如何在多项目构建中使用 sbt 插件作为依赖项？

Question

我有两个 sbt 插件项目，它们都使用多项目构建。我想使用其中一个插件作为另一个插件的依赖项。我能够在单个项目构建中使用它，但是一旦我移动到多项目构建，我似乎无法正确地获得 link 的依赖项。

我的测试插件

build.sbt

lazy val commonSettings = Seq(
    organization := "com.example",
    name := "my-test-plugin",
    version := "0.1.0-SNAPSHOT",
    scalaVersion := "2.10.5"
)

// The contents of root are largely unimportant here
lazy val root = (project in file(".")).settings(commonSettings: _*)

lazy val plugin = (project in file("plugin"))
    .settings(commonSettings: _*)
    .settings(
        sbtPlugin := true
    )

my-test-plugin/plugin/src/main/scala/PluginTest.scala

package com.example.test

// Sample code I would like to access from another plugin
object PluginTest {
    def foo: Unit = println("test")
}

我的子插件

build.sbt

lazy val commonSettings = Seq(
    organization := "com.sample",
    name := "my-sub-plugin",
    version := "0.1.0-SNAPSHOT",
    scalaVersion := "2.10.5"
)

lazy val root = (project in file(".")).settings(commonSettings: _*)

lazy val plugin = (project in file("plugin"))
    .settings(commonSettings: _*)
    .settings(
        sbtPlugin := true,
        libraryDependencies += Defaults.sbtPluginExtra("com.example" % "my-test-plugin" % "0.1.0-SNAPSHOT", "0.13", "2.10")
    ).dependsOn(root)

my-sub-plugin/plugin/src/main/scala/SubPluginTest.scala

package com.sample.test

object SubPluginTest {
    def bar = com.example.test.PluginTest.foo
}

但是最后一个文件没有编译：

[error] /home/mike/code/sbt-tests/my-sub-plugin/plugin/src/main/scala/SubPluginTest.scala:4: object example is not a member of package com
[error]     def bar = com.example.test.PluginTest.foo
[error]                   ^

当我 publish-local 和 plugin/publish-local 这两个项目（更确切地说，只是编译第二个）时，工件正确解析，但 SubPlugintest.scala 无法编译并出现上述错误，就好像依赖性不存在。但是，如果我删除 root 项目并将插件文件放在根目录中（没有惰性 vals 或任何东西，只是一个平面 build.sbt 结构），它就可以工作。

我在这里错过了什么？

我认为这不相关，但我尝试了 0.13.5 和 0.13.8。我也徒劳地尝试在没有 sbtPluginExtra 的情况下添加依赖项，并将它们也放在 plugins.sbt 中（我认为这行不通，但是嘿）。

编辑：

依赖 jar 出现在本地并正确解析：

$ jar tf ~/.ivy2/local/com.example/my-test-plugin/scala_2.10/sbt_0.13/0.1.0-SNAPSHOT/jars/my-test-plugin.jar
META-INF/MANIFEST.MF
com/
com/example/
com/example/test/
com/example/test/PluginTest$.class
com/example/test/PluginTest.class

$ jar tf ~/.ivy2/local/com.example/my-test-plugin_2.10/0.1.0-SNAPSHOT/jars/my-test-plugin_2.10.jar
META-INF/MANIFEST.MF
com/
com/example/
com/example/test/
com/example/test/DummyCode.class
com/example/test/DummyCode$.class

您没有为每个模块设置不同的 name：

我的测试插件

> ;show root/name ;show plugin/name
[info] my-test-plugin
[info] my-test-plugin

我的子插件

> ;show root/name ;show plugin/name
[info] my-sub-plugin
[info] my-sub-plugin

如您所见，在 my-test-plugin 中发布有效：

> ;root/publishLocal ;plugin/publishLocal

但请注意发布路径：

com.example/my-test-plugin_2.10/0.1.0-SNAPSHOT/jars/my-test-plugin_2.10.jar
com.example/my-test-plugin/scala_2.10/sbt_0.13/0.1.0-SNAPSHOT/jars/my-test-plugin.jar

一个名为 my-test-plugin 的非 sbt 插件，为 Scala 2.10 交叉构建。
一个名为 my-test-plugin 的 sbt 插件，为 Scala 2.10 和 sbt 0.13.

这在尝试解析 my-sub-plugin 中的 my-test-plugin 时会产生影响：

[error] Modules were resolved with conflicting cross-version suffixes in {file:/Users/dnw/Desktop/sbt-tests/my-sub-plugin/}root:
[error]    com.example:my-test-plugin <none>, _2.10
java.lang.RuntimeException: Conflicting cross-version suffixes in: com.example:my-test-plugin
    at scala.sys.package$.error(package.scala:27)
    at sbt.ConflictWarning$.processCrossVersioned(ConflictWarning.scala:46)
    at sbt.ConflictWarning$.apply(ConflictWarning.scala:32)

尝试为每个模块指定不同的名称，它应该可以工作。
