Error Message : org.eclipse.jdt.core_2.0.2 . jdtCompilerAdapter can't be found.

[Tony Evans]

I am running ant within WebSphere5, when I use ant to run my build file I get the following Error:
Build exception:
C:\WSAD50Trial_Install\IBM\wsad\workspace\FirstJavaProject\build.xml:23:
org.eclipse.jdt.core_2.0.2.jdtCompilerAdapter can't be found.
But within my build.xml file I have added as a property the line.
<property name="build.compiler" value="org.eclipse.jdt.core_2.0.2.jdtCompilerAdapter"/>
The jdtCompilerAdapter resides in the following directory
C:\IBM\WebSpere studio\eclipse\plugins\org.eclipse.jdt.core_2.0.2.
my buildfile resides in the directory
C:\WSAD50Trial_Install\IBM\wsad\workspace\FirstJavaProject\build.xml
I ran the build file again with
<!--property name="build.compiler" value="org.eclipse.jdt.core_2.0.2.jdtCompilerAdapter"/-->
commented out.
And -Dbuild.compiler=org.eclipse.jdt.core_2.0.2.jdtCompilerAdapter passed in as an argument.
I got the same error message again.
Build exception: C:\WSAD50Trial_Install\IBM\wsad\workspace\FirstJavaProject\build.xml:23:
org.eclipse.jdt.core_2.0.2.jdtCompilerAdapter can't be found.
I am using WebSpere 5 with ant built in.
Cheers For any Help Tony
