Question

我正在使用Java编写Play 2.3.2应用程序。

我已经分发了邮件chimp java api wrapper repository，我已经扩展了它并用2.0.1.2-beta更改了模块版本。

我已将模块安装到本地maven存储库中。然后，我试图从我的Play应用程序的构建中引用它，但是play shell（update）中的activator update命令给出了以下错误：

[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

这是我的副本build.sbt文件的一部分：

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？

Answer 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，因为它告诉我：

[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]     sonatype-snapshots: no ivy file found for com.ecwid#ecwid-mailchimp;2.0.1.2-beta

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

我认为$HOME已经解决，因此问题就解决了。

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：

如果您将其添加为本地Maven存储库，它可以搜索您的本地Maven存储库存储库：
resolvers += "Local Maven Repository" at "file://"+Path.userHome.absolutePath+"/.m2/repository"
或，为方便起见：
resolvers += Resolver.mavenLocal

使用以下build.sbt：

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

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

update停滞无法解决com.ecwid#ecwid-mailchimp;2.0.1.2-beta另一个问题：

为什么激活器无法解析本地maven存储库中的自定义依赖关系？
