java.lang.IncompatibleClassChangeError

[Former Member]

Hi All,

I goto Change Management Service and try importing SCA files into Development system. Import fails. I goto the log file and see java.lang.IncompatibleClassChangeError.

Any inputs ?

Following is the detailed error:

Hi Tom,

First try to import the dependencies like JTECHs,JBUILD,e.t.c.. after that try to import the main SCA files. hope this is the only problem. if any chnace try to work it out on new track so that conflict issues may not arise.

Regards,

Anil.

Hi Anil,

When I import dependencies I get java.lang.IncompatibleClassChangeError, but when I import the SCA files I get TCSCommunicationException error. I tried importing dependencies before, but still the same error.

Thanks,

Tom

Hi Tom,

Please check whether all the SCA files are in sync or not. check the patch levels and version nos also.

Anil.
