在Eclipse中设置Akka项目

Question

我正在尝试在Eclipse中创建一个新的Akka项目。我遵循了here的步骤

但是我收到关于找不到Akka依赖项的错误。

会很感谢你的帮助。这是输出。

Answer 1

因此这不起作用(404)：http://repo1.maven.org/maven2/com/typesafe/akka/akka-actor/2.1.2/akka-actor-2.1.2.pom

但这是可行的：http://repo1.maven.org/maven2/com/typesafe/akka/akka-actor_2.10/2.1.2/akka-actor_2.10-2.1.2.pom

查看g8模板(line 16)：

"com.typesafe.akka" % "akka-actor"      % "$akka_version$",

我猜你需要编辑你的project/Build.scala，这样它就会显示：

"com.typesafe.akka" % "akka-actor_2.10"      % "2.1.2",

如果有效的话，请告诉我。
