Including only specific OS libs in boot jar

[Abhishek Yadav]

Hello There,

I am using platformcv to stream from rtps stream and do further processing using javacv. 

Currently bootjar is containing libs for all OS including windows/mac/linux which is making size of the jar file huge. I am looking for a way to keep libs only for specific OS. Can you please suggest how can I achieve that.

below is content of gradle here for reference:

plugins {
id "org.springframework.boot" version "3.0.4"
id 'java'
id 'org.bytedeco.gradle-javacpp-platform' version "1.5.8"
}

group 'org.example'
version '1.0-SNAPSHOT'

repositories {
mavenCentral()
}
ext {
javacppPlatform = 'macosx-arm64' // or any other platform, defaults to Loader.getPlatform()
}

tasks.jar {
enabled = false
archiveClassifier.set("")
}

bootJar {
archiveBaseName = "video_streaming_poc"
archiveVersion = "1.0.0"
}

dependencies {

// https://mvnrepository.com/artifact/org.bytedeco/javacv
implementation group: 'org.bytedeco', name: 'javacv-platform', version: '1.5.8'


}

If you're using Gradle, setting the javacppPlatform property like you're doing will do what you want. Could you maybe rephrase your question?

Hello Samuel,

Thanks for your email, yes the gradle setting I took from your git page itself. If you noticed, I am only specifying macosx-arm64 as javacppplatform but still it’s downloading all dependencies for other os as well, and when I am building bootjar, its containing these additional dependencies of other os which is contributing in its size.

Ideally it should download only macos related libs which is not happening. I am using ffmpeg libs to convert rtsp streams to file.

Maybe there's a conflict with the plugin for Spring Boot. Could you try
without Spring Boot see if it does the same thing or not?
