Akka HTTP SBT 模块已解决 ProjectRrf 中跨版本后缀冲突的问题

  • 772

我正在使用 Scala 3 和 SBT 构建一个 Akka HTTP 应用程序，并且它在开始时运行良好。

但是当我添加下面的新依赖项时build.sbt，应用程序开始出现错误 modules were resolved with conflicting cross-version suffixes in ProjectRrf。

新添加的依赖项有：akka-http-circe，，，，，。akka-http-json4sjson4s-nativecirce-genericscala-logging

为了使依赖项与 scala3 兼容，我使用 包装了其中一些.cross(CrossVersion.for3Use2_13)。

导致此错误的原因可能是什么？

提前致谢！

添加的新依赖项：


("com.typesafe.scala-logging" %% "scala-logging"   % "3.9.3").cross(CrossVersion.for3Use2_13),
("de.heikoseeberger" %% "akka-http-circe"          % "1.39.2").cross(CrossVersion.for3Use2_13),
("de.heikoseeberger" %% "akka-http-json4s"         % "1.39.2").cross(CrossVersion.for3Use2_13),
("org.json4s"        %% "json4s-native"            % "4.1.0-M4").cross(CrossVersion.for3Use2_13),
("io.circe"          %% "circe-generic"            % "0.15.0-M1").cross(CrossVersion.for3Use2_13),

构建.sbt：


lazy val akkaHttpVersion = "10.6.3"
lazy val akkaVersion    = "2.9.4"

resolvers += "Akka library repository".at("https://repo.akka.io/maven")

fork := true

lazy val root = (project in file(".")).
  settings(
    inThisBuild(List(
      organization    := "com.example",
      scalaVersion    := "3.3.3"
    )),
    name := "eskimi-bidding-agent",
    libraryDependencies ++= Seq(
      "com.typesafe.akka" %% "akka-http"                % akkaHttpVersion,
      "com.typesafe.akka" %% "akka-http-spray-json"     % akkaHttpVersion,
      "com.typesafe.akka" %% "akka-actor-typed"         % akkaVersion,
      "com.typesafe.akka" %% "akka-stream"              % akkaVersion,
      "com.typesafe.akka" %% "akka-pki"                 % akkaVersion,
      ("com.typesafe.scala-logging" %% "scala-logging"   % "3.9.3").cross(CrossVersion.for3Use2_13),
      ("de.heikoseeberger" %% "akka-http-circe"          % "1.39.2").cross(CrossVersion.for3Use2_13),
      ("de.heikoseeberger" %% "akka-http-json4s"         % "1.39.2").cross(CrossVersion.for3Use2_13),
      ("org.json4s"        %% "json4s-native"            % "4.1.0-M4").cross(CrossVersion.for3Use2_13),
      ("io.circe"          %% "circe-generic"            % "0.15.0-M1").cross(CrossVersion.for3Use2_13),
      "ch.qos.logback"    % "logback-classic"           % "1.2.11",

      "com.typesafe.akka" %% "akka-http-testkit"        % akkaHttpVersion % Test,
      "com.typesafe.akka" %% "akka-actor-testkit-typed" % akkaVersion     % Test,
      "org.scalatest"     %% "scalatest"                % "3.2.12"        % Test

    你没有包含错误最重要的部分。这是

    [error] Modules were resolved with conflicting cross-version suffixes in ProjectRef(uri("file:/path/to/yourproject/"), "root"):
[error]    com.typesafe.akka:akka-http-core _3, _2.13
[error]    com.typesafe.akka:akka-parsing _3, _2.13
[error]    com.typesafe.akka:akka-http _3, _2.13

    因为你写了

    libraryDependencies ++= Seq(
  "com.typesafe.akka" %% "akka-http"                % akkaHttpVersion,
  "com.typesafe.akka" %% "akka-http-spray-json"     % akkaHttpVersion,
  "com.typesafe.akka" %% "akka-actor-typed"         % akkaVersion,
  "com.typesafe.akka" %% "akka-stream"              % akkaVersion,
  "com.typesafe.akka" %% "akka-pki"                 % akkaVersion,

