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.chenenyu:img-optimizer-gradle-plugin:1.2.0'
	}

	dependencies {
		implementation("com.github.chenenyu:img-optimizer-gradle-plugin:1.2.0")
	}

	<dependency>
	    <groupId>com.github.chenenyu</groupId>
	    <artifactId>img-optimizer-gradle-plugin</artifactId>
	    <version>1.2.0</version>
	</dependency>


                            
    libraryDependencies += "com.github.chenenyu" % "img-optimizer-gradle-plugin" % "1.2.0"


                            
    :dependencies [[com.github.chenenyu/img-optimizer-gradle-plugin "1.2.0"]]

How to use

Add the following Gradle configuration to your build.gradle:

buildscript {

        mavenCentral()
    }
    dependencies {

Double click to execute the task.

Configuration

You can add the following options to custom the task:

optimizerOptions {
    triggerSize 5
    type "lossy"
    suffix "_opt"
}

triggerSize Used for filtering pictures. Picture whose size is less than this option will be ignored. Defaults to 0.
type Now supports"lossy" and "lossless"。"lossy" means extreme compression(recommend, default, fast, effective)，"lossless" means loseless compression(slow, inefficient)。
suffix The suffix of the picture which has been optimized. If "_opt"，the optimizer will generate a new picture orignal_opt.png for original.png. Defaults to null.

Preview

|Original png|Extreme compression(lossy)|Loseless compression(lossless)| |:---:|:---:|:---:| |526K|195K(reduce 63%)|473K(reduce 10%)| || 极限压缩 | 无损压缩 |

Note

If there are multiple modules in your project, please add the optimizer in where you want to execute optimization since each module is independent. The optimizer will generate log file in the root directory of current module.
