Keep in mind that the execution of the Ant scripts and the
compilation are
two separate things, which means they are using two different
classpaths.
If
the compilation task is complaining about a missing class, then this
means
the class is missing from the classpath of the compiler, not the
classpath
of the executing Ant. You'll need the Eclipse compiler JAR on Ant's
execution classpath to execute the javac task.
This can be confusing when using the Eclipse compiler, since it doesn't
have
any "default" classpath. Normally when you're using 'javac' from a JDK,
the
classpath of the underlying JRE (all of the java.*, etc classes) is
automatically on the classpath. The Eclipse compiler is not part of a
JDK,
so there is nothing on the classpath by default.
