"The declared package '' does not match the expected package "AssignmentOne.java"" -Java -VS Code

Question

Why am I getting this error in VS Code?

Things I've tried:

I am attempting to only run the file, ScannerInputDemo.java, but VSCode is also attempting to run the other .java files in my /Intro To Java folder.

I've tried modifying my launch.json file to remove the configuration for the AssignmentOne.java file hoping that it wouldn't attempt to read that file

Specs: I'm using a Mac Book Pro 13", mid 2009.

My version check is:

openjdk version "11.0.7" 2020-04-14

Answer 1

I encountered the same issue.

Issue was in .classpath file, present in the project directory.

It contained

classpathentry kind="src" output="target/classes" path="src"

I updated it to

classpathentry kind="src" output="target/classes" path="src/main/java"

and it worked.
