Maven Dependencies Jar Missing for Slf4j wrapper - jar

Question

I have a project in Maven for ExtentReports. When I run it, the test fail and says.
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
When I check the project properties -> java build path -> libraries. ->Maven Dependencies
rxjava-3.0.4.jar (missing)
freemarker-2.3.30.jar (missing)
lombok-1.18.12.jar (missing)
when I go to POM.xml
4.0.0
it says:
could not transfer artifact io.reactivex.rxjava3:rxjava:jar3.0.4
I tried downloading the said jars in mvn repository but it doesnt make any changes.

SLF4j wrapper is generally provided by Lombok.
I recommend you put these dependencies in your pom.xml:
You need the SLF4j wrapper AS WELL AS a dependency for which implementation you want to use. (Logback in this case).
<!--region Lombok Configuration -->
<!-- logger guide https://gist.github.com/stykalin/8c77ad2a705eabddc2424eff0e99d1ec -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.22</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.2.11</version>
</dependency>
<!-- endregion -->
Also, you will need to setup a src/main/resources/logback.xml file. Also, put #Slf4j Lombok annotation at the top of your class files where you need to do a log.info("Message").
IF you still have problems, the command mvn dependency:tree can perhaps help you find dependency conflicts.
