Ant compilation problem [message #301072]

I have been trying (unsuccessfully) to get Eclipse Ant to run a
compilation using the Eclipse compiler. I have found '000 of entries on
this subject, but never one that works for me.
1) I have the jdtCompilerAdapter.jar in my Ant properties ClassPath. The
jar is found in:
C:\eclipse\configuration\org.eclipse.osgi\bundles\107\1\.cp\

2)the build file is similar to the one found in the Eclipse help files, as
follows:
<?xml version="1.0" encoding="UTF-8"?>
<project name="compile" default="main" basedir="../.">
<property name="build.compiler"
value="org.eclipse.jdt.core.JDTCompilerAdapter"/>
<property name="root" value="${basedir}"/>
<property name="destdir" value="bin" />
<target name="main">
<javac srcdir="." destdir="bin" classpath="${classpath}"
debug="off"/></target>
</project>

I receive the following error:

[javac] Compiling 38 source files to C:\eclipse\workspace\testproject\bin

BUILD FAILED
java.lang.NoClassDefFoundError:
org/eclipse/jdt/internal/compiler/impl/CompilerOptions

Any suggestions?
Many thanks

Are you running the build in the same or separate JRE from Eclipse?
To keep it simple, try running in the same JRE.
See the JRE tab for your Ant launch configuration for the Ant build.

Thanks Darin for your prompt help, changing the setting for the JRE got
the compiler running, but I now receive '00s of compiler error messages
which I don't get when I compile in Eclipse. I think my external jars
required for compilation are not being found, but the classpath property
is set in my build file.
Any other good suggestions. You are doing well so far...

Darin, please ignore my previous message. Your earlier one in fact
resolved the problem completely. I found that the reason why the libraries
were not found was entirely correct, a previous attempt at getting the
build file to run with a clean compile had deleted all the libraries! I
apologise for involving you in my mishap.
All is well now.
Many thanks
