vespa.ai的SBT依赖关系解析失败

Question

I've added Vespa to an sbt project:

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

Which results in the following module resolution failure:

[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).

Failed with both an older version and latest sbt (1.1.1).

Answer 1

SBT uses the artifact's packaging type as file extension by default. Our pom.xml for the component artifact (and quite a few others) uses packaging type container-plugin , while the actual jar file of course has the standard jar suffix.

So you need to configure SBT manually with the file suffix for those artifacts. I don't know if there's a convenient way to do this for a set of dependencies at once, as I'm not an SBT expert. But for each individual artifact where you get this error, you could try the following:

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

I found it in this SO answer and haven't tested it myself. Perhaps you can find some useful information in the SBT reference manual on Using dependencies with artifacts .

Answer 2

以下是vespa-http-cient的依赖项： https : //github.com/vespa-engine/vespa/blob/master/vespa-http-client/pom.xml我不太了解SBT，也许您需要明确包含那些依赖关系，或指定包含传递依赖关系。
