Gradle snippet:
build.gradle
dependencies {
    implementation 'org.slf4j:slf4j-api:1.7.30'
    implementation 'org.slf4j:slf4j-simple:1.7.30'
}Add to your code (where the Test class is your code):
Test.java
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
class Test {
    private static final Logger logger = LoggerFactory.getLogger(Test.class);Log levels
From the manual:
- trace
- error
- warn
- info
- debug
No "panic", no "warning"!
