我正在学习使用库的 JNI，教程是https://www.baeldung.com/jni。java源文件是

package zxy;

public class JNIDemo {
    public native void testHello();

    public static void main(String[] args){
        System.loadLibrary("native");
        JNIDemo jniDemo = new JNIDemo();
        jniDemo.testHello();
        System.out.println("zxy");
    }
}

项目目录是：

/src/main/java/zxy
       |->JNIDemo.java
/libs
  |-> libnative.so
build.gradle
gradlew
settings.gradle

build.gradle 文件是

plugins {
    id 'application'
}

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

repositories {
    mavenCentral()
}

application {
    mainClass = 'zxy.JNIDemo'
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
    implementation files('libs/libnative.so')
}

和 settings.gradle 是

rootProject.name = 'jni'

当我运行时./gradlew installDist，它工作正常，并提供以下目录结构

build/
|-> /install/jni
        |-> /bin
               |-> jni
               |-> jni.bat
        |-> /lib
               |-> jni-1.0-SNAPSHOT.jar
               |-> libnative.so

但是当我跑的时候build/install/jni/bin/jni，我给了我

Exception in thread "main" java.lang.UnsatisfiedLinkError: no native in java.library.path
        at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1860)
        at java.lang.Runtime.loadLibrary0(Runtime.java:871)
        at java.lang.System.loadLibrary(System.java:1124)
        at zxy.JNIDemo.main(JNIDemo.java:8)

FAILURE: Build failed with an exception.

我不明白为什么，如何在命令中包含 java.library.pathgradlew installDist
