(rootProject/*:bintrayEnsureLicenses) 您必须为此项目定义至少一个许可证

Question

我第一次尝试在 bintray 上发布我的项目。我在这里阅读了文档

https://github.com/sbt/sbt-bintray

我的 plugins.sbt 文件是

addSbtPlugin("org.foundweekends" % "sbt-bintray" % "0.5.1")

这是我的 build.sbt。你可以看到我已经为我的项目定义了许可证

lazy val publishSettings =  Seq(
   licenses += ("MIT", url("http://opensource.org/licenses/MIT")),
   bintrayOrganization := Some("abhishes"),
   bintrayRepository := "AbhiTestRepo",
   bintrayPackageLabels := Seq("foo", "bar")
)

lazy val commonSettings = Seq(
   "organization" := "abhishes",
   version := "1.0",
   scalaVersion := "2.12.3"
)


lazy val project1 = (project in file("SubProject1")).settings(commonSettings)
   .settings(publishSettings)
   .settings(
      name := "SubProject1"
   )

lazy val project2 = (project in file("SubProject2")).settings(commonSettings)
   .settings(publishSettings)
   .settings(
      name := "SubProject2"
   )

lazy val rootProject = (project in file("."))
   .settings(commonSettings)
   .settings(publishSettings)
   .settings(
      name := "MyScalaProject"
).dependsOn(project1, project2)

当我说 sbt publish 时，我仍然收到此错误

编辑：这是inspect licenses的输出

> inspect licenses

Edit2：这是inspect rootProject/licenses的输出

Answer 1

我能够自己解决问题。如果你查看插件的源代码

https://github.com/sbt/sbt-bintray/blob/7a14108bd273a8bb469ad118ccd7cce5b4042099/src/main/scala/Bintray.scala#L33

license的数据类型是Seq[(String, url)]

基于此，我相应地更改了我的代码，将许可证设为(String, url) 类型的元组序列，问题得到了解决。

lazy val publishSettings =  Seq(
   licenses ++= Seq(("MIT", url("http://opensource.org/licenses/MIT"))),
   bintrayOrganization := Some("abhishes"),
   bintrayRepository := "AbhiTestRepo",
   bintrayPackageLabels := Seq("foo", "bar")
)
