推荐答案

无法转移神器org.apache.maven.plugins:maven-dependency-plugin:pom:2.8 from/to中央(http://repo.maven.apache.org/maven2):repo.maven.apache.org:未知主机 repo.maven.apache.org

Could not transfer artifact org.apache.maven.plugins:maven-dependency-plugin:pom:2.8 from/to central (http://repo.maven.apache.org/maven2): repo.maven.apache.org: Unknown host repo.maven.apache.org

您的 Maven 似乎无法访问远程中央存储库.

It seems like your maven cannot access remote central repository.

• 检查您是否已建立互联网连接.
• 检查您是否可以访问默认的 maven repo http://repo.maven.apache.org/maven2 在浏览器中.
• 检查您的 和 中的配置是否正确，settings.xml

• Check if you have an established internet connection.
• Check if you can access default maven repo http://repo.maven.apache.org/maven2 in your browser.
• Check if you have correct configuration in <repositories> and <proxies> in your your settings.xml
