java - zip文件太大aws lambda java gradle

Question

我想在AWS Lambda上部署我的Java函数

我拿了这份文档https://docs.aws.amazon.com/lambda/latest/dg/java-package.html

这是我的build.gradle文件

plugins {
    id 'java'
    id 'org.jetbrains.kotlin.jvm' version '1.3.61'
}

group 'com.xxx'
version '1.0'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    implementation "org.jetbrains:annotations:16.0.2"
    implementation 'com.amazonaws:aws-lambda-java-core:1.2.0'
    implementation 'com.amazonaws:aws-lambda-java-events:2.2.7'
    implementation 'com.google.code.gson:gson:2.8.6'

    compile group: 'org.bytedeco', name: 'javacv-platform', version: '1.5.2'

    runtimeOnly 'com.amazonaws:aws-lambda-java-log4j2:1.1.0'

    testCompile group: 'junit', name: 'junit', version: '4.12'
}

jar {
    manifest {
        attributes 'Main-Class': 'Main'
    }
}

task fatJar(type: Jar) {
    manifest {
        attributes 'Implementation-Title': 'Gradle Jar File Example',
                'Implementation-Version': archiveVersion,
                'Main-Class': 'Main'
    }
    baseName = project.name + '-all'
    from sourceSets.main.output

    dependsOn configurations.runtimeClasspath
    from {
        configurations.runtimeClasspath.findAll { it.name.endsWith('jar') }.collect { zipTree(it) }
    }
    with jar
}

task buildZip(type: Zip) {
    manifest {
        attributes (
                'Implementation-Title': 'AWS Handler',
                'Implementation-Version': archiveVersion,
                'Main-Class': 'AWSHandler'
        )
    }

    from compileJava
    from processResources
    into('lib') {
        from configurations.runtimeClasspath
    }
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

所以我正在运行 gradle buildZip来构建我的zip，实现 RequestHandler的aws类在 src/main/java/AWSHandler.java中

命令成功结束后，我有一个710MB的zip文件，这真是太棒了!
解压缩文件时，我可以看到有很多库可以支持许多操作系统



传递此文档 https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html似乎在 Amazon Linux上运行了Java8函数

所以我可以清洁我的 zipper ，只得到这个操作系统

我可以用gradle来做吗，还是应该创建一个额外的脚本来清理文件？

into任务类型的Zip方法可以接受CopySpec，可用于添加排除项:

https://docs.gradle.org/current/dsl/org.gradle.api.tasks.bundling.Zip.html#org.gradle.api.tasks.bundling.Zip:into(java.lang.Object,%20org.gradle.api.Action)

into('lib') {
    from configurations.runtimeClasspath
    exclude("**windows**") // example, untested.
}
