The errors I showed are from -debug. Without it it just says "IOException". Everything else looks reasonable.
Yes, ${javabin} is set. I get a different error if the file is not found.

I tried adding this chunk of code: <loadproperties srcfile="${javabin}/com/cleancode/data/Diagnostic.class"> <filterchain> <classconstants/> </filterchain> </loadproperties>
but received this error:
C:\usr\ms\devel\cleancode-support\build.xml:100: Unable to load file: java.io.IOException at org.apache.tools.ant.taskdefs.LoadProperties.execute(LoadPrope rties.java:225) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275) at org.apache.tools.ant.Task.perform(Task.java:364) at org.apache.tools.ant.Target.execute(Target.java:341) at org.apache.tools.ant.Target.performTasks(Target.java:369) at org.apache.tools.ant.Project.executeTarget(Project.java:1214) at org.apache.tools.ant.Project.executeTargets(Project.java:1062) . . . --- Nested Exception --- java.io.IOException at org.apache.tools.ant.filters.ClassConstants.read(ClassConstant s.java:136) at org.apache.tools.ant.filters.BaseFilterReader.read(BaseFilterR eader.java:86) at java.io.Reader.read(Reader.java:100) at org.apache.tools.ant.util.FileUtils.readFully(FileUtils.java:1126) at org.apache.tools.ant.filters.util.ChainReaderHelper.readFully( ChainReaderHelper.java:231) at org.apache.tools.ant.taskdefs.LoadProperties.execute(LoadPrope rties.java:202) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275) . . .
Any thoughts?
