我已经从maven.oracle.com网站（* .oracle.com）安装了证书到以下商店：
/etc/ssl/cacerts/trustStore (defined in Global MAVEN_OPTS with correct passwd)
/home/jenkins/cacerts
/etc/pki/ca-trust/extracted/java/cacerts
/etc/pki/java/cacerts
/etc/ssl/cacerts
/usr/java/jdk1.8.0_192-amd64/jre/lib/security/cacerts
/usr/java/jdk-11.0.1/lib/security/cacerts
/opt/oracle/12.2/client64/jdk/jre/lib/security/cacerts
Jenkins已安装JDK8和JDK11，此版本配置为使用JDK8。
在商店上使用keytool会显示* .oracle.com证书，该证书将使用maven.oracle.com的别名进行安装。
获取证书的命令是：
keytool -printcert -rfc -sslserver maven.oracle.com
然后将其复制并粘贴到vi中以创建证书文件。
安装证书的命令采用以下格式：
keytool -import -file maven.oracle.com.cer -alias maven.oracle.com -keystore /opt/oracle/12.2/client64/jdk/jre/lib/security/cacerts
我尝试运行的Jenkins构建作业仍然失败，并出现证书错误：

我不明白为什么未从任何商店中提取证书。我以前为另一个证书做了此操作，并且按预期工作。
有人可以指出正确的方向来解决这个问题吗？
