Question

在尝试将我的Spring MVC Application war文件部署到Heroku时，我收到了java.lang.OutofMemoryError Exception。这个例外可能是什么原因？我做错了什么？

我是heroku-deploy插件的维护者。我已经增加了该工具的默认堆大小，因此如果您通过运行heroku plugins:install https://github.com/heroku/heroku-deploy重新安装它然后再次部署，它将有希望工作。

如果其他人继续遇到这种情况，您可以通过将JAVA_TOOL_OPTIONS环境变量设置为-Xmx2g来手动增加堆大小。
