Hello,
In my project developed using Vaadin 24.3.2 version and Spring Boot, I select the production profile and run prepare-install afterwards, then I run the package.json file with node.js and the node-modules folder is created. However, during mvn-install, I encounter the following error:
Cannot invoke “java.lang.Class.isInterface()” because the return value of “org.reflections.Reflections.forClass(String, java.lang.ClassLoader)” is null
Is there anyone who can help with this?
