Hi Paul and Khem,
Thank you very much. I checked the BBPATH and BBFILES definition, found 
them are defined in 'overo-oe/build/profile' and 
'overo-oe/build/conf/site.conf' respectively. Originally, when I started 
the bitbake process, all of the recipes including my new test-recipe 
would be built once. by stripping away the suffix the test-recipe could 
be built successfully. The former experiment that includes suffix of .bb 
in the bitbake instruction just followed the instance of 'OpenEmbedded 
User Manual'.
Then I added the definition of BBFILES according to the absolute 
directory as BBFILES = 
“/lhome/zhonghua/overo-oe/org.openembedded.dev/recipes/*/*.bb” to the 
'overo-oe/build/conf/local.conf', found that in the bitbake process only 
what I designated recipe has been built but the question of "ERROR: 
Nothing PROVIDES '.....' also occurred. If I change the definition of 
BBFILES in the 'local.conf' to relative directory as 
BBFILES="${OEBRANCH}/recipes/*/*.bb ${USERBRANCH}/recipes/*/*.bb", the 
bitbake can succeed but again all recipes are built once. So could 
someone be so nice to tell me how can I control to just finish what my 
desired recipe?
