为什么激活器无法解析本地 maven 存储库中的自定义依赖项？答案

【问题标题】：Why can't activator resolve a custom dependency in local maven repository?为什么激活器无法解析本地 maven 存储库中的自定义依赖项？

【问题描述】：

我正在使用 Java 编写一个 Play 2.3.2 应用程序。

我已经分叉了邮件黑猩猩 java api 包装存储库，我已经对其进行了扩展并使用 2.0.1.2-beta 更改了模块版本。

我已将我的模块安装到本地 maven 存储库中。然后，我尝试从我的 Play 应用程序的构建中引用它，但是 play shell (activator update) 中的 update 命令给了我以下错误：

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

...

[error] (*:update) sbt.ResolveException: unresolved dependency: com.ecwid#ecwid-mailchimp;2.0.1.2-beta: several problems occurred while resolving dependency: com.ecwid#ecwid-mailchimp;2.0.1.2-beta {compile=[default(compile)]}:
[error]     URI has an authority component
[error]     URI has an authority component

这是我的相关人员在build.sbt 文件中的一部分：

resolvers ++= Seq(
    Resolver.sonatypeRepo("snapshots"),
    "Local Play Repository" at "file://$HOME/.ivy2/local",
    "Local Maven Repository" at "file://$HOME/.m2/repository"
)

libraryDependencies ++= Seq(
    "com.ecwid" % "ecwid-mailchimp" % "2.0.1.2-beta"
)

怎么了？？

【解决方案1】：

当您遇到错误时，sbt 会告诉您运行 last *:update 以查看完整输出：

[trace] Stack trace suppressed: run last *:update for the full output.

在复制案例时，我发现 last *:update 非常有用，因为它向我展示了：

[debug] CLIENT ERROR: Not Found url=https://oss.sonatype.org/content/repositories/snapshots/com/ecwid/ecwid-mailchimp/2.0.1.2-beta/ecwid-mailchimp-2.0.1.2-beta.pom

[debug] problem occurred while resolving dependency: com.ecwid#ecwid-mailchimp;2.0.1.2-beta {compile=[default(compile)]} with Local Play Repository: java.lang.IllegalArgumentException: URI has an authority component

[debug]     at sbt.IO$.toFile(IO.scala:76)
[debug]     at sbt.ConvertResolver$LocalIfFileRepo.getResource(ConvertResolver.scala:222)

我不认为$HOME 已经解决，因此问题。

删除"Local Play Repository" at "file://$HOME/.ivy2/local" 并重新开始。它默认包含在内，您不需要在构建中明确地使用它。

您应该使用Path.userHome.absolutePath 而不是$HOME，如Resolvers 中所述：

sbt 可以搜索你的本地 Maven 存储库，如果你将它添加为仓库：
resolvers += "Local Maven Repository" at "file://"+Path.userHome.absolutePath+"/.m2/repository"
或者，为方便起见：
resolvers += Resolver.mavenLocal

以下build.sbt：

resolvers ++= Seq(
    Resolver.sonatypeRepo("snapshots"),
    Resolver.mavenLocal
)

libraryDependencies ++= Seq(
    "com.ecwid" % "ecwid-mailchimp" % "2.0.1.2-beta"
)

update 停滞不前，无法解决 com.ecwid#ecwid-mailchimp;2.0.1.2-beta 这是另一个问题：
