如何将pom xml转换为sbt依赖项？

我有一些项目的所有依赖项都存储在pom.xml文件中

如何从内部检索依赖项，以便轻松地将它们放置到使用sbt的项目中

---

复制粘贴所有这些文件非常耗时。

这个从命令行运行的scala脚本负责将pom.xml文件转换为屏幕上打印的sbt依赖项。然后，只需为每个pom.xml文件复制粘贴一次

注意：pom.xml必须与脚本位于同一文件夹中。然后从命令行执行：

scala scriptname.scala

import scala.xml._

(XML.load("pom.xml") \\ "dependencies") \ "dependency" foreach ((dependency: Node) => {
val groupId = (dependency \ "groupId").text
val artifactId = (dependency \ "artifactId").text
val version = (dependency \ "version").text
val scope = (dependency \ "scope").text
val classifier = (dependency \ "classifier").text
val artifactValName: String = artifactId.replaceAll("[-\\.]", "_")

print("val %s = \"%s\" %% \"%s\" %% \"%s\"".format(artifactValName, groupId, artifactId, version))
scope match {
  case "" => print("\n")
  case _ => print(" %% \"%s\"\n".format(scope))
}
None
});

这解释了一种可能的方法。有一条评论指向一个处理更复杂情况的插件。

我增强了George Pligor的答案（并修复了一些错误），因此创建了一个完整的

build.sbt

文件，其中包含了

pom.xml

中的依赖项。要将Maven

pom.xml

转换为

build.sbt

：

将此代码放入名为

PomToSbt.scala的文件中
pom.xml

键入

scala PomToSbt.scala>build.sbt

将从

pom.xml

中提取依赖项，并将其放入完整的

build.sbt

文件中

代码如下：

import scala.xml._

val lines = (XML.load("pom.xml") \\ "dependencies") \ "dependency" map { dependency => 
  val groupId = (dependency \ "groupId").text
  val artifactId = (dependency \ "artifactId").text
  val version = (dependency \ "version").text
  val scope = (dependency \ "scope").text
  val classifier = (dependency \ "classifier").text
  val artifactValName: String = artifactId.replaceAll("[-\\.]", "_")

  val scope2 = scope match {
    case "" => ""
    case _ => s""" % "$scope""""
  }

  s"""  "$groupId" %% "$artifactId" % "$version"$scope2"""
}

val buildSbt = io.Source.fromURL("https://raw.githubusercontent.com/mslinn/sbtTemplate/master/build.sbt").mkString
val libText = "libraryDependencies ++= Seq("
val buildSbt2 = buildSbt.replace(libText, libText + lines.mkString("\n", ",\n", ""))
println(buildSbt2)

)；如果需要任何更新，我会在那里进行。

迈克，下面是至少适用于Scala 11的代码：

import scala.xml._

//build.sbt file
val lines = (XML.load("pom.xml") \\ "dependencies") \ "dependency" map { dependency =>
  val groupId = (dependency \ "groupId").text
  val artifactId = (dependency \ "artifactId").text
  val version = (dependency \ "version").text
  val scope = (dependency \ "scope").text
  val classifier = (dependency \ "classifier").text
  val artifactValName: String = artifactId.replaceAll("[-\\.]", "_")

  val scope2 = scope match {
    case "" => ""
    case _ => s""" % "$scope""""
  }

  s"""  "$groupId" %% "$artifactId" % "$version"$scope2"""
}

val buildSbt: String = io.Source.fromURL("https://raw.githubusercontent.com/mslinn/sbtTemplate/master/build.sbt").mkString

val libText = "libraryDependencies ++= Seq\\("
val buildSbt2 = buildSbt.replaceFirst(libText, libText + lines.mkString("\n", ",\n", ""))
println(buildSbt2)

@George Pligor我对此做了一些修改，以创建一系列依赖项（添加了我自己的bug）。我制作了Apache2.0，如果有任何评论，请让我知道：）thx！我添加了使用amm传递pom文件参数的可能性：我得到以下错误。scala PomToSbt.scala/root/PomToSbt.scala:14:错误：'；'应为字符串文字，但找到字符串文字。case=>s“”“%”$scope“”^/root/PomToSbt.scala:17:错误：“；”应为字符串文字，但找到字符串文字。s“$groupId”%%“$artifactId”%%“$version”$scope2“^2个错误found@AkshatChaturvedi您可以自由地尝试和编辑答案，以发送一个更好的版本，该版本是最新的，也适用于您和其他STHX！我添加了使用amm传递pom文件参数的可能性：以下是相关链接，对我来说很有用：

import scala.xml._

// 1) Place this code into a file called PomToSbt.scala next to pom.xml
// 2) Type scala PomtoSbt.scala > build.sbt
// The dependencies from pom.xml will be extracted and place into a complete build.sbt file
// Because most pom.xml files only refernence non-Scala dependencies, I did not use %%
