Re: Using ant properties in file -- Success

[Ninju Bohra <ni...@yahoo.com>]

The reason that I can't use
@@path_to_main_properties@@=@@deploy_dir@@\main.properties

is the same reason that my original approach wouldn't
work... the <replace> task does not examine/process
the contents of the filterFile.

But going off of what you alluded to, I did come up
with a two-pass approach...

My filterFile looks like:
# Properties to be replaced in the \WEB-INF\web.xml
file
@@path_to_ws_prop@@=${deploy.dir}/WSProp.xml
# Properties to replaced in the smokeTest.xml file
@@compare_output_dir@@=c:/ccbuild/workarea/${project.name}/integration_tests

First, I copy the filterFile (called
replacements.properties in my case) to temp file
(called adjusted_replacements.properties

Then I executed a series of simple replacements in the
adjusted_replacements.properties file, like:
   <replace file="adjusted_replacements.properties"
token="$${deploy.dir}" value="${deploy.dir}"/>
   <replace file="adjusted_replacements.properties"
token="$${project.name}" value="${project.name}"/>

Note the double $$'s in the "token" property -- to
prevent evaluation of the ${property}

And voila! the ${deploy.dir} in the
replacements.properties has been changed to
c:/Projects/MyDeployDir in the
adjusted_replacements.properties file

I then used the adjusted_replacements.properties as
the replaceFilterFile and do <replace>'s on the final
file.

It would have been nice if the <replace> task
supported the ability to pre-process the
replaceFilterFile, but oh well...

Thanx,

Ninju
