解决方案 #

1. 修复PKIX证书信任问题 #

这是核心报错原因，Java无法验证Maven Central的SSL证书，处理步骤：

• 导出Maven Central的根证书：访问对应网站，通过浏览器地址栏的锁图标查看证书，导出为.crt格式文件。
• 将证书导入Java信任库：
  打开终端执行命令（替换证书路径）：

  sudo keytool -import -trustcacerts -file /path/to/your/certificate.crt -keystore $JAVA_HOME/jre/lib/security/cacerts
  

  默认信任库密码为changeit，输入密码后确认导入即可。

2. 配置Gradle TLS协议（可选） #

若证书导入后仍有TLS相关报错，可指定兼容协议：

• 在项目根目录创建gradle.properties文件，添加：

  systemProp.jdk.tls.client.protocols=TLSv1.2,TLSv1.3
  systemProp.https.protocols=TLSv1.2,TLSv1.3
  

  或临时通过命令指定：

  gradle run -Djdk.tls.client.protocols=TLSv1.2,TLSv1.3 -Dhttps.protocols=TLSv1.2,TLSv1.3
  

3. 检查网络代理配置（若有） #

如果处于代理环境，需在gradle.properties中添加代理信息：

systemProp.http.proxyHost=你的代理地址
systemProp.http.proxyPort=你的代理端口
systemProp.https.proxyHost=你的代理地址
systemProp.https.proxyPort=你的代理端口

若代理需要认证，补充：

systemProp.http.proxyUser=你的代理用户名
systemProp.http.proxyPassword=你的代理密码
systemProp.https.proxyUser=你的代理用户名
systemProp.https.proxyPassword=你的代理密码
