In Java how do I list all packages and classes available at run time? #765
-
|
I'm playing with reflection, writing a search form with suggest-auto-complete. Ultimately I'd like either a way to pull all packages and classes OR have a way to list all packages and classes immediately in the current package level (even at root level), the same way that when I start typing I tried to build a list of all packages and classes like this: public class ClassPathScanner {
public static Set<String> getVisiblePackagesAndClasses() {
Set<String> classNames = new HashSet<>();
try (ScanResult scanResult = new ClassGraph()
.enableAllInfo()
.acceptPackages("java", "javax", "com.marginallyclever") //, "com", "org", "jdk", "sun"
.scan()) {
classNames.addAll(scanResult.getAllClasses().getNames());
}
return classNames;
}
}It omitted all java.* packages. example, java.math and java.lang are not in the results (see end). What am I doing wrong? How do I get it right? My Maven Thank you! |

Before you scan, call
.enableSystemModulesAndPackages()or similar (I may have the name slightly wrong, this is off the top of my head).
