Would it be better to use '_' instead of '$' to replace the '.' in the class name? That's definitely an option. Doing this automatically may then cause a clash with a class that uses _ already. There is a --rename flag that lets you control the name to pick: --rename 'full.package.path.here.SensitivityProfileIdList$Builder=SensitivityProfileIdList_Builder' (you need '' around a string with literal $ in a shell command line) Andi..

Hi Andi, I think I got it working but there is an issue with the class name with '.'. In the jar there are some class name like below public static final class SensitivityProfileIdList.Builder public static final class SRMBreakdown.Builder So JCC will wrap this can change the '.' to '$' SensitivityProfileIdList$Builder SRMBreakdown$Builder I cannot really use this classes in python and python flag it up as syntax error. Would it be better to use '_' instead of '$' to replace the '.' in the class name?
