I have a requirement using ant, that the target should extract the two parameters passed as comma separated in a long list of similar pair of parameters passed which are semicolon separated. Currently I am doing something like this:
<?xml version="1.0"?>
<project name="" basedir="." default="test" xmlns:ac="antlib:net.sf.antcontrib">
<target name="test" >
<echo message="Hey There I am using What's App" />
<ac:for list="asdfg,dasfdf;vxxexqxx,hyyypyly;dksfgsgdgf,abaifuacu" delimiter=";" param="val">
<ac:sequential>
<ac:propertyregex property="param1"
input="@{val}"
regexp="([^\.]*)\,.*"
select="\1"
casesensitive="true" />
<ac:propertyregex property="param2"
input="@{val}"
regexp=".*,([^\.]*)"
select="\1"
casesensitive="true" />
<echo message = "val = ${param1}"/>
<echo message = "value = ${param2}"/>
</ac:sequential>
</ac:for>
</target>
</project>
But I am getting the output as:
Buildfile: /tmp/Manish/build.xml
test:
[echo] Hey There I am using What's App
[echo] val = asdfg
[echo] value = dasfdf
[echo] val = asdfg
[echo] value = dasfdf
[echo] val = asdfg
[echo] value = dasfdf
So this is getting looped 3 times(correct) but by only the first value passed in the for loop parameter. Is there some obvious mistake I am making?
Thanks, Manish Joshi
Properties in Ant are immutable. You will need to use the variable task from ant-contrib (although it is discouraged) to unset the properties:
<ac:for list="asdfg,dasfdf;vxxexqxx,hyyypyly;dksfgsgdgf,abaifuacu" delimiter=";" param="val">
<ac:sequential>
<ac:propertyregex property="param1"
input="@{val}"
regexp="([^\.]*)\,.*"
select="\1"
casesensitive="true" />
<ac:propertyregex property="param2"
input="@{val}"
regexp=".*,([^\.]*)"
select="\1"
casesensitive="true" />
<echo message = "val = ${param1}"/>
<echo message = "value = ${param2}"/>
<ac:var name="param1" unset="true"/>
<ac:var name="param2" unset="true"/>
</ac:sequential>
</ac:for>
