防止 sbt 发布自动聚合的根项目

Question

我有一个 sbt 多项目构建，其中包含两个项目 core 和 mac。我没有聚合它们的根项目。不幸的是sbt does create one automatically。

如何防止发布此虚拟聚合项目？当我运行sbt publish-local 时，除了core 和mac 之外，我得到类似"default-6a1ca6" 的东西。

我正在寻找类似的东西

autoRoot := false

?

Answer 1

对于 sbt 1.x 你也可以使用

lazy val root = (project in file(".")).
    aggregate(core, mac).
    settings(
        skip in publish := true
    )

见https://github.com/sbt/sbt/issues/3136

Answer 2

tl;dr 使用packagedArtifacts in file(".") := Map.empty

使用最新的 SBT 0.13.1 和以下两个文件（项目内没有其他文件）：

build.sbt

lazy val core = project

lazy val mac = project

project/build.properties

sbt.version=0.13.1

...执行sbt publish-local 给出：

$ sbt publish-local

这意味着默认情况下所有项目都已发布。

但是，当您为当前（根）项目添加设置 packagedArtifacts in file(".") := Map.empty 以设置 packagedArtifacts 时：

build.sbt

lazy val core = project

lazy val mac = project

packagedArtifacts in file(".") := Map.empty

...执行sbt publish-local 给出：

$ sbt publish-local
...

没有发布当前（根）项目。

Answer 3

This answer 是一种解决方法：创建一个显式根项目并禁用它的发布。不过，我希望有一个更简单的方法。
