Incorrect Package Warning even with correct folder structure #905
Description
Incorrect Package error
Problem:
Even when my Java package names match the folder structure, VS Code shows an “Incorrect Package” error.
For example, my structure is:
src/
└── Model/
├── Doctor.java
├── Hello1.java
└── Tester.java
Inside Tester.java:
package Model;
public class Tester {
}
But VS Code highlights the package Model; line with:
Incorrect Package (hints: 1:9-1:14)
This error goes away only after restarting VS Code, but it keeps coming back when I open or create new files.
Steps to Reproduce:
Create a folder src/Model/
Add Tester.java with package Model;
VS Code shows "Incorrect Package" error even though structure is valid.
Expected Behavior:
The Java package should be recognized correctly without requiring a VS Code restart.
Actual Behavior:
Incorrect package warning is shown until I restart VS Code.

Hi Mithun Thomas (@mithun2003), I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.
src/Model, it treats the workspace root as the source folder and reports anypackagestatement as mismatched. To fix:pom.xmlorbuild.gradle) or a Eclipse.classpathfile in your project root so JDT LS auto-detectssrc.srcas a source path in your settings.json:src, notsrcitself, as your workspace root.Duplicate of:

Thanks for the quick reply. I’ve already tried the suggested steps:
My
settings.jsonalready contains:I am opening the project root (the folder containing src/, not src directly).
I also tried Java: Clean the Java language server workspace from the command palette, but the problem still persists.
The issue remains:
When I create or open a file inside src/Model/, VS Code shows Incorrect Package under package Model;.
The error disappears only after restarting VS Code, which suggests it’s not picking up source paths properly until restart.
So this doesn’t seem to be just a configuration issue, but possibly a bug in the Java Language Server’s handling of new files/folders without restart.

Mithun Thomas (@mithun2003) can you share the extension versions of your"Extension Pack for Java" and "Language Support for Java by Red hat"?
DonPalwo, do you see the exact the same error? Would you like to share your extension versions?
