我 正在 尝试 使用 Gradle 部署 Java 应用 程序 ， 并且 能够 执行 所有 部署 步骤 ， 但是 当 我 在 部署 后 编写 heroku open 时 ， 屏幕 会 保持 白色 一 段 时间 ， 然后 日志 返回 错误

2022-10-10T05:52:17.000000+00:00 app[api]: Build succeeded
2022-10-10T05:53:40.640805+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 90 seconds of launch
