未找到plotply scala sbt未解析的依赖项

我正试图开始有计划地使用scala。我严格遵守他们的指示，但sbt返回一个错误：

maven central上只有

0.1

版本。0.2尚未发布。要使用0.2版本，请更改

build.sbt

文件：

resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"
libraryDependencies += "co.theasi" %% "plotly" % "0.2-SNAPSHOT"

---

build.sbt

中有什么？

resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"
libraryDependencies += "co.theasi" %% "plotly" % "0.2-SNAPSHOT"
