SBT 解析因 Ivy 额外属性而失败

我正在尝试将 Ivy 额外属性与 SBT 一起使用。我有两个模块：foo-model 和 foo-api。对于他们两个，我将其添加到build.sbt:

projectID <<= projectID { id =>
   id extra("branch" -> "master-api-model-separation")
}

Foo-model 正在发布到 Artifactory（通过 sbt 发布）。发布的 POM 文件如下所示：

<?xml version='1.0' encoding='UTF-8'?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://maven.apache.org/POM/4.0.0">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.foo</groupId>
    <artifactId>foo-model</artifactId>
    <packaging>jar</packaging>
    <description>foo-model</description>
    <version>1.0</version>
    <name>foo-model</name>
    <organization>
        <name>com.foo</name>
    </organization>
    <properties>
        <branch>master-api-model-separation</branch>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.scala-lang</groupId>
            <artifactId>scala-library</artifactId>
            <version>2.10.3</version>
        </dependency>
        ...

然后我需要 foo-api 来使用 foo-model，所以我将其添加到其 build.sbt 中：

def appDependencies = Seq(
    "com.foo"%"foo-model"%"1.0" extra( "branch" -> "master-api-model-separation" ) changing(),
    ...

但是，当我尝试运行 SBT（更新或包）时，我得到以下信息：

[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  ::          UNRESOLVED DEPENDENCIES         ::
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::

[warn] 

并且有一个异常和一个错误。我尝试使用 SBT 0.13.0 和 0.13.1。

我没有设法获得更有用的调试输出。我只从最后一个命令得到这个：

[debug]                 tried http://xdctest-app-01:8081/artifactory/foo-master/com/foo/foo-model/1.0/foo-model-1.0.jar

上述URL处的POM文件确实存在，其内容如上所引用，即：它具有值为 master-api-model-separation 的分支属性。

我究竟做错了什么？

Ivy 额外属性可能需要 Ivy 存储库才能工作，如果您使用 Artifactory，这应该可以工作。 sbt 确实在内部使用额外的属性来编码 Maven 存储库上的 Scala 版本，但我不知道这些位是否公开。

这是我用作测试的内容。

构建.sbt

lazy val root = (project in file(".")).
  settings(
    bintrayReleaseOnPublish in ThisBuild := false
  )

val customPattern = "[organisation]/[module]/" +
  "(scala_[scalaVersion]/)(sbt_[sbtVersion]/)(branch_[branch_name]/)" +
  "[revision]/[type]s/[artifact](-[classifier]).[ext]"

lazy val libExtra = (project in file("libExtra")).
  settings(
    version := "0.1",
    scalaVersion := "2.11.7",
    organization := "com.example",
    name := "somelibrary",
    projectID := {
      val previous = projectID.value
      previous.extra("branch_name" -> "master-api-model-separation")
    },
    licenses += ("MIT", url("http://opensource.org/licenses/MIT")),
    bintrayVcsUrl := Some("[email protected] /cdn-cgi/l/email-protection:you/your-repo.git"),
    bintrayOrganization := None,
    bintrayRepository := "test-test-test",
    publishMavenStyle := false,
    checksums in publish := Nil,
    publishTo := {
      Some(URLRepository("test-bintray-ivy", Patterns(
        s"https://api.bintray.com/content/you/${bintrayRepository.value}/" +
        customPattern +
        s";bt_package={normalizedName.value};bt_version={version.value}")))
    }
  )

lazy val app = (project in file("app")).
  settings(
    scalaVersion := "2.11.7",
    organization := "foo",
    libraryDependencies += "com.example" %% "somelibrary" % "0.1" extra("branch_name" -> "master-api-model-separation"),
    resolvers += Resolver.url("test-bintray-ivy", url("https://dl.bintray.com/you/test-test-test/"))(Patterns(
      customPattern)),
    fullResolvers := fullResolvers.value.filterNot(_.name == "inter-project")
  )

一半的设置基本上设置为发布到虚拟 Bintray 存储库以进行测试。以下是一些注意事项：

• 名字branch已被占用，所以我认为您无法使用它。我是苏金branch_name.
• publishTo 包含一个自定义工件模式，其中包含嵌入在 URL 中的额外属性。

Using app我能够从 Bintray 解析 JAR：

app> compile

[info] Resolving jline#jline;2.12.1 ...

未来的改进：这是我尝试使用 Maven 存储库来做到这一点的尝试 -https://gist.github.com/eed3si9n/a6de413b1ced84649ae0 https://gist.github.com/eed3si9n/a6de413b1ced84649ae0
