Access to only one .aar file?

Hey guys I compiled a .aar file for sombody else to use for Android. The .aar file has 3 java files "in" it but their compiler only compiles a single file from that .aar file. We decompiled the .aar file to confirm that all 3 java files are compiled into the .aar file.Would anybody know how to compile the other files for the person using my .aar file?
