未能下载版本清单，找不到服务器jar URL。安装时出错
/*我已经尝试将creeperhosts证书添加到java的cacert中。请记住，我对这件事没有任何经验……：DDDDD所以我只能听从你的指示。*/
在花了一些时间试图找到解决方案后，我打开了安装程序的代码，找到了安装程序试图用来下载minecraft服务器文件的URL。
public static final String MANIFEST_URL = "https://launchermeta.mojang.com/mc/game/version_manifest.json";
因此，您必须从此链接导出根证书，并将其导入JRE可信证书文件夹。证书名称是"；DigiCert Global Root G2"；。这样做的命令是：
keytool.exe -import -alias digicert -keystore 'C:Program FilesJavajre1.8.0_51libsecuritycacerts' -file 'C:Users[you user here]DownloadsDigiCert Global Root G2.crt'
通常，密钥库的密码是"；changeit"；(去掉引号(。
现在您可以运行安装程序，它应该可以正常工作。
