Thanks David,
Unfortunately I have no control over the contents of the file I'm parsing, and
I don't want to insert place holders.
I located the code that introduces this "feature" and have changed it locally
to work as I need it, but I would appreciate some feedback on what it might
break (if anything). It obviously does this for some reason, though there are
no hints in the code.
Modified code from 1.7.1 tag in svn:
org.apache.tools.ant.PropertyHelper.parsePropertyStringDefault(String, Vector,
Vector)
...
if (value.charAt(pos + 1) == '$') {
//backwards compatibility two $ map to one mode
fragments.addElement("$");
// MY CHANGE: Don't jump over double dollars.
// prev = pos + 2;
prev = pos + 1;
...
Regards,
Chris Holman

Interestingly, I ran the following test:
<project>
<property name="test1" value='$ $$ $$$ $$$$ $$$$$ $$$$$$'/> <!--
Try single quotes -->
<echo message="TEST #1 = ${test1}/> <!-- Prints $ $ $$ $$ $$$ $$$-->
<condition property="test2" value="test2 matches">
<equals arg1="${test1}" value="$ $$ $$$ $$$$ $$$$$ $$$$$$$"/>
</condition>
<echo message="TEST #2: ${test2}"/> <!-- Prints "TEST #2: test2 matches-->
<condition property="test3" value="test3 matches">
<equals arg1="${test1}" value="$ $ $$ $$ $$$ $$$"/>
</condition>
<echo message="TEST #3: ${test3}"/> <!-- Prints "TEST #3: ${test3}-->
</project>
So, the value of the variable seems correct, but the echo is wrong.
However, this does work:
<project>
<property name="dlr" value='$'/>
<property name="test1" value="${dlr} ${dlr}${dlr}
${dlr}${dlr}${dlr} ${dlr}${dlr}${dlr}${dlr}
${dlr}${dlr}${dlr}${dlr}${dlr} ${dlr}${dlr}${dlr}${dlr}${dlr}${dlr}"/>
<!-- Try single quotes -->
<echo message="TEST #1 = ${test1}/> <!-- Prints $ $$ $$$ $$$$
$$$$$ $$$$$$-->
<condition property="test2" value="test2 matches">
<equals arg1="${test1}" value="$ $$ $$$ $$$$ $$$$$ $$$$$$$"/>
</condition>
<echo message="TEST #2: ${test2}"/> <!-- Prints "TEST #2: test2 matches-->
<condition property="test3" value="test3 matches">
<equals arg1="${test1}" value="$ $ $$ $$ $$$ $$$"/>
</condition>
<echo message="TEST #3: ${test3}"/> <!-- Prints "TEST #3: ${test3}-->
</project>
So, by declaring a variable equal to "$" and using that instead of
dollar signs seems to work.
