The above error indicates that buildear is not able locate BW palettes which are required for building the ear file. 

This is a classpath issue. The buildear.tra depends on designer.tra so check the tibco.env.CUSTOM_CP_EXT contains the path to BW palettes. 

If you have another setup where Buildear utility is working fine, then you can compare the designer.tra / buildear.tra from working and non-working setup.
