我怎么可以将pom xml转换为sbt依赖关系？

Question

我有一些项目，所有的依赖关系存储在pom.xml文件。

如何从内部检索依赖关系，以便我可以轻松地将它们放到使用sbt的项目中？

复制粘贴他们都只是费时..

Answer 1

此阶脚本，从命令行运行，需要照顾的是，转换pom.xml文件到SBT显示在屏幕上的依赖关系。然后，您只需要为每个pom.xml文件复制一次粘贴。

注意：pom.xml必须与脚本位于同一文件夹中。然后，在命令行你执行：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blog entry解释了一种可能的方式。有一条评论指向处理更复杂情况的插件。

我已经增强了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，该文件包含来自pom.xml的依赖项。要转换一个Maven pom.xml到build.sbt：

1. 将此代码到一个名为下一PomToSbt.scala文件pom.xml
2. 类型scala PomToSbt.scala > build.sbt
3. 从pom.xml的依赖将被提取并放置到一个完整的build.sbt文件。

下面是代码：

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) 

I made a gist;如果需要更新，我会让他们在那里。

迈克，这里至少有11 Scala的工作代码：我需要添加 `进口scala.xml._` 使用Scala

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)

import scala.xml._ 
// To convert a Maven pom.xml to build.sbt: 
// 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 %% 
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)
