Suppress Specific Warnings. Ex: "The serializable class [class name] does not declare a static final serialVersionUID field of type long"

[ozyman42]

Currently I'm trying to suppress a warning that is appearing all over my project in multiple different classes:

The serializable class [class name] does not declare a static final serialVersionUID field of type long

I know in other IDEs such as IntelliJ and Eclipse, this specific warning can be suppressed for all Java projects. What would be the equivalent operation in VSCode + Language Support for Java extension.

The following are reasons why I cannot declare a serialVersionUID or use @SuppressWarnings, and instead need to suppress the warning for all files open in the VSCode editor:

1. Writing the @SuppressWarnings would force me to modify code which I am not allowed to modify. The prof only wants students to implement certain areas of the framework.

2. I would need to make these changes to about 30 classes which is less than ideal.

Environment

• Operating System: Windows 10
• JDK version: 1.8
• Visual Studio Code version: 1.21.1
• Java extension version: 0.22.0

Steps To Reproduce

1. Create Java project
2. Create class which extends Serializable.

Example below of Messages.java, where Message extends Serializable.

package dslabs.pingpong;

import dslabs.framework.Message;
import dslabs.pingpong.PingApplication.Ping;
import dslabs.pingpong.PingApplication.Pong;
import lombok.Data;

@Data
class PingRequest implements Message {
	private final Ping ping;
}

@Data
class PongReply implements Message {
	private final Pong pong;
}

In VSCode, I see that PingRequest and PongReply are both underlined in red.

Current Result

Class name has red underline beneath it. VS Code claims that there is an error because a static final serialVersionUID is not present in the class

Expected Result

There should be a way, such as a setting, where certain particular warnings can be suppressed for all java projects. This feature is available in Eclipse and IntelliJ

Ideally I could modify an extension configuration variable such as:

java.suppressedWarnings = ["serial"]

vscode-java doesn't currently expose a way to change messages severity. You need to manually tweak your project's .settings/org.eclipse.jdt.core.prefs as explained in
eclipse-jdtls/eclipse.jdt.ls#581 (comment)
