Getting java.lang.ClassNotFoundException: jakarta.servlet.ServletContext [duplicate]

Question

I installed Intellij on my new laptop and I attempted to run a very simple Spring Boot web app from a course i cloned. When I run the app, I keep getting the same java.lang.IllegalStateException: Failed to introspect Class [org.springframework.web.context.support.GenericWebApplicationContext] from ClassLoader [jdk.internal.loader.ClassLoaders$AppClassLoader@2f0e140b] followed by java.lang.ClassNotFoundException: jakarta.servlet.ServletContext. Everything works fine when i run the app in (for example) Visual Studio Code.

My pom.xml file:

I tried downloading multiple versions of jakarta.servlet-api and I get the same error every time. When I download jakarta.servlet-api, I don't get ServletContext interface in jakarta/servlet folder. Is there something I'm missing?

Here is the full stack trace:

Try adding <scope>provided</scope> in your jakarta servlet dependency like below: — jarvo69

<dependency> <groupId>jakarta.servlet</groupId> <artifactId>jakarta.servlet-api</artifactId> <version>version</version> <scope>provided</scope> </dependency> — jarvo69

Your POM says Spring 6 & Spring Boot 3, but your error message says you are using Spring 5 and Spring Boot 2. — Basil Bourque

Your pom looks good. Try the suggestion from this post: Force Intellij IDEA to reread all maven dependencies. From what I can tell your intelij is has not loaded the dependency into your env yet.
