generic

解决方案

  1. 95% 成功率 Import the mirror's SSL certificate into the Java truststore 
    keytool -import -alias mirror -keystore $JAVA_HOME/lib/security/cacerts -file mirror.crt
  2. 90% 成功率 Use HTTPS with a trusted certificate or switch to HTTP if allowed 
    <mirror><id>internal</id><url>http://internal-mirror.com/maven2</url><mirrorOf>central</mirrorOf></mirror>

无效尝试

常见但无效的做法:

  1. Disabling SSL verification globally in settings.xml 80% 失败

    This is a security risk and may not be allowed in corporate environments.

  2. Using a different mirror without verifying its certificate 90% 失败

    The new mirror may have the same issue or be malicious.
