Setting CLASSPATH in ANT?

Hobbes

Ok I'm going to write a way around it, but I was just wondering how do you add a directory of uncompressed java files to the classpath?

So I have something like this...

 <classpath>
      <pathelement location="${jar}/dir1"/>  
      <pathelement location="${jar}/dir2"/>  
      <pathelement location="${jar}/dir3"/>   
    </classpath>

dir 1,2 and 3 are expanded jar files with the class files removed (only java files+resources).

For some reason it ignores the directories. Is this because there are no class files?

They're gonna have to be compiled if you want to use them in your classpath.
Why are you putting source files in there?

Hobbes

Sorry for the confusion. I wanted to create one jar at a time but it had to see a load of other jars (which I hadn't built yet) in order to compile.

I was thinking of dumping the lot into a directory and just compile the whole tree but the manifest method of generating jars I've found to be very buggy.

This is the answer (figured it out)

You would do something like this.

<!-- Compile only dir1 stuff -->
<javac srcdir="${jar}/dir1:${jar}/dir2:${jar}/dir3">
    <include name="package/dir1/**"/>
</javac>

This would treat the sources as to be referenced when compiling but the include statement will only tell it to compile the package relating to what you are currently compiling.

Still not great (as I have to know my package paths) but at least it works now.

Cool! Wasn't aware of that feature.

I think you could also call different buildfiles for each one.

While we're on the subject (kinda), if I have a compiled resource bundle in a JAR, can I extract it out of the jar (removing it from the JAR) and still have it recognised by the Java App?

Hmm.. Bit confusing here...

What I want to be able to do is debug the resourcebundle (by compiling new versions of it, and dropping it into the same folder as the original parent Jar, without having to rebuild the Jar each time?

Am I making any sense at all?!
Does the compiled resource bundle have to be in the original Jar in order to be referenced, or can I simply add it to the classpath?

Hobbes

afaik you have to add the base point of the path to the classpath, but I could be wrong.

So if your file goes into

com\whatever\mystuff

you would have to make that directory structure and point to the base directory in your classpath.

Btw Enygma, thanks now that I think of it I will probably create a build file for each jar and call them.

That sounds about right.
Thanks Hobbes.

I'll try it out and let you know.
