如何创建WAR而不是JAR？

Question

我想通过sbt编译成WAR文件，而不是JAR文件，我遵循了这个指南。

我已将build.sbt更改为：

libraryDependencies ++= Seq(
  "org.http4s" %% "http4s-jetty" % Http4sVersion,
  "org.http4s" %% "http4s-jetty-client" % Http4sVersion,
  "org.http4s" %% "http4s-circe" % Http4sVersion,
  "org.http4s" %% "http4s-dsl" % Http4sVersion,
  "io.circe" %% "circe-generic" % CirceVersion,
  "org.specs2" %% "specs2-core" % Specs2Version % "test",
  "ch.qos.logback" % "logback-classic" % LogbackVersion
),
addCompilerPlugin("org.typelevel" %% "kind-projector" % "0.10.3"),
addCompilerPlugin("com.olegpy" %% "better-monadic-for" % "0.3.1"),
// disable .jar publishing
Compile / packageBin / publishArtifact := false,

// create an Artifact for publishing the .war file
Compile / packageWar / artifact := {
  val prev: Artifact = (Compile / packageWar / artifact).value
  prev.withType("war").withExtension("war")
},

// add the .war file to what gets published
addArtifact(Compile / packageWar / artifact, packageWar),
)

“汇编”抱怨道：

/home/developer/scala/user-svc/build.sbt:27: error: not found: value packageWar
Compile / packageWar / artifact := {
^
/home/developer/scala/user-svc/build.sbt:28: error: not found: value packageWar
val prev: Artifact = (Compile / packageWar / artifact).value
^
/home/developer/scala/user-svc/build.sbt:33: error: not found: value packageWar
addArtifact(Compile / packageWar / artifact, packageWar),
^
/home/developer/scala/user-svc/build.sbt:33: error: not found: value packageWar
addArtifact(Compile / packageWar / artifact, packageWar),

我做错了什么？

文档中有一个错误-请参阅https://github.com/sbt/sbt/issues/4490

尝试使用专用的sbt插件- xsbt-web插件 -而不是阅读该网站。根据当前文档，您需要添加到project/plugins.sbt中

addSbtPlugin("com.earldouglas" % "xsbt-web-plugin" % "4.2.0")

然后在build.sbt中启用插件，例如Jetty

enablePlugins(JettyPlugin)

然后可以使用package命令构建WAR。
