Heroku Slug大小为222 MB/Play Framework 2.1 /

Question

我在Heroku上的app slug大小表示222 MB.相当巨大,超过200MB允许.

因此,我检查过这些事情:

• 检查我的源代码大小:89,9知道80,2M来自玩app的目标文件夹.

• 检查我的.gitignore文件,以确保排除播放应用程序的目标文件夹.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

这里详细介绍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:

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.neo4j" % "neo4j-rest-graphdb" % "1.9.M04",
     "org.scalaz" %% "scalaz-core" % "7.0-SNAPSHOT" withSources(),

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

我该怎么做才能减少这个巨大的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.

它似乎真的发送了应用程序的目标文件夹..尽管.gitignore文件

当然,我使用这个buildpack创建了我的Heroku应用程序:https://github.com/heroku/heroku-buildpack-scala

此外,有没有一种方法可以精确地在SBT(或播放配置)中,某些依赖项如Specs2(测试)不应该在Heroku生产环境中下载？

在压缩之前375 Mo我想象最终会达到222Mo ..哼

获胜者是:227M ./.jdk/jre 参与slug尺寸.这是......正常吗？

Answer 1

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,这不会妨碍您的应用程序.

我们将更新文档以匹配实际的当前限制.
