添加 JavaCV 作为依赖项，以便在 Raspberry PI 上运行？

Question

JavaCV documentation says I should use this to add JavaCV as a dependency to my project;

dependencies {
    implementation group: 'org.bytedeco', name: 'javacv-platform', version: '1.5.4'
}

The problem with this is that this includes all kinds of crap like runtime libs for Mac, Android, Windows, etc.

Which dependencies do I need to use JavaCV in my project, in a more non-bloated fashion?

Answer 1

After some research I've found that this is easily done using the "platform plugin of Gradle JavaCPP":

http://bytedeco.org/builds/

https://github.com/bytedeco/gradle-javacpp#the-platform-plugin

Using said plugin you can specify the target platform with : gradle -PjavacppPlatform=linux-armhf and only the needed platform dependencies will be used.

You also can look at the example:

https://github.com/bytedeco/gradle-javacpp/tree/master/samples/javacv-demo

I've tried building the example and a uber-jar of "only" around 100Mb is generated.

I think you could also add some exclusions to eliminate unneeded libs and further reduce the size of the jar.
