DC Build Warning

Question

Hi,
When I build my DC I get the following warning

[wdminimize] ERROR: failed to parse public part file list
[wdminimize] ERROR: Non Fatal Error: failed to analyze public part definitions, minimizer skipped
[wdminimize] WARNING: Minimization skipped due to non fatal errors (see above). Classes have not been touched.
     [timer] Class minimizer finished in 0.130s
When I search for this file, I can see one thread in SDN but I am not authorized to the same since that thread is for SAP insiders only.
Please help.

Answer 1

What SP level are your NWDS, Web AS and JDI?
This looks like a Web Dynpro DC. In that case you can see if a Repair -> Project Structure and Classpath fixes the problem (you can do this from the context menu of your project in the Web Dynpro Explorer view).
If that doesn't fix the problem, try checking in your activity without activating, then Remove the DC from your client (using the Development Configurations perspective) and recreate the project. When lucky NWDS will recreate the file for you.
PS. Next time give a little bit more information (SP levels, DC type, etc.), so we can help you more quickly.
