Question

我正在尝试在播放应用程序中生成war文件。

我正在使用starter java项目：play-java-starter-example。在Windows中播放2.6.2版。

我在project / plugins.sbt中添加了插件play2war：

addSbtPlugin("com.github.play2war" % "play2-war-plugin" % "1.4.0")

之后我运行了以下命令：

C:\project_name>sbt
[project_name]$ dist

它会生成一个zip文件。

根据official Doc的下一步是在target / universal / [project_name] / bin

中执行.bat文件

我坚持这一步，执行脚本会给出以下消息： console output

以下是dist命令生成的.bat文件的内容：

Answer 1

我明白了。

以下是步骤：

我在project / plugins.sbt中添加了插件play2war：

addSbtPlugin（“com.github.play2war”％“play2-war-plugin”％“1.4.0”）
添加build.sbt import com.github.play2war.plugin ._

libraryDependencies ++ = Seq（“com.github.play2war”％“play2-war_2.9.1”％“0.8.2”）

Play2WarPlugin.play2WarSettings

Play2WarKeys.servletVersion：=“3.1”

执行命令sbt war

除了生成的战争退出奇怪，它只包含jar文件，这是正常的吗？

从播放应用程序生成战争
