Question

我有一种传递性的依赖，只是无法解决，我正在撕裂我的头发。

特定的依赖关系是org.apache.maven.wagon#wagon-provider-api;1.0-beta-2!wagon-provider-api.jar，但我不确定哪个直接依赖包含它。

该文件在默认的Maven仓库中运行良好。然而，出于某种原因，SBT只是拒绝检查它，尽管它很乐意在那里查找其他依赖项：

[warn]  [NOT FOUND  ] org.apache.maven.wagon#wagon-provider-api;1.0-beta-2!wagon-provider-api.jar (52ms)

我已从主目录中删除了.ivy2，.m2和.sbt。我跑了sbt update。我一遍又一遍地运行play clean和play clean-all。从SBT提示符运行resolvers显示Maven仓库在列表中。

我已经尝试下载jar并将其添加到我的常春藤缓存，我的Ivy存储库，我的Play！库中。

还有什么可以尝试？

我的Build.scala：

import sbt._
import Keys._
import play.Project._

object ApplicationBuild extends Build {

  val appName         = "conspire"
  val appVersion      = "1.0-SNAPSHOT"

  val appDependencies = Seq(
    // Add your project dependencies here,
    javaCore,
    javaJdbc,
    "mysql" % "mysql-connector-java" % "5.1.18",
    "org.apache.cayenne.plugins" % "maven-cayenne-plugin" % "3.0.2",
    "org.objectstyle.ashwood" % "ashwood" % "2.0",
    "commons-collections" % "commons-collections" % "3.1",
    "commons-lang" % "commons-lang" % "2.6",
    "commons-logging" % "commons-logging" % "1.1"
  )

  val main = play.Project(appName, appVersion, appDependencies).settings(
    externalResolvers += "Local Maven Repository" at "file:///"+Path.userHome+"/.m2/repository",
    resolvers ++= Seq(DefaultMavenRepository,
                      "Objectstyle repository" at " http://objectstyle.org/maven2/")
  )

}

Answer 1

尝试

resolvers := // which overrides current resolvers

而不是

resolvers ++= // which appends to current resolvers

不要问我解释，因为我不知道为什么会这样。刚刚与JUnit有类似的问题，this link建议这样做，这有助于......

Answer 2

而不是：

resolvers :=

（这有不允许多个解析器的缺点。）我找到了

resolvers +=

工作正常，并没有表现出来自OP的错误。

Answer 3

我有类似的问题。但SBT甚至会在maven回购中搜索它所说的不起作用的链接，实际上是有效的。

我通过在默认播放stuf：

之前移动我自己的依赖项来解决它

之前

val appDependencies = Seq(
    // Add your project dependencies here,
    javaCore,
    javaJdbc,
    "mysql" % "mysql-connector-java" % "5.1.32"
  )

<强> AFTER

val appDependencies = Seq(
    "mysql" % "mysql-connector-java" % "5.1.32",
    javaCore,
    javaJdbc    
  )

希望这有助于其他人。干杯

除了Typesafe之外，SBT不会解决对任何存储库的传递依赖性
