(rootProject/*: bintrayEnsureLicenses) vous devez définir au moins une licence pour ce projet

Question

J'essaie de publier mon projet sur bintray pour la première fois. J'ai lu la documentation ici

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

Mon fichier plugins.sbt est

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

Ceci est mon build.sbt. Vous pouvez voir que je l'ai défini la licence pour mon projet

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) 

quand je dis sbt publish je reçois toujours cette erreur

Answer 1

J'ai été capable de résoudre le problème moi-même. Si vous regardez dans le code source du plugin

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

Le type de données de licences est Seq [(String, url)]

Sur la base de ce que j'ai changé mon code en conséquence en faisant les licences comme une séquence de tuples de type (String, url) et le problème a été résolu.

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