Intellij中的龙目岛注释

Question

I have trouble with using Lombok's annotations, cause it seems like jar wasn't even imported to project:

import lombok.extern.slf4j.Slf4j;

/**
 * Created by John on 2017-03-20.
 */
@Slf4j
public class App {

    public static void main(String[] args)
    {
        log.info("Hello");
    }
}

It says:

Cannot resolve method info(java.lang.String)

When compiling:

Error:(6, 1) java: package org.slf4j does not exist

I did:

1. Insert lombok's dependency into pom
2. Installed lombok plugin for Intellij
3. Enabled annotations processing
4. Imported dependencies to project (they are on external libs list)

I've looked for a solution here:

• Lombok added but getters and setters not recognized in Intellij IDEA
• Can't compile project when I'm using Lombok under IntelliJ IDEA
• Building with Lombok's @Slf4j and Intellij: Cannot find symbol log

Still the same problem. Any advice would be appriciated.

UPDATE: pom.xml if it helps:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

    </dependencies>


</project>

Answer 1

You also need to add at least the slf4j-api dependency to your project.

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>${slf4j.version}</version>
</dependency>

Answer 2

You need to:

1. Add lombok to your dependency, and make sure the package is downloaded properly.
2. Install the lombok plugin for Intellij.

3. Enable annotation processing in Intellij: Preferences -> Build,Execution,Deployment -> Compiler -> Annotation Processors -> Enable Annotation processing.

4. Restart Intellij.
