Sbt plugin for projects with jni sources

sbt-jni

Sbt plugin for projects with jni sources.

On compile, the jniCompile task will be run. It first runs the javah task, which generates JNI headers. Headers generated for jni classes will end up in headersPath, which defaults to target/native/include. The final library will be in binPath, which defaults to target/native/bin.

Install

resolvers += Resolver.url("joprice maven", url("http://dl.bintray.com/content/joprice/maven"))(Resolver.ivyStylePatterns)

addSbtPlugin("com.github.joprice" % "sbt-jni" % "0.1.0")

Usage

Native sources should be placed in nativeSource, which defaults to src/main/native.

import com.github.joprice.Jni
import Jni.Keys._

Jni.settings

// this will be the name that you call `System.loadLibrary` with, prefixed with "lib"
libraryName := "libMyApp"

gccFlags ++= Seq("-lpthread")

// defaults to gcc
nativeCompiler := "g++"

jniClasses := Seq(
  "com.myapp.ClassWithJniCode"
)

Caveats

Only tested on Centos, g++, with cpp and java jni sources.
