Building a MEEP project fails with the following error
Platform UEI-1.0.1 does not support "CLDC-8.0" configuration, setting back to CLDC-1.1.
C:\Users\shgovin.ORADEV\Documents\NetBeansProjects\MEEmbeddedProfileApplication2\nbproject\build-impl.xml:431:
java.io.IOException: Cannot run program "D:\ws\me8\trunk\sdk\release\JavaME8_SDK\bin\preverify" 

Starting from ME8, there will not be a need for preverification and hence the preverification tool (preverify) will not be part of the SDK. 

The ideal solution would be to skip the nb-preverify task from the build-impl.xml if the project uses CLDC 8.0 configuration. The temporary workaround is to simply copy the sources classes to the preverified output folder, so that the rest of the tool chain will function correctly.
