为什么sbt不能解决OpenIMAJ依赖？

Question

下面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update执行项目时，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

有什么问题吗？如何解决这个问题？

Answer 1

OpenImaj有自己的存储库并没有将工件发布到maven中心(默认情况下，这是sbt查阅的为数不多的存储库之一)。

将下面的resolvers添加到build.sbt以使依赖关系得到正确的解决，您就可以了：

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

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

另外，要确保只在工件中使用%，而不是%%，因为现在看来，在依赖项中使用的是特定的Scala版本，而这并不是OpenImaj所希望的。
