Ant and property files: get rid of commas in integers

Question

I have a property defined in one of my property files:

<entry key="build" default="0" type="int" operation="+" value="1" />

I read this property using:

<replacefilter token="@build@" property="build_num" />

Once this number gets bigger than 999, the thousands are separated from the rest of the digits by a comma, like this:

1,001

1,562

Is there a way to get rid of that comma? (I use build to generate a file name, and don't really want to see any commas in there).

Answer 1

http://ant-contrib.sourceforge.net/tasks/tasks/propertyregex.html

this ant task should do the trick

Answer 2

You can prevent thousand separators from being used by adding a pattern to the entry:

<entry key="build" default="0" type="int" operation="+" value="1" pattern="0" />

Note that you'll probably need to manually remove the commas one-time before running this - else your build numbers will reset, with the comma and subsequent digits being discarded. (So 1,325 -> 2 and 4,111 -> 5 and so on.)
