zip file too large aws lambda java gradle

问题

我想在 AWS Lambda 上部署我的 Java 函数。

我查看了这个文档 https://docs.aws.amazon.com/lambda/latest/dg/java-package.html。

这是我的 build.gradle 文件：

  1. plugins {
  2.     id 'java'
  3.     id 'org.jetbrains.kotlin.jvm' version '1.3.61'
  4. }
  6. group 'com.xxx'
  7. version '1.0'
  9. sourceCompatibility = 1.8
  11. repositories {
  12.     mavenCentral()
  13. }
  15. dependencies {
  16.     implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
  17.     implementation "org.jetbrains:annotations:16.0.2"
  18.     implementation 'com.amazonaws:aws-lambda-java-core:1.2.0'
  19.     implementation 'com.amazonaws:aws-lambda-java-events:2.2.7'
  20.     implementation 'com.google.code.gson:gson:2.8.6'
  22.     compile group: 'org.bytedeco', name: 'javacv-platform', version: '1.5.2'
  24.     runtimeOnly 'com.amazonaws:aws-lambda-java-log4j2:1.1.0'
  26.     testCompile group: 'junit', name: 'junit', version: '4.12'
  27. }
  29. jar {
  30.     manifest {
  31.         attributes 'Main-Class': 'Main'
  32.     }
  33. }
  35. task fatJar(type: Jar) {
  36.     manifest {
  37.         attributes 'Implementation-Title': 'Gradle Jar File Example',
  38.                 'Implementation-Version': archiveVersion,
  39.                 'Main-Class': 'Main'
  40.     }
  41.     baseName = project.name + '-all'
  42.     from sourceSets.main.output
  44.     dependsOn configurations.runtimeClasspath
  45.     from {
  46.         configurations.runtimeClasspath.findAll { it.name.endsWith('jar') }.collect { zipTree(it) }
  47.     }
  48.     with jar
  49. }
  51. task buildZip(type: Zip) {
  52.     manifest {
  53.         attributes (
  54.                 'Implementation-Title': 'AWS Handler',
  55.                 'Implementation-Version': archiveVersion,
  56.                 'Main-Class': 'AWSHandler'
  57.         )
  58.     }
  60.     from compileJava
  61.     from processResources
  62.     into('lib') {
  63.         from configurations.runtimeClasspath
  64.     }
  65. }
  67. compileKotlin {
  68.     kotlinOptions.jvmTarget = "1.8"
  69. }
  70. compileTestKotlin {
  71.     kotlinOptions.jvmTarget = "1.8"
  72. }

我运行 gradle buildZip 命令来构建我的压缩文件。实现了 RequestHandler 的 AWS 类位于 src/main/java/AWSHandler.java。

一旦命令成功结束，我得到一个 710MB 的压缩文件，这太大了！！！
当我解压文件时，我可以看到有很多库来支持许多操作系统。

根据这个文档 https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html，似乎 Java 8 函数在 Amazon Linux 上运行。

所以我可以清理我的压缩文件，只保留这个操作系统。

我能用 Gradle 做到吗，还是应该创建一个额外的脚本来清理我的文件？

英文:

I would like to deploy my java function on aws lambda

I took this documentation https://docs.aws.amazon.com/lambda/latest/dg/java-package.html

This is my build.gradle file

  1. plugins {
  2. id 'java'
  3. id 'org.jetbrains.kotlin.jvm' version '1.3.61'
  4. }
  5. group 'com.xxx'
  6. version '1.0'
  7. sourceCompatibility = 1.8
  8. repositories {
  9. mavenCentral()
  10. }
  11. dependencies {
  12. implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
  13. implementation "org.jetbrains:annotations:16.0.2"
  14. implementation 'com.amazonaws:aws-lambda-java-core:1.2.0'
  15. implementation 'com.amazonaws:aws-lambda-java-events:2.2.7'
  16. implementation 'com.google.code.gson:gson:2.8.6'
  17. compile group: 'org.bytedeco', name: 'javacv-platform', version: '1.5.2'
  18. runtimeOnly 'com.amazonaws:aws-lambda-java-log4j2:1.1.0'
  19. testCompile group: 'junit', name: 'junit', version: '4.12'
  20. }
  21. jar {
  22. manifest {
  23. attributes 'Main-Class': 'Main'
  24. }
  25. }
  26. task fatJar(type: Jar) {
  27. manifest {
  28. attributes 'Implementation-Title': 'Gradle Jar File Example',
  29. 'Implementation-Version': archiveVersion,
  30. 'Main-Class': 'Main'
  31. }
  32. baseName = project.name + '-all'
  33. from sourceSets.main.output
  34. dependsOn configurations.runtimeClasspath
  35. from {
  36. configurations.runtimeClasspath.findAll { it.name.endsWith('jar') }.collect { zipTree(it) }
  37. }
  38. with jar
  39. }
  40. task buildZip(type: Zip) {
  41. manifest {
  42. attributes (
  43. 'Implementation-Title': 'AWS Handler',
  44. 'Implementation-Version': archiveVersion,
  45. 'Main-Class': 'AWSHandler'
  46. )
  47. }
  48. from compileJava
  49. from processResources
  50. into('lib') {
  51. from configurations.runtimeClasspath
  52. }
  53. }
  54. compileKotlin {
  55. kotlinOptions.jvmTarget = "1.8"
  56. }
  57. compileTestKotlin {
  58. kotlinOptions.jvmTarget = "1.8"
  59. }

So I am running gradle buildZip to build my zip, my aws class implementing RequestHandler is in src/main/java/AWSHandler.java

Once the command ended with success I have a 710MB zip file, this is huge !!!
When I am unzipping the file I can see that there are many libs to support many os

压缩文件太大 AWS Lambda Java Gradle

Flowing this doc https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html seems that java8 functions are running on Amazon Linux

So I could clean my zip to only get this os

Can I do it with gradle or should I create an extra script to clean my file ?

Zip任务类型的into方法可以接受一个CopySpec，您可以使用该CopySpec来添加排除项：

链接：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)

  1. into('lib') {
  2.     from configurations.runtimeClasspath
  3.     exclude("**windows**") // 示例，未经测试。
  4. }

有关更多详细信息，请参阅Javadoc：https://docs.gradle.org/current/javadoc/org/gradle/api/file/CopySpec.html

英文:

The into method of the Zip task type can accept a CopySpec which you can use to add exclusions:

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)

  1. into('lib') {
  2. from configurations.runtimeClasspath
  3. exclude("**windows**") // example, untested.
  4. }

See the Javadoc for more details: https://docs.gradle.org/current/javadoc/org/gradle/api/file/CopySpec.html
