netty: netty-all 4.1.64 has a broken dependency graph

Expected behavior

When maven compile (or install) runs on a maven project using both dependencies below, it should not generate errors with dependencies cannot be resolved.

Actual behavior

It generates errors such as:

ERROR] Failed to execute goal on project testNetty64: Could not resolve dependencies for project org.example:testNetty64:jar:1.0-SNAPSHOT: The following artifacts could not be resolved: io.netty:netty- tcnative:jar:${os.detected.classifier}:2.0.39.Final, io.netty:netty-transport-native- epoll:jar:${os.detected.name}-${os.detected.arch}:4.1.64.Final: Could not find artifact io.netty:netty- tcnative:jar:${os.detected.classifier}:2.0.39.Final in MavenCentral (https://repo.maven.apache.org/maven2) -> [Help 1]

Steps to reproduce

Simple pom.xml as below:

  <?xml version="1.0" encoding="UTF-8"?>
  <project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>testNetty64</artifactId>

    <properties>
      <maven.compiler.source>8</maven.compiler.source>
      <maven.compiler.target>8</maven.compiler.target>
    </properties>
  
    <dependencies>
      <dependency>
        <groupId>io.netty</groupId>
        <artifactId>netty-all</artifactId>
        <version>4.1.64.Final</version>
      </dependency>
      <dependency>
        <groupId>io.netty</groupId>
        <artifactId>netty-tcnative</artifactId>
        <version>2.0.39.Final</version>
      </dependency>
    </dependencies>
  </project>

maven clean compile

Netty version

Replacing 4.1.64-Final by 4.1.63-Final runs fine.

With 4.1.64-Final: mvn clean compile -U
