Stackdriver exporter doesn't work in mac

[kanjih]

Stackdriver exporter doesn't work in mac.
When I run the app with stackdriver configuration, no io_grpc_netty_shaded_netty_tcnative_osx_x86_64 in java.library.path error happens.

What version of OpenCensus are you using?

• 0.27.0 (gradle setting is the below)

compile 'io.opencensus:opencensus-api:0.27.0'
compile 'io.opencensus:opencensus-exporter-trace-stackdriver:0.27.0'
runtime 'io.opencensus:opencensus-impl:0.27.0'

What JVM are you using (java -version)?

java version "1.8.0_172"

What did you do?

Run the code below, I can reproduce the error every time.

Code

@SpringBootApplication
@EnableScheduling
public class App {
	public static void main(String[] args) {
		try {
			StackdriverTraceExporter.createAndRegister(StackdriverTraceConfiguration.builder().setProjectId("my-project-id").build());
		} catch (IOException e) {
			throw new UncheckedIOException(e);
		}
		SpringApplication.run(App.class, args);
	}
}

build.gradle

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "org.springframework.boot:spring-boot-gradle-plugin:2.1.2.RELEASE"
    }
}

apply plugin: 'idea'
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group 'xxx'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    compile 'io.opencensus:opencensus-api:0.27.0'
    compile 'io.opencensus:opencensus-exporter-trace-stackdriver:0.27.0'
    runtime 'io.opencensus:opencensus-impl:0.27.0'
    compileOnly 'org.projectlombok:lombok:1.18.12'
    annotationProcessor 'org.projectlombok:lombok:1.18.12'
    testCompileOnly 'org.projectlombok:lombok:1.18.12'
    testAnnotationProcessor 'org.projectlombok:lombok:1.18.12'

}

What did you expect to see?

No error
