question: private String checkDependencies ( ModuleDescriptor md , HashMap < String , ModuleDescriptor > modlist ) { logger . debug ( "Checking dependencies of " + md . getId ( ) ) ; ModuleInterface [ ] requires = md . getRequires ( ) ; if ( requires != null ) { for ( ModuleInterface req : requires ) { String res = checkOneDependency ( md , req , modlist ) ; if ( ! res . isEmpty ( ) ) { return res ; } } } return "" ; }
target:  Check that the dependencies are satisfied.
