在sbt / play-framework中包含/排除资产文件夹/目录

Question

我想在play-framework 2.4.X应用程序中包含一个gulp，angular项目。

有一个node_modules文件夹，其中包含许多文件和文件夹。 SBT在我的构建过程中包含这些文件; 这使我的构建过程非常缓慢。

所以我想排除那些和其他不必要的文件和文件夹。 我的build.sbt文件部分代码

lazy val gulpDirectory = baseDirectory { _ / "admin-panel" }
unmanagedResourceDirectories in Assets <+= gulpDirectory

//includeFilter in Assets in unmanagedResourceDirectories := {
//    new SimpleFileFilter( file =>
//        file.getParent == "bower_components" ||
//                file.getParent == "tmp" ||
//                file.getParent == "dist"
//    )
//}

includeFilter in Assets in unmanagedResourceDirectories := "bower_components" || "dist" || "tmp"
excludeFilter in Assets in unmanagedResourceDirectories := new SimpleFileFilter(_.getParent == "node_modules")

但那些不起作用，SBT包括来自admin-panel文件夹的所有文件和文件夹。 任何人都可以帮助我，因为我是SBT的新手。

我的解决方案是......

build.sbt

import play.sbt.PlayImport.PlayKeys.playRunHooks

lazy val gulpDirectory = baseDirectory {
    _ / "admin-panel"
}

excludeFilter := HiddenFileFilter -- ".tmp"

unmanagedResourceDirectories in Assets <+= gulpDirectory { _ / "dist"}

unmanagedResourceDirectories in Assets <+= gulpDirectory { _ / ".tmp"}

unmanagedResourceDirectories in Assets <+= gulpDirectory { _ / "bower_components"}

//this is for development environment
unmanagedResourceDirectories in Assets <+= gulpDirectory { _ / "src" / "app"}

playRunHooks <+= gulpDirectory.map(path => Gulp(path))

project / Gulp.scala

import play.sbt.PlayRunHook
import sbt._

import java.net.InetSocketAddress

object Gulp {
    def apply(base: File): PlayRunHook = {

        object GulpProcess extends PlayRunHook {

            val gulpFile = "gulpfile.js"
            var process: Option[Process] = None

            override def beforeStarted(): Unit = {
                if (isWindows) {
                    Process("cmd /c gulp build", base).run
                } else {
                    Process("gulp build", base).run
                }
            }

            override def afterStarted(addr: InetSocketAddress): Unit = {
                if (isWindows) {
                    Some(Process("cmd /c gulp serve", base).run)
                } else {
                    Some(Process("gulp serve", base).run)
                }
            }

            override def afterStopped(): Unit = {
                process.map(p => p.destroy())
                process = None
            }

            private def isWindows: Boolean = {
                System.getProperty("os.name").startsWith("Windows")
            }
        }

        GulpProcess
    }
}
