我有一个包含两个项目core和mac的sbt多项目构建。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"default-6a1ca6"时，除core和mac之外，我会收到sbt publish-local之类的内容。
我正在寻找像
这样的东西autoRoot := false

对于sbt 1.x，您也可以使用
lazy val root = (project in file(".")).
aggregate(core, mac).
settings(
skip in publish := true
)

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（项目中没有其他文件）：
<强> build.sbt
lazy val core = project
lazy val mac = project
<强>项目/ 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：
<强> 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
...
[info] Set current project to root-0__multi (in build file:/Users/jacek/sandbox/so/0__multi/)

没有发布当前（根）项目。
答案 2 :(得分：0)
This answer是一种解决方法：创建一个显式的根项目并禁用它的发布。我希望有一种更简单的方法。
