我在Heroku上的app slug大小表示222 MB。非常庞大，超出200MB的允许范围。
因此，我已经检查了这些事情：
检查我的源代码大小： 89,9 Mo 知道 80,2 Mo 来自播放应用的目标文件夹
检查我的.gitignore文件，确保播放应用的目标文件夹排除在外。这是我的.gitignore文件：
.DS_Store logs project/project project/target target // target well precised here tmp .history dist /.idea / *.iml //space here otherwise appears as a comment here /out /.idea_modules /.classpath /.project /RUNNING_PID /.settings
检查我的SBT常春藤缓存大小： 100,9 Mo
这里详细说明了每个文件夹的大小（左侧）：

我的SBT构建文件包含以下依赖项：

我可以做些什么来减少这个巨大的slu size尺寸？即使我删除了一些文件和罐子来源，尺寸也会很大。
尽管.gitignore文件
当然，我已经使用这个buildpack创建了我的Heroku应用程序：https://github.com/heroku/heroku-buildpack-scala
此外，在SBT（或播放配置）中是否有一种精确的方法，在Heroku生产环境中不应下载某些依赖项如Specs2（测试）？

我运行以下命令来显示我在Heroku上推送的实际大小：

获胜者是：227M ./.jdk/jre参与slug大小。这是......正常吗？
答案 0 :(得分：6)
Heroku最近改变了我们使用您的应用程序部署的JDK的方式。它现在比以前大很多。我们还提高了slug大小限制，因此除了使发布版本变慢之外，这不会妨碍你的应用程序。
我们会更新文档以匹配实际的当前限制。
