java - Heroku 部署失败

Question

我正在使用 Play 框架和 Java 1.7。

上次部署:

-----> Play! app detected

-----> Installing OpenJDK 1.7... done

-----> Building Play! application...

这次部署:

-----> Play! app detected /app/tmp/buildpacks/85dfc1d8f48aec0b42f03a59461dc516a918eb099c9e908767a7f42ddf326e12e48c6030ff4891e5c63f08e3b760ea09dee5bbfa4ca293b152d266406bfa29b3/bin/compile: line 31: detect_java_version: command not found

如何解决？

Answer 1

首先请注意Heroku no longer supports Play 1.x 。如果可以，请考虑将您的应用程序升级到 Play 2.x，which is still supported .

但是，您描述的问题 has now been fixed 。现已弃用的 Play 1.x 构建包的依赖项破坏了向后兼容性。重新部署您的应用程序应该无需您做任何工作即可完成。
