Package Does Not Exist Error; Project builds and Runs OK.

Building a simple HelloWorld app to test importing an external .JAR file
The Jar was built with an earlier version of the JDK but builds on the command line without issues.
The linter indicates that the import class "Media" does not exist even though the jar file has been referenced.
The App runs OK without any errors. Where are these errors being reported from? It looks as it's a Red Hat response.

Environment

• Operating System: Windows 10
• JDK version: 17.0.13
• Visual Studio Code version: 1.94.2
• Java extension version: 1.35.1 (Language Support for Java by Red Hat.

Steps To Reproduce

Just load the folder containing the HelloWorld.java file into VSCode and the errors show up straight away.
Run the app with or without the debugger and it runs ok.

Source, (java file):
HelloWorld.txt

Log.pdf

settings:
settings.json

Current Result

indicates that package does not exist event though it builds ok.

Expected Result

no linting errors.

Additional Information

let me know what else I can provide

まず、添付された HelloWorld.java ソースと settings.json があるフォルダーを VS Code で読み込み、その後エラーと Log.pdf を調べます。エディターのパッケージが見つからないという診断結果を、コマンドラインでのビルドおよび実行時の動作と比較します。外部 JAR が Java 拡張機能によって認識され、対応する linting エラーが表示されなくなれば完了です。
