Recently I've been assigned for a project created with AngularJs and it uses Java Play framework to run it. I use IntelliJ-Idea IDE for the development and to run this application.

Once I clicked on "Run", it gives me following errors in the console.

```
'force' enabled
Will run: [gulp, --gulpfile=gulpfile.js, watch, --force] in /home/supuns/Projects/bd-business-portal/ui

```

I can't figure out what is happening because I'm new to the environment. 

UPDATE:
Sorry about the less information I have given in my question. I have globally installed gulp but still it is not working.

Here's the content of build.sbt file.

```
name := """bd-business-portal"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayJava)

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  javaJdbc,
  cache,
  javaWs
)

```
