netty: Unable to load io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider

Expected behavior

Spring Cloud Gateway microservice (api-gateway) should route to appropriate microservice (web) using Eureka Discovery Server microservice (discovery) and return “Hello World”.

Actual behavior

Adding this resolved my issue with M1. This <classifier>osx-x86_64</classifier> did not work until i switched to below.


  <dependency>
      <groupId>io.netty</groupId>
      <artifactId>netty-resolver-dns-native-macos</artifactId>
      <version>4.1.73.Final</version>

@normanmaurer do you have any workaround or any idea when M1 will be supported?

use below dependency for M1 based mac, it works for me. implementation ‘io.netty:netty-resolver-dns-native-macos:4.1.72.Final:osx-aarch_64’

make sure you have:

        <dependency>
          <groupId>io.netty</groupId>
          <artifactId>netty-resolver-dns-native-macos</artifactId>
          <version>XXX</version>
          <classifier>osx-x86_64</classifier>
        </dependency>

in your class path on OS X

Doesn’t fix the issue anymore.

Same problem with M1 macbook. Tried this but didn’t help:

<dependency>
                <groupId>io.netty</groupId>
                <artifactId>netty-resolver-dns-native-macos</artifactId>

                <classifier>osx-aarch_64</classifier>
</dependency>

works fine for me on spring boot 2.5.3

I still get this issue on an Apple M1. I guess there needs to be a DnsServer provider that supports the M1?

You could also use the following code to fix an error

    <artifactId>netty-all</artifactId>
</dependency>

For maven and a project where this is only needed for local development on machines running mac M1 you can use a profile activated based on the OS:

        <profile>
            <id>macos-m1</id>
            <activation>
                <os>
                    <family>mac</family>
                    <arch>aarch64</arch>
                </os>
            </activation>
            <dependencies>
                <dependency>
                    <groupId>io.netty</groupId>
                    <artifactId>netty-resolver-dns-native-macos</artifactId>
                    <classifier>osx-aarch_64</classifier>

@normanmaurer do you have any workaround or any idea when M1 will be supported?

I use implementation(group = “io.netty”,name = “netty-resolver-dns-native-macos”, version = “4.1.70.Final”, classifier = “osx-aarch_64”)

techwn on Dec 5, 2021

@singulart As far as I can see the code will only be loaded on an ARM Mac and it’s also a pretty small library, so it should be harmless to add the dependency by default. Or, assuming your CI hardware is not ARM Mac, you can add the dependency only when building on ARM Macs using an auto-activating Maven profile like this:

<profile>
  <id>netty-resolver-dns-native-macos-aarch64</id>
  <activation>
    <os>
      <family>mac</family>
      <arch>aarch64</arch>
    </os>
  </activation>
  <dependencies>
    <dependency>
      <groupId>io.netty</groupId>
      <artifactId>netty-resolver-dns-native-macos</artifactId>
      <classifier>osx-aarch_64</classifier>
    </dependency>
  </dependencies>
</profile>

Sorry missed this one. We added supported in the last release (4.1.68.Final).

I still have the same issue.

this works for me implementation 'io.netty:netty-all' implementation(group: "io.netty", name: "netty-resolver-dns-native-macos", version: "4.1.72.Final", classifier: "osx-aarch_64")

adetiamarhadi on Aug 6, 2022

The dependency has only runtime scope:

runtimeOnly "io.netty:netty-resolver-dns-native-macos:4.1.76.Final:osx-aarch_64"

How can we make this dependency platform agnostic? We don’t really want to have a platform dependency in our java builds.

You could also use the following code to fix an error

use below dependency for M1 based mac, it works for me. implementation ‘io.netty:netty-resolver-dns-native-macos:4.1.72.Final:osx-aarch_64’

nbhhcty on Jan 24, 2022

In Gradle, you can use osdetector-gradle-plugin to fetch dependencies for specific platforms:

// build.gradle.kts

plugins {
    id("com.google.osdetector") version "1.7.1"
}

dependencies {
    if (osdetector.classifier == "osx-aarch_64") {
        runtimeOnly("io.netty:netty-resolver-dns-native-macos:4.1.77.Final:${osdetector.classifier}")
    }

According to https://maven.apache.org/guides/introduction/introduction-to-profiles.html#Profiles_in_POMs Maven profiles can modify <dependencies>.

mac M1 with build.gradle.kts

    testImplementation(
        group = "io.netty",
        name = "netty-resolver-dns-native-macos",
        classifier = "osx-aarch_64"
    )

Thanks! This worked for me. I also locked mine to Mac M1 machines only since we use different kinds of machines here at work:

	def isMacOS = System.getProperty('os.name').startsWith('Mac OS X')
	def architecture = System.getProperty('os.arch').toLowerCase()
	if (isMacOS && architecture == 'aarch64') {
		testImplementation('io.netty:netty-resolver-dns-native-macos:4.1.90.Final:osx-aarch_64')
	}

If you don’t want to include native support properly (arm & intel) you should scope the dependency not as “implementation” but rather as “compileOnly” - (talking gradle slang 😃 and document which dependencies can be included optionally.

For Maven the workaround looks like following: <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-webflux</artifactId> <exclusions> <exclusion> <groupId>io.netty</groupId> <artifactId>netty-resolver-dns-native-macos</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>io.netty</groupId> <artifactId>netty-resolver-dns-native-macos</artifactId> <version>4.1.73.Final</version> <classifier>osx-aarch_64</classifier> </dependency> First exclude the referenced library. And then add it explicit with the classifier. Worked on M2 chip MacBook Pro 2022.

io.netty netty-resolver-dns-native-macos 4.1.73.Final osx-aarch_64 doesnt work on my M1 pro machine with Spring Boot 2.6.1. Are there any updates planned?

Update: io.netty:netty-all:4.1.73.Final works on my M1 pro with Spring Boot 2.6.1

I have this problem on M1 MacOS with Spring boot 2.5.5
