scala - "Repository for publishing is not specified"尽管发布成功

Question

我的大型 SBT 项目中有一个单独的 Settings.scala 文件，其中包含以下内容:

lazy val commonSettings = Seq(
  // ... lots of settings
  publishTo :=
    Some("Sonatype Nexus Repository Manager" at
      "http://my.company.nexus/content/repositories/releases/"),
  credentials += Credentials(Path.userHome / ".ivy2" / ".credentials"),
  publishMavenStyle := true,
  crossScalaVersions := Seq("2.10.6"),
  // ... lots of other settings
)

现在我在 build.sbt 中的所有项目都定义如下:

lazy val aProject =
  project.in(file("somewhere/aProject")).
    settings(commonSettings).
    settings(
      // project specific settings
    )

当我现在这样做时

sbt "+ publish"

我看到我的所有工件都已发布，当我查看 Nexus 时它们就在那里，而且我还可以将它们用作依赖项等，因此发布有效，但最终我得到以下结果:

我的 sbt 文件中缺少什么/做错了什么？

Answer 1

If a project is not defined for the root directory in the build, sbt creates a default one that aggregates all other projects in the build.

我怀疑您没有定义根项目，因此 SBT 定义了自己的项目，当然它没有获得通用设置。与+ publish SBT 尝试发布它，首先发布它聚合的所有项目(成功)，然后无法发布聚合项目本身。

要解决此问题，可以:

1. 只需定义根项目并显式给出所需的设置(它们不一定相同:实际上没有任何内容可以在那里发布，因此您可能需要 publishArtifact := false )；

2. 进行设置 global :

   publishTo in ThisBuild := ...
