Including JARs and Class files

["Arpe, Kevin C" <Ke...@jpmorgan.com>]

Hi,

I am trying to launch Ant v1.8.1 on Windows using Java 1.6.0_24.

I have some JARs and class files that I need to reference from my build.xml.

I tried a few combinations of CLASSPATH (please don't throw stones!) and -lib arguments.  None of can do what I want 100%.

In my dreams:
ant.bat -lib "MyProject\lib" -lib "MyProject\bin" -file build.xml <args>

Inside "MyProject\lib" there are many JARs that I want to include.  I don't want to specify by name because sometimes the names change (when JAR versions change).
Inside "MyProject\bin" is a tree of class files.  Example: "MyProject\bin\net\sf\blah\blah\blah\ThisOrThat.class"

I also tried using CLASSPATH:
set CLASSPATH=MyProject\lib*;MyProject\bin

This also does not work.  For some reason, the * is not exploded to a list of JARs by the JVM.  I assume it would work like the -classpath arg for the JVM.

At the moment, I am using the worst case scenario: CLASSPATH with specific JAR files names.

Surely, I can do better, but I don't know how.  =(

Can you please advise?  I am sure I am very close(!)... but just one or two characters away.

Thanks in advance,
Arpe

Try  this

set CLASSPATH=MyProject\bin

ant.bat -lib "MyProject\lib"  -file build.xml <args>


If I remember correctly, the -lib parameter is used to only add jar files to the classpath. you can't use it to add class files to the classpath

java 6 supports using wildcards in the class path.

so you could also try
set CLASSPATH=MyProject\bin;MyProject\lib\*

ant.bat  -file build.xml <args>
