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.methodho:memory-measurer:'
	}
	dependencies {
		implementation("com.github.methodho:memory-measurer:")
	}
	<dependency>
	    <groupId>com.github.methodho</groupId>
	    <artifactId>memory-measurer</artifactId>
	    <version></version>
	</dependency>

                            
    libraryDependencies += "com.github.methodho" % "memory-measurer" % ""
        
        

                            
    :dependencies [[com.github.methodho/memory-measurer ""]]

ObjectExplorer

Fork from DimitrisAndreou/memory-measurer

  1. Rewrite it by using pure Java 8 API instead of Google Guava
  2. Convert it to maven project

How to use

long memory = MemoryMeasurer.measureBytes(new HashMap());

or

Footprint footprint = ObjectGraphMeasurer.measure(new HashMap());

Quick tip

  • mvn clean package - to package jar
  • To use the MemoryMeasurer (to measure the footprint of an object graph in bytes), this parameter needs to be passed to th VM: -javaagent:path/to/object-explorer.jar
