Question

I’m having issues in trying to iterate values defined in a property file. I’m trying to read jar files in a loop and copy them to a directory. The jar file names are defined in a property file. Here’s my sample file :

<?xml version="1.0"?><project name="beehive" basedir=".">

<taskdef resource="net/sf/antcontrib/antlib.xml"/>

<loadfile property="file.list" srcFile="test.txt">
    <!--<filterchain>
        <striplinebreaks/>
    </filterchain>-->
</loadfile>

<target name="testtarget">
    <for list="${file.list}" param="fileName">
        <sequential>
            <echo>@{fileName}</echo>
            <copy file="C:/Development/Doc/Build/@{fileName}" todir="C:/Development/Doc/Build/testdir">
            </copy>
        </sequential>
    </for>
</target>

Here’s the entry in test.txt.

wikihelp-1.0.0.jar

velocity-1.0.0.jar

I’m expecting that the for loop will read file name one at a time then perform the copy. Instead,its reading the 2 file names together and throwing the following exception :

Warning: Could not find file C:\Development\Doc\Build\wikihelp-1.0.0.jar velocity-1.0.0.jar to copy.

Any pointers will be appreciated.

Found the issue, adding delimiter=”${line.separator} resolved it

In the for loop, I needed to add the delimeter for line seperator

<for list="${file.list}" param="fileName" delimiter="${line.separator}">
