Are you attempting to build with CLI 4.1.2 or CLI 5.1.1?

[mohammad_javad_a_]

 build  CLI 5.1.1

[PaulF_IntelCorp]

Are you specifying some icons or splash screens using JPG images? If so, convert those images to PNG images, the JPG images don't work with Cordova CLI 5 build systems.

[Pamela_H_Intel]

As Paul says, you need to convert your images to PNGs, but also, your image name might have some characters that are not being translated correctly. You may need to change the filename.
