Sorry that's not completely right...
I mean
<javac srcdir = "/shared/projects/generated:/shared/projects/src/java" .../>

Unfortunately, you are compiling a static final String :(
Perhaps a properties file distributed with your app could hold the
String instead?
I wasn't proposing copying, replacing and then copying back... What I
meant was this:
I assume your source code is checked into some source control systems
like Subversion or CVS? Therefore, you probably want to copy the file
elsewhere solely for the purpose of doing the text replacement...
Otherwise, the file will show it is in a modified state (for example
running "svn stat")...
You can copy the file to a new location and add that dir as part of
the Java source path in the javac task... It will pick up the copied
file over the other non-modified one... Of course, you want to keep
the directory structure the same where you copy it over... For
example lets say your source is in
/shared/projects/src/java/com/Main.java, you might want to copy to
/shared/projects/generated/com/Main.java and then do this:
<javac srcdir = "/shared/projects/src/java:/shared/projects/generated"
.../>
Does that make sense?

Thanks for the reply and a possible solution but this seems more like a
hack.
Yeah, right now I have something like
Public static final String programName = "Java Program XYZ";
I'd like to be able to make one where that string is "Java Program XYZ -
Development Version" automagically using ant.
If the javac command could set properties the way the java command does
it would be nice.
If this isn't the case I guess I'll be stuck with a "hack" like this.
Just seems to be a pain to explicitly copy the original to a tmp
directory, do the replacement on the file, compile it and then copy the
original file back.

Eric:
You mention "final Java Strings at compile time"...
Are you referring to actual Java as in:
public static final String FOO = "some text";
If so, you may want to look into the <replace> task...
You could do something as simple as:
public class Main
{
public static final String FOO = "%PROJECT NAME%";
...
}
<replace file = "Main.java" token = "%PROJECT NAME%" value = "Some
Value"/>
Of course, you probably want to copy off Main.java to a new dir and
do the replacement there - compiling that copied version of course...

Hello,
Is there an easy way to set final Java Strings at compile time?
I know you can set properties at runtime with
-Dproperty=value but could
I do this at compile time?
What I want to do is have one target which makes a program
called "Java
Program XYZ - production" and another which is called "Java
Program XYZ
- development".
Also, it would be useful to somehow get the date and time
at which it
was compiled into the program.
I figured this would be common, hopefully it is. Perhaps I
just don't
know the right words to search on Google.
Thanks in advance,
