在sbt项目中使用maven中心的处理库时出现奇怪的错误

Question

我试图在一个sbt项目中使用处理java库，所以我在build.sbt中添加了一行:

name := "testJson"
version := "1.0"
scalaVersion := "2.11.7"
//libraryDependencies += "io.spray" %%  "spray-json" % "1.3.2"
libraryDependencies += "org.processing" % "processing-complete" % "3.0b5"

我得到一个错误:

这是什么意思?如何解决?

Answer 1

虽然pom在那里，但是工件却不在。参见http://search.maven.org/#search%7Cga%7C1%7Corg.processing。在这里，您可以看到哪些工件可用于哪些舞会。我怀疑核心工件可能就是你想要的。

Answer 2

您没有定义任何解析器。

您可能想尝试将这行添加到您的build.sbt:

resolvers += Resolver.sonatypeRepo("releases")

或者查看此页面详细解释解析器:http://www.scala-sbt.org/0.13/docs/Resolvers.html

Answer 3

处理完成模块只是一个描述processing.org提供的模块的元文件。我本来期望sbt/ivy能够解析pom文件中定义的模块。但是，如果没有(除了和之外，我没有下载任何其他内容)，我建议您单独添加实际模块:

libraryDependencies += "org.processing" % "core" % "3.0b5"
libraryDependencies += "org.processing" % "net" % "3.0b5"
libraryDependencies += "org.processing" % "video" % "3.0b5"
libraryDependencies += "org.processing" % "serial" % "3.0b5"
libraryDependencies += "org.processing" % "pde" % "3.0b5"
libraryDependencies += "org.processing" % "pdf" % "3.0b5"
