Do you have the output from javac?
Without seeing the output, there are 2 possible things I can think of.
Firstly, are you sure that you're using version 6 of the JDK?
Secondly, your use of backslashes suggests that you are running on
Windows. I recently built ThreadWeaver on Windows, and I think I had
to put absolute paths into build.properties instead of relative ones:
cglib-jar=c:/java/lib/cglib-2.2.jar
If neither of these two things is the problem, I think I'd need to see
the output from javac to be able to help you.

Thanks for your prompt response.
Unfortunately, there's no javac output being produced. - which is half the
problem as I'm unable to debug. I can't see any compiler suppression flags
in the build.xml, so not quite sure what the problem there is. I've tried
forcing some other errors to prove that javac output can be produced, and
it's not some setting on my end.
using version 6.0.200.2
I've changed to absolute paths just incase but it doesn't seem to help.
I've added an echo in /main/build.xml to verify the parameters are being
passed correctly, which they seem to be.

I'll try to reproduce this. Can you confirm you're running on Windows, and
let me know which version? Also, are you launching ant from the command
line, or are you using an IDE? Which version of javassist are you building
against?
Thanks.

Thanks.
I'm attempting this build on Windows XP using Ant through eclipse.
I took the advice in the documentation and am using Javassist 3.8.1

Hi Iain,
I'm not sure I fully understand your workflow here. I've tried to import
ThreadWeaver into Eclipse, by using the 'Java Project from Existing Ant
Buildfile" option, but that doesn't work. (This is a limitation of Eclipse
- it can only handle certain kinds of build.xml files, and in general, this
feature is designed to parse build files that were autogenerated by
Eclipse.)
I can create a new Eclipse project from the ThreadWeaver source, and then
run the build.xml file successfully, but I can't actually build the project
directly using Eclipse until I manually import the various dependent jars
into the Eclipse build path.
This might be your best approach. Alternatively, I've attached an Ant built
file that was autogenerated by Eclipse after I'd configured it manually.
You'd need to set your own paths to the various dependent jars.
If you want to debug the original problem, can you try running ant from the
command line rather than from Eclipse? That might give you better
diagnostics.

I've now run it from command line, which returns the same error but at
least provides javac output. I get 100 javac errors for missing symbols -
which suggests it's not importing a library.
[javac]
pathToSource\main\com\google\testing\threadtester\TestInstrumenter.java:648:
cannot find symbol
[javac] symbol : class NotFoundException
[javac] location: class com.google.testing.threadtester.TestInstrumenter
[javac] } catch (NotFoundException e) {
[javac] ^
With regards to using eclipse; my workflow was to create a new project from
source and add the libraries manually to the classpath.
I've also exported eclipse to an Ant build file, which is copied below for
comparison:

The NotFoundException is a javassist class. Most likely there is something
wrong with your javassist jar file, or with the path to it. Can you please
verify that you have the correct name? In your build file yo are
referencing "lib/javassist.jar" Is that the actual name of the jar file, or
is there a version number as well? (E.g. javassist_3.8.4.jar, or something
like that.)
If the path is correct, please verify the jar. Go to the directory that
contains hte jar and run:
jar tf javassist.jar
Should get output like this:
META-INF/
META-INF/MANIFEST.MF
javassist/
javassist/ByteArrayClassPath.class
javassist/CannotCompileException.class
javassist/ClassClassPath.class
In particular, check for:
javassist/NotFoundException.class

Comment #8 on issue 6 by iainsproat: Refuses to build due to error running

NotFoundException is there:
> jar tf javassist.jar
....
javassist/LoaderClassPath.class
javassist/Modifier.class
javassist/NotFoundException.class
javassist/SerialVersionUID$1.class
javassist/SerialVersionUID$2.class
....
Would seem to be a problem with the path. I've attempted once again with
absolute paths, but no luck.

The only other thing I notice that's obviously different is the order of
the jars. I have javassist as the first jar. I suppose you might try to
change that and see what happens?
Alternatively, try building directly from Eclipse rather than from the ant
build file. Add all the source, add the external jars, and see if Eclipse
will build it for you.
As another suggestion, try building a simple app using javassist. I think
the javassist download comes with some. Or see
http://www.ibm.com/developerworks/java/library/j-dyn0916.html. Create a
separate project, and see if you can build that.
Sorry I can't be of further help, but it looks as though there must be
something odd with your build setup. I have built ThreadWeaver on Windows
with no problems.
