vespa.ai的SBT依赖项解析失败

Question

我已经将Vespa添加到sbt项目中：

libraryDependencies += "com.yahoo.vespa" % "vespa-http-client" % "6.225.3"

这会导致以下模块解析失败：

[warn]  Detected merged artifact: [FAILED     ] com.yahoo.vespa#component;6.225.3!component.container-plugin:  (0ms).
[warn]  Detected merged artifact: [FAILED     ] com.yahoo.vespa#vespajlib;6.225.3!vespajlib.container-plugin:  (0ms).

旧版本和最新sbt (1.1.1)均失败。

Answer 1

默认情况下，SBT使用工件的打包类型作为文件扩展名。我们的component工件(和很多其他工件)的pom.xml使用打包类型container-plugin，而实际的jar文件当然有标准的jar后缀。

因此，您需要为这些工件手动配置带有文件后缀的SBT。我不知道是否有一种方便的方法可以同时对一组依赖项执行此操作，因为我不是SBT专家。但是对于每个出现此错误的工件，您可以尝试执行以下操作：

libraryDependencies += "com.yahoo.vespa" % "component" % "6.225.3" artifacts( Artifact("component", "", "jar"))

我是在this SO answer中找到的，还没有亲自测试过。也许您可以在Using dependencies with artifacts上的SBT参考手册中找到一些有用的信息。

下面是vespa-http-cient的依赖关系：https://github.com/vespa-engine/vespa/blob/master/vespa-http-client/pom.xml我不太了解SBT，也许你需要显式地包含这些依赖关系，或者指定包含传递依赖关系。
