vs code - Expected java package name error

Question

I have a java project with the following directory structure (as required by Gradle's 'java' plugin, assuming all defaults).

projectRootDir
 - src/main/java/com/myproj/Sample.java
 - build.gradle

And

// Sample.java code
package com.myproj;

public class Sample{
    ...
}

Opening projectRootDir folder in VS Code shows the following package naming error in Sample.java:

The declared package "com.myproj" doesn't match the expected package "main.java.com.myproj"

How to make VS Code recognise/use the package mentioned in the code?

Note: I am using the following extensions: Language Support for Java(TM) by RedHat and Debugger for Java by Microsoft.

Answer 1

If your files are already in the correct directory, press F1 and type in "Clean the Java Language Server Workspace"

Answer 2

Project Root --> .vscode --> settings.json

changed below entry to point to my root source folder. This was set to src/pkg1. Changed to src and it started working.

{ "java.project.sourcePaths": [ "src" ] }

Answer 3

Because vscode set the src folder as the default Java Source Path, you should change it to folder src/main/java. Just right click the folder src/main/java in vscode and click the option Add Folder to Java Source Path, then reopen the file, and the error is gone.
