Answer

First make sure you didn’t make any typos in your import statement.

If that didn’t fix it there are 2 possible solutions I can think of:

Solution 1

You probably haven’t added this plugin to your classpath inside of the java project.

To do this right-click on your project (inside of the project explorer) and press Properties.

If you’ve done everything correctly there should popup another window where you can search for “Java Build Path”.

Click on it and then go to the Libraries tab. Since I don’t know what file type the plugin is I’m assuming it’s a .jar file. Click on the “Add JARs” button and select the plugin file.

Solution 2

If you use a maven project you probably haven’t configured the plugin dependency inside your pom.xml file.

Just open the file and add the dependency. In the end it could look like this:

<dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-jdk14</artifactId>
        <version>2.0.0-alpha5</version>
        <scope>runtime</scope>
</dependency>

I hope I understood your problem correctly and this answer helps you to solve this problem.
