Cuba添加Scala支持

[tree]

1. 新建一个项目

2. 修改 build.gradle

添加处

就不一一列了，从上往下，对着上面的文件看。

ext.scalaVersion = '2.13.6'

apply(plugin: 'scala')

apply(plugin: 'scala')

compile("org.scala-lang:scala-library:$scalaVersion")
compile("org.scala-lang:scala-compiler:$scalaVersion")
compile("org.scala-lang:scala-reflect:$scalaVersion")

build

3. 在每个子模块项目里添加 scala文件夹

4. 写点Scala代码测试一下

在screens里调用一下试试看

打包测试

。。。竟然成功了？