    可能您更喜欢使用_3库的版本而不是_2.13尽可能使用库。

    所以你应该排除

    com.typesafe.akka:akka-http-core _2.13
com.typesafe.akka:akka-parsing _2.13
com.typesafe.akka:akka-http  _2.13

    如果你这样做，sbt dependencyTree你会看到在哪里akka-http-core _2.13使用

    [info]   +-de.heikoseeberger:akka-http-circe_2.13:1.39.2 [S]
[info]   | +-com.typesafe.akka:akka-http_2.13:10.2.7 [S]
[info]   | | +-com.typesafe.akka:akka-http-core_2.13:10.2.7 [S]

[info]   +-de.heikoseeberger:akka-http-json4s_2.13:1.39.2 [S]
[info]   | +-com.typesafe.akka:akka-http_2.13:10.2.7 [S]
[info]   | | +-com.typesafe.akka:akka-http-core_2.13:10.2.7 [S]

    因此使用修改依赖项.exclude(...)

    libraryDependencies ++= Seq(
  ...
  ("de.heikoseeberger" %% "akka-http-circe"          % "1.39.2").cross(CrossVersion.for3Use2_13)
    .exclude("com.typesafe.akka", "akka-http-core_2.13"),
  ("de.heikoseeberger" %% "akka-http-json4s"         % "1.39.2").cross(CrossVersion.for3Use2_13)
    .exclude("com.typesafe.akka", "akka-http-core_2.13"),
  ...

    现在错误是

    [error] Modules were resolved with conflicting cross-version suffixes in ProjectRef(uri("file:/path/to/yourproject/"), "root"):
[error]    com.typesafe.akka:akka-http _3, _2.13

    （可能我们排除的内容也足以排除了akka-parsing _2.13。）

    如果你sbt dependencyTree再做一次，你会看到在哪里akka-http _2.13使用

    [info]   +-de.heikoseeberger:akka-http-circe_2.13:1.39.2 [S]
[info]   | +-com.typesafe.akka:akka-http_2.13:10.2.7 [S]

[info]   +-de.heikoseeberger:akka-http-json4s_2.13:1.39.2 [S]
[info]   | +-com.typesafe.akka:akka-http_2.13:10.2.7 [S]

    再说.exclude(...)一遍

    libraryDependencies ++= Seq(
  ...
  ("com.typesafe.scala-logging" %% "scala-logging"   % "3.9.3").cross(CrossVersion.for3Use2_13),
  ("de.heikoseeberger" %% "akka-http-circe"          % "1.39.2").cross(CrossVersion.for3Use2_13)
    .exclude("com.typesafe.akka", "akka-http-core_2.13")
    .exclude("com.typesafe.akka", "akka-http_2.13"),
  ("de.heikoseeberger" %% "akka-http-json4s"         % "1.39.2").cross(CrossVersion.for3Use2_13)
    .exclude("com.typesafe.akka", "akka-http-core_2.13")
    .exclude("com.typesafe.akka", "akka-http_2.13"),
  ...

    目前项目已经建设成功。

    您也可以将其写为

    libraryDependencies ++= Seq(
  ...
) ++ Seq(
  ("de.heikoseeberger" %% "akka-http-circe"          % "1.39.2").cross(CrossVersion.for3Use2_13),
  ("de.heikoseeberger" %% "akka-http-json4s"         % "1.39.2").cross(CrossVersion.for3Use2_13)
).map(_
  .exclude("com.typesafe.akka", "akka-http-core_2.13")
  .exclude("com.typesafe.akka", "akka-http_2.13")
)

    sbt 1.10.2

  2. 发生该错误的原因是，您具有（传递地）拉取的相同依赖项/工件，但其 Scala 版本后缀不兼容。

    我没有检查你的具体情况，但例如可能是：

    • akka-httpScala 3 拉取XScala 3库
    • akka-http-circe对于 Scala 3 使用 2.13（由于for3Use2_13）并拉取XScala 2.13 的库

    冲突在于该库X被 Scala 3 和 2.13 所撤除。

    您可以通过排除两个版本之一来解决这个问题。但这可能并不总是有效，具体取决于库以及 2.13/3 版本之间是否存在差异/不兼容性。
