Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.abcelo:abcelo-util-aws-lambda:'
	}
	dependencies {
		implementation("com.github.abcelo:abcelo-util-aws-lambda:")
	}
	<dependency>
	    <groupId>com.github.abcelo</groupId>
	    <artifactId>abcelo-util-aws-lambda</artifactId>
	    <version></version>
	</dependency>

                            
    libraryDependencies += "com.github.abcelo" % "abcelo-util-aws-lambda" % ""
        
        

                            
    :dependencies [[com.github.abcelo/abcelo-util-aws-lambda ""]]

Readme

abcelo-util-aws-lambda

For those building AWS Lambda Functions with libraries that log using SLF4J, or who want to use SLF4J and conventional logging in their own code, we offer abcelo-util-aws-lamba's LambdaAppender class. Please see the example usage and logback.xml file below.

Example Lambda Handler

import com.amazonaws.services.lambda.runtime.Context
import org.slf4j.LoggerFactory

class TestLambdaHandler {
  import TestLambdaHandler._

  def doStuff(context: Context): Unit = {
    LambdaAppender.setContext(context)
    log.info("Hi!")
  }
}

object TestLambdaHandler {
  val log = LoggerFactory.getLogger(getClass)
}

Example logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <appender name="lambda" class="LambdaAppender">
    <encoder>
      <pattern>%n&gt;&gt;&gt;&gt;&gt; %d{yyyy-MM-dd'T'HH:mm:ss.SSS'Z'}: %-5p [%t] %C.%M [%F:%L]%n%m%n</pattern>
    </encoder>
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
      <level>info</level>
    </filter>
  </appender>
  <root level="info">
    <appender-ref ref="lambda"/>
  </root>
</configuration>
