推荐答案
无法转移工件 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
看来您的Maven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Internet连接.
- 检查是否可以访问默认的Maven存储库 http://repo.maven.apache.org/maven2 在您的浏览器中.
- 检查
settings.xml
中
<repositories>
和<proxies>
中的配置是否正确
- 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 yoursettings.xml
