Using google reflections to load resource files

Question

I am working on a JavaFX project and I my project structure is as follows.

This is my Image

I want to load *fxml files under /src/main/java/resources/view/primary in /src/main/java/windchimes.ui/WindChimesApplication.java using Google Refletions. I tried using following code for it

Reflections reflections = new Reflections("windchimes.ui",new ResourcesScanner());
Set<String> scenePaths = reflections.getResources(Pattern.compile(".*fxml"));

When I run the above code snippet, java throws the following exception

Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:422) at com.sun.javafx.application.LauncherImpl.lambda$launchApplication1$161(LauncherImpl.java:819) at com.sun.javafx.application.PlatformImpl.lambda$runAndWait$175(PlatformImpl.java:326) at com.sun.javafx.application.PlatformImpl.lambda$null$173(PlatformImpl.java:295) at java.security.AccessController.doPrivileged(Native Method) at com.sun.javafx.application.PlatformImpl.lambda$runLater$174(PlatformImpl.java:294) at com.sun.glass.ui.InvokeLaterDispatcher$Future.run(InvokeLaterDispatcher.java:95) Caused by: java.lang.NoSuchMethodError: com.google.common.cache.CacheBuilder.maximumSize(I)Lcom/google/common/cache/CacheBuilder; at org.reflections.adapters.JavassistAdapter.(JavassistAdapter.java:28) at org.reflections.util.ConfigurationBuilder.(ConfigurationBuilder.java:41) at org.reflections.Reflections$1.(Reflections.java:134) at org.reflections.Reflections.(Reflections.java:134) at org.reflections.Reflections.(Reflections.java:117) at windchimes.ui.WindChimesApplication.(WindChimesApplication.java:27) ... 10 more

I am sure that I am not creating the Reflection object according to my use case. Can someone help me out ?

Answer 1

You need to specify the package prefix and also I believe you are looking for .fxml files. This code should work. Can you try it out?

    Reflections reflections = new Reflections(new ConfigurationBuilder().setScanners(new ResourcesScanner())
            .setUrls(ClasspathHelper.forPackage("windchimes.ui")));
    Set<String> res = reflections.getResources(Pattern.compile(".*\\.fxml"));
