[2.0 RC3] One-jar regression?

[Dan Hopkins]

Hey guys,

I had sbt-one-jar setup on 2.0 beta but am now getting an error about loading ehcache.xml.

Anyone have ideas on how to fix this?

A simple way to test is: create a new play project.

Edit the plugins.sbt and add:

resolvers += Resolver.url(

  "sbt-plugin-releases",

  new URL("http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases/")

)(Resolver.ivyStylePatterns)

addSbtPlugin("com.github.retronym" % "sbt-onejar" % "0.7")

libraryDependencies += "commons-lang" % "commons-lang" % "2.6"

Edit Build.scala so that main play project looks like this:

val main = PlayProject(appName, appVersion, appDependencies, mainLang = SCALA,

      settings = standardSettings ++ SbtOneJar.oneJarSettings

    )

Run "play one-jar" and then "java -jar target/scala/2.9.1/YOURAPP.jar"

I get an error like this:

Play server process ID is 41418

Oops, cannot start the server.

net.sf.ehcache.CacheException: Error configuring from jar:file:/emailscorer-application.jar!/lib/play_2.9.1.jar!//ehcache.xml. Initial cause was Error configuring from input stream. Initial cause was null

at play.api.cache.EhCachePlugin.onStart(Cache.scala:127)

at play.api.Play$$anonfun$start$1.apply(Play.scala:60)

I tried baking in the ehcache.xml into the conf directory but it still can't find it.

I know this isn't strictly a play issue but any pointers would be helpful.

Thanks!

Dan

did you eventually get this to work ?

[Dan Hopkins]

I wasn't able to get it to work and ended up switching to a brute force jar strategy. This extracts all the jars, merges them and rejars it.

This is much less optimal because it stomps files with the same name. For right now it's all I have gotten working.

Hi.

you can solve this problem, if your application  doesn't require ehcache,or depends on other cache plugin (ex memcached).

you only need to add a configuraton "ehcacheplugin=disabled"  to  YOUR_APP_DIR/conf/application.conf

My environment

OS    : Amazon Linux AMI (compatible CentOS)

java   : 1.6.0_24

scala : 2.10.0

play   : 2.1.0

application : simple Scala application
