Strange problem with tag

Hi

I try to execute a batch file("foo.bat") from an Ant build script. The 
batch file executes a java application. 
The java application requires some additional libraries. The libraries are loaded over the java 

classpath option. Now I want specify the classpath using the Ant <arg> 
tag.

E.g.. 

<target name="foo">
        <exec executable="foo.bat">
            <arg line="-cp classes;lib/bar.jar"/>
        </exec>
</target>

foo.bat:

echo %1 %2 %3
rem java -cp 2% foo.Foo


The problem is that something goes wrong with the classpath.
In detail the semicolon between the lib files is missing.

E.g..

java -cp classes lib/bar.jar foo.Foo

in place of

java -cp classes;lib/bar.jar foo.Foo


Any suggestions or pointers would be greatly appreciated. 
Thanks in advance. ,

yes -some of the BAT handling in versions of windows split up semicolons.
There are workarounds for this in ants own handling of its command line
parameters.

Hi Montsie,
     Could ye maybe try putting the classes;lib/bar.jar in enclosed
escaped quotes? Maybe the ; is getting parsed out at some stage?

HTH,
Mark.


i.e.
<target name="foo">
        <exec executable="foo.bat">
            <arg line="-cp \"classes;lib/bar.jar\""/>
        </exec>
</target>
