Possible problem with Vaadin 24.4.1 and Popup 24.0.5
vadin:prepare-frontend now fails with:
[ERROR] Failed to execute goal com.vaadin:vaadin-maven-plugin:24.4.1:prepare-frontend (default) on project ptsmc-widgetset: Could not execute prepare-frontend goal.: Error occured during goal execution: Cannot invoke “java.lang.Class.isInterface()” because the return value of “org.reflections.Reflections.forClass(String, java.lang.ClassLoader[])” is null
Building with --debug I get
[DEBUG] Can’t load class com.vaadin.componentfactory.Popup java.lang.NoClassDefFoundError: com/vaadin/flow/component/shared/HasThemeVariant at java.lang.ClassLoader.defineClass1 (Native Method) at java.lang.ClassLoader.defineClass (ClassLoader.java:1012)
Same Popup version worked fine with Vaadin 24.3.12, so not sure what to make of it
