我尝试做一个简单的基于akka的NetLogo扩展。然而,每当我尝试在NetLogo中加载扩展时,我会得到错误:
Caused by: com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'akka.version'
这显然意味着缺少一些配置。然后我继续将reference.conf添加到我的资源文件夹中,但没有运气。
我最后尝试的是使用sbt-assemblty插件,但是我总是得到同样的错误。所以这是我的build。sbt:

我有一个项目/程序集.sbt,其内容为:
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.1")
我有一个程序集.sbt,根目录下有以下内容:
import sbtassembly.AssemblyKeys._
baseAssemblySettings
在我的scala代码中,我有:
val configString = ConfigFactory.parseString(
"""
akka {
loglevel = "INFO"
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
enabled-transports = ["akka.remote.netty.tcp"]
netty.tcp {
hostname = "127.0.0.1"
port = "9500"
}
log-sent-messages = on
log-received-messages = on
}
}
""".stripMargin)
val config = ConfigFactory.load(configString)
resources文件夹中有一个application.conf文件,我现在不使用它,查看jar tf命令的输出和表达式“reference”,可以清楚地看到reference.conf文件的存在:
我如何将这个akka示例打包为netlogo扩展?
注意:我已经包含了akka-actor和akka-remote作为库依赖项。我在OS X平台上使用Intellij和SBT 0.13.8。
编辑:在接受了Ayush的建议后,我从命令sbt汇编中得到了以下输出,但仍然存在相同的异常:

按热度按时间ubbxdtey1#
我认为问题是在使用sbt:assembly时,默认的合并策略排除了所有的reference.conf文件。这是我在文档中发现的。
如果多个文件共享相同的相对路径(例如,多个依赖关系JAR中名为application.conf的资源),则默认策略是验证所有候选文件是否具有相同的内容,否则将出错。
是否可以尝试按如下方式添加合并策略

有一个额外的技巧来解决这个问题,新的akka库,因为akka不包括他们的所有默认配置在resource.conf
