compress files to rpm using rpmbuild has error

[mohtay123456]

I download this Package util-linux-2.23.2-65.el7_9.1.src.rpm and extract it

rpm2cpio ./util-linux-2.23.2-65.el7_9.1.src.rpm | cpio -idmv
Among the files used there is a file named util-linux-2.23.2.tar.xz

I have extract this file and Editing one of the files login.c

Then I compressed the files once using the command

tar -cJvf util-linux-2.23.2.tar.xz util-linux-2.23.2/
Now when I try to compress files to rpm file I have this with the command

rpmbuild -ba ~/rpmbuild/SOURCES/util-linux.spec

I have this error:
