I found the output of bitbake-laysers is stderr, not stdout, enven the output is not an error message.

Example:
##############
$ bitbake-layers show-layers > my.log
layer                 path                                      priority
==========================================================================
meta                  /buildarea/jenkins-yocto/poky/meta        5
meta-yocto            /buildarea/jenkins-yocto/poky/meta-yocto  5
meta-yocto-bsp        /buildarea/jenkins-yocto/poky/meta-yocto-bsp  5
##############

Then the my.log is empty. I must run the following command to redirect the output. 
#################
$bitbake-layers show-layers 2> my.log

$ cat my.log 
layer                 path                                      priority
