Hello,
I made up the following quick test and the 'outputproperty' of the <java> task
worked just fine
Stupid JAVA class to generate the 'new' password and write the value to
System.out (so that it can be captured into the 'outputproperty')
public class GeneratePassword {
public static void main(String[] args) {
System.out.println(args[0].toUpperCase());
}
}
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
I created the following property file to contain the current password text
value.properties:
my_password=Secret
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Here is the quick build.xml with the target
<project name="test" default="convert_password">
<property name="prop_file" value="value.properties"/>
<target name="convert_password">
<property file="${prop_file}"/>
<echo> Current value of my_password is ${my_password}</echo>
<java classname="GeneratePassword" outputproperty="new_password">
<arg value="${my_password}"/>
<classpath>
<pathelement path="."/>
</classpath>
</java>
<echo>New password is ${new_password}</echo>
<copy file="${prop_file}" tofile="new_${prop_file}"/>
<replace file="new_${prop_file}" token="${my_password}"
value="${new_password}"/>
<echo>The new password is stored in the file called new_${prop_file}</echo>
</target>
</project>
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
And here is the output:
C:\workspace\Test\bin>ant
Buildfile: build.xml
convert_password:
[echo] Current value of my_password is Secret
[echo] New password is SECRET
[echo] The new password is stored in the file called new_value.properties
BUILD SUCCESSFUL
Total time: 0 seconds
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
In my example I wrote the 'updated' password into a copy of the of the original
file...if you want to overwrite the original value just skip the <copy> task
and adjust the "file" attribute in the <replace> task to match the orginial
file name
Hope that helps....

Subject: How to make "outputproperty" element work???
Hi Friends,
I need some help with "outputproperty" element. I have a properties file, i
want to pass in one of the property to a java program and read the response
back and store it in the same property using ant for eg:
my_property=plain_password
//I want to pass this to a java program and the property should be modified
as:
my_property=encrypted_password
I tried to use "JAVA" task but redirection was not working so I used this
"exec" task instead:
<filter filtersfile="myfile.properties"/>
<target name="test">
<exec executable="${ext}" resolveexecutable="true" os="Windows XP">
<arg value="/c"/>
<arg value="call-program.${ext} ${my_property}"/>
<redirector output="myfile.properties"
outputproperty="my_password" append="true" />
</exec>
</target>
But its not working. I am able to redirect the output to some other file eg,
"xyz.txt" but then too the outputproperty element is not working,I want the
output as:
property=value
I have tried a lot, can somebody please give me a clue as to where i am
going wrong.I would really appreciate that.
Cheers
