Note: Some input files use or override a deprecated API. ( It simply means that you are calling methods which have been marked with a  @Deprecated  annotation.) Note: Recompile with -Xlint:deprecation for details. (Probably, that is because you need to declare a List object, say (e.g.), without omitting '<' and '>': List < Integer > list = new ArrayList < Integer >();) Note: Some input files use unchecked or unsafe operations. ( for example when you call a function that returns Generic Collections and you don't specify the generic parameters yourself. for a function List < String > getNames () List names = obj . getNames (); will generate this error. To solve it you would just add the parameters List < String > names = obj . getNames ();) Note: Recompile with -Xlint:unchecked for details. ( From what I can tell in the docs, you can't do it on the command-line. According to the  javac  documentation , -Xlint:none only disable
