scala - 为什么 sbt 不能解决 OpenIMAJ 依赖？

Question

这是我在项目中使用的build.sbt：

name := "FaceReg"

version := "1.0"

libraryDependencies += "org.openimaj" % "image-processing" % "1.2.1"

在updateing 项目时，sbt 报告UNRESOLVED DEPENDENCIES：

[info] Resolving org.openimaj#image-processing;1.2.1 ...
[warn]  module not found: org.openimaj#image-processing;1.2.1
[warn] ==== local: tried

[error] (*:update) sbt.ResolveException: unresolved dependency: org.openimaj#image-processing;1.2.1: not found

可能是什么问题？如何解决？

Answer 1

OpenImaj 有自己的存储库，并且不会将工件发布到 maven 中心（这是 sbt 默认情况下咨询的少数存储库之一）。

添加以下内容resolvers以build.sbt正确解决依赖关系，您会没事的：

resolvers += "OpenIMAJ maven releases repository" at "http://maven.openimaj.org"

resolvers += "OpenIMAJ maven snapshots repository" at "http://snapshots.openimaj.org"

另外，请确保您仅%在工件中使用，而不是%%因为现在看起来您正在依赖特定的 Scala 版本，而这不是您想要的 OpenImaj。
