Change the embedded script default to disabled
Update the Maven and Gradle repackage tasks so that the embedded startup script is no longer included by default. This change is primarily due to the `cf` command line not currently accepting the unusual jar format. Fixes gh-3045

== Installing Spring Boot applications
|
||||
In additional to running Spring Boot applications using `java -jar` it is also possible
|
||||
to execute applications directly on Unix systems (Linux, OSX, FreeBSD etc). This makes it
|
||||
very easy to install and manage Spring Boot applications in common production
|
||||
environments. As long as you are generating '`fully executable`' jars from your build, and
|
||||
you are not using a custom `embeddedLaunchScript`, the following techniques can be used.

|
||||
|
||||
To create a '`fully executable`' jar with Maven use the following plugin configuration:
|
||||
|
||||
[source,xml,indent=0,subs="verbatim,quotes,attributes"]

|
||||
<executable>true</executable>
|
||||
</configuration>
|
||||
</plugin>
|
||||
----
|
||||
|
||||
With Gradle, the equivalent configuration would be:
|
||||
|
||||
[source,groovy,indent=0,subs="verbatim,quotes,attributes"]

----
|
||||
apply plugin: 'spring-boot'
|
||||
|
||||
springBoot {
|
||||
executable = true
|
||||
}
|
||||
----
|
||||
|
||||
NOTE: Fully executable jars work by embedding an extra script at the front of the file.
|
||||
Not all tools currently accept this format so you may not always be able to use this
|
||||
technique.
