scala - Heroku Slug 大小为 222 MB/Play Framework 2.1/

Question

我在 Heroku 上的应用程序段码大小为 222 mb。相当大，超出了允许的 200MB。

因此，我检查了这些东西:

检查我的源代码大小: 89,9 莫 知道 80,2 钼 来自玩app的目标文件夹 .

检查我的 .gitignore 文件以确保 Play 应用程序的目标文件夹被排除在外。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 Ivy 缓存大小: 100,9 钼

这里详细介绍了每个文件夹的大小(在左侧):

我的 SBT 构建文件包含以下依赖项:

val appDependencies = Seq(
    jdbc,
    anorm,
    "org.springframework" % "spring-aop" % "3.2.0.RELEASE",
    "org.springframework" % "spring-aspects" % "3.2.0.RELEASE",

      ),
    "org.neo4j" % "neo4j" % "1.9.M05" excludeAll(
        ExclusionRule(organization = "org.neo4j", name="neo4j-kernel")
      ),

     "org.mockito" % "mockito-all" % "1.9.0" %"test",
     "securesocial" %% "securesocial" % "master-SNAPSHOT" withSources()
  )

我能做些什么来减少这个巨大的弹头尺寸？即使我删除了一些文档和 jars 源，大小也会很大。

尽管 .gitignore 似乎真的发送了 Play 应用程序的目标文件夹。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，有没有办法在 SBT(或 Play 配置)中精确，某些依赖项(如 Specs2(测试))不应在 Heroku 生产环境中下载？

压缩前的 375 Mo 我想最终会达到 222Mo .. hum

获胜者是:227M ./.jdk/jre参与slug大小的一部分。这……正常吗？

Answer 1

Heroku 最近改变了我们与您的应用程序一起部署的 JDK 的构建方式。现在它比以前大了很多。我们还提高了 slug 大小限制，因此这不会妨碍您的应用程序，但会使发布速度变慢。

我们将更新文档以匹配当前的实际限制。
