Cannot find the class file for javax.servlet.http.HttpServletResponse.

• Operating System: Ubuntu 20.04
• JDK version: openjdk 11.0.11
• Visual Studio Code version: 1.60.1
• Java extension version: v0.82.0

I have a java project that uses gradle. This project worked well with the java extension for a long time.

Now, when I run './gradlew assemble' from the command line, the project builds successfully.

When I load the project in VSCode I get the following errors...

{
	"resource": "/myproj//java_server",
	"owner": "_generated_diagnostic_collection_name_#1",
	"code": "0",
	"severity": 8,
	"message": "The project was not built since its build path is incomplete. Cannot find the class file for javax.servlet.http.HttpServletResponse. Fix the build path then try building this project",
	"source": "Java",
	"startLineNumber": 1,
	"startColumn": 1,
	"endLineNumber": 1,
	"endColumn": 1
}

}

Inizia riproducendo lo stato del progetto segnalato in VS Code con JDK 11 e la versione indicata dell’estensione Java, quindi confrontalo con il comando ./gradlew assemble eseguito correttamente. Esamina come l’estensione gestisce il percorso di build del progetto Gradle e il riferimento da src/main/java/framework/MessageHandler.java; il lavoro è completato quando il progetto viene caricato senza le diagnostiche relative alla mancanza di javax.servlet.http.HttpServletResponse.
