Question

我有两个使用多项目构建的sbt插件项目。我想使用其中一个插件作为另一个的依赖。我能够使用单个项目构建来实现这一点，但是一旦我转向多项目构建，我似乎无法正确地链接到依赖项。

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
    )

我的 - 测试 - 插件/插件/ SRC /主/阶/ 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)

我的子插件/插件/ SRC /主/阶/ 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两个项目（而不是仅编译第二个）时，工件会正确解析，但SubPlugintest.scala无法使用上述错误进行编译，就好像依赖项一样不在那里。但是，如果我删除root项目并将插件文件放在root中（没有lazy vals或任何东西，只是一个平坦的build.sbt结构），它就可以工作。

我在这里缺少什么？

我认为它并不相关，但我尝试了0.13.5和0.13.8。我也毫无结果地尝试在没有sbtPluginExtra的情况下添加依赖项，并将它们放在plugins.sbt中（我没想到会有效，但是嘿）。

编辑：

依赖关系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发布工作：

> ;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

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

尝试解决my-test-plugin中的my-sub-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，它应该有效。

如何在多项目构建中使用sbt插件作为依赖项？
