object in ant file. Is there any library that can be used here?

Try using the antcontrib (http://ant-contrib.sourceforge.net/). It has a <for> and a <foreach> task.
 
Don't get me started about those stupid light bulbs.
