I don't have the exact error message, but the situation was this: one of
our programmers likes to code everything with generics. The compile
problem in question involved a class using generics with an internal
class also using generics (i.e.
Public class foo <Source, Output>
{
Static public class fooNode <SourceType, OutputType>
{
Blah blah...
}
}
So the compiler spits out a foo.class and foo$fooNode.class.
When ant tries to compile the junit test for the class using javac,
using the class files generated by eclipse, it throws a javac error
referencing foo$fooNode.class saying that there's no definition for
"Source" (which the subclass doesn't reference) and that
foo$fooNode.class is a "bad class file" so the junit test can't compile.
When I delete all the .class files made by eclipse and have ant
build them all, I don't get the error.
Thanks

If you have the exact error message I would search the javac and Eclipse
bug database and see if it is a known problem (with potential
workaround)

RE: ant and eclipse?
I found the Java Compiler section of the Properties dialog, but as I say
it doesn't help clarify why the .class files it produces are
incompatible with the jdk javac ones.
Our eclipse project has
Compiler compliance level: 5.0
Use default compliance settings
Classfile generation:
Add variable attributes to generated class files
Add line number attributes to generated classfiles
Add source file name to generated class file
Preserve unused local variables
Our ant <javac> task ends up using
Jdk1.5.0_06\javac -deprecation -d <output path> -g *.java
As I say, the net result is that the eclipse .class files won't work
with the javac ones but I'm at a loss to figure out which options are
creating the incompatibility.
Thanks

Each Java Project in Eclipse has a JVM assigned to the project. If you
right-click the project name and select properties you can find it in
there.
