== bootRun

=== Purpose

Runs a Grails application in an embedded servlet container

WARNING: This target is _not_ intended to be used for application deployment. There are many optimizations implemented when  generating a WAR file for deployment that are not available to `bootRun` since `bootRun` is optimized for developer productivity, not performance.

=== Examples

[source,console]
----
$ ./gradlew bootRun
$ ./gradlew bootRun --debug-jvm
$ ./gradlew bootRun -Dgrails.env=test
$ ./gradlew bootRun --args=--server.port=8081
----

=== Description

Usage:

[source,console]
$ ./gradlew bootRun <<gradle-args>> --args=<<*args>>

Gradle Arguments: \<<gradle-args>>

* `--debug-jvm` - Run the application using a debug JVM (port 5005) in order to attach a remote debugger.
* `-Dgrails.env=*env` - The grails environment to use (dev/test/prod)

Additional Arguments <<*args>>:

* `server.port` - The port to use.
For more args, see {springBootHowTo}properties-and-configuration.html#page-title[Spring Boot Application Properties].


This command starts Grails in an embedded servlet container that can serve HTTP requests. The default container is https://tomcat.apache.org[Tomcat] but alternative containers are supported by altering the Spring boot starter in `build.gradle`.

[source,groovy]
.build.gradle
----
// use Jetty
runtimeOnly "org.springframework.boot:spring-boot-starter-jetty"

For more information see the Spring Boot documentation on {springBootHowTo}webserver.html#page-title[Embedded Containers].
