在 sbt 项目中使用来自 Maven Central 的处理库时出现奇怪的错误

Question

我想在 sbt 项目中使用 processing java library，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"

我收到一个错误：

这是什么意思，如何解决？

Answer 1

您没有定义任何解析器。

您可能想尝试将此行添加到您的 build.sbt:

resolvers += Resolver.sonatypeRepo("releases")

或查看此页面以更详细地解释解析器：http://www.scala-sbt.org/0.13/docs/Resolvers.html

Answer 2

尽管 pom 存在，但工件不存在。请参阅 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 poms。我怀疑核心神器可能就是你想要的。

Answer 3

The processing-complete module 只是一个元文件，描述了 processing.org 提供的模块。我原以为 sbt/ivy 能够解析 pom 文件中定义的模块。但是，如果它没有（我没有让 sbt 下载 pom 以外的任何东西），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"

这对我来说很顺利。
