[SOLVED] reflections.io Version 0.10.2 looking for a class works in IDE but not when running it as jar

reflections.io Version 0.10.2 looking for a class works in IDE but not when running it as jar

Old way of using Reflections doesnt find classes when run from commandline (java -jar myapp.jar) anymore, despite being documented as still supported:

var reflections = new Reflections("com.package", Scanners.TypesAnnotated, Scanners.SubTypes);
Set<Class<?>> restBaseEnablingClasses = reflections.getTypesAnnotatedWith(MyAnnotation.class);

Still works in IDE (Intellij and Eclipse) though...

What could be the reason?

Solution

This is a known bug and is documented here

In my case workaround offered there kept giving me java.lang.SecurityException: sealing violation because the BuiltinClassLoader and ClassLoader used by reflections.io library were loading jars twice - so I had to specify classloader when instantiating the Reflections class:

static Reflections reflections = new Reflections(
            new ConfigurationBuilder()
                    .setClassLoaders(new ClassLoader[]{
                            ClassLoader.getPlatformClassLoader()
                    })
                    .setUrls(ClasspathHelper.forPackage("com.package")
            )
        );
