CreateStartScripts (Gradle API 2.14.1)

Package: org.gradle.jvm.application.tasks

## [Java] Class CreateStartScripts

- org.gradle.jvm.application.tasks.CreateStartScripts

- Creates start scripts for launching JVM applications.

  Example:

       task createStartScripts(type: CreateStartScripts) {
         outputDir = file('build/sample')
         mainClassName = 'org.gradle.test.Main'
         applicationName = 'myApp'
         classpath = files('path/to/some.jar')
       }

  Note: the Gradle `"application"` plugin adds a pre-configured task of this type named `"createStartScripts"`.

  The task generates separate scripts targeted at Microsoft Windows environments and UNIX-like environments (e.g. Linux, Mac OS X). The actual generation is implemented by the getWindowsStartScriptGenerator() and getUnixStartScriptGenerator() properties, of type ScriptGenerator.

  Example:

       task createStartScripts(type: CreateStartScripts) {
         unixStartScriptGenerator = new CustomUnixStartScriptGenerator()
         windowsStartScriptGenerator = new CustomWindowsStartScriptGenerator()
       }

       class CustomUnixStartScriptGenerator implements ScriptGenerator {
         void generateScript(JavaAppStartScriptGenerationDetails details, Writer destination) {
           // implementation
         }
       }

       class CustomWindowsStartScriptGenerator implements ScriptGenerator {
         void generateScript(JavaAppStartScriptGenerationDetails details, Writer destination) {
           // implementation
         }
       }

  The default generators are of the type TemplateBasedScriptGenerator, with default templates. This templates can be changed via the TemplateBasedScriptGenerator.setTemplate method.

  The default implementations used by this task use Groovy's SimpleTemplateEngine to parse the template, with the following variables available:

  - `applicationName`
  - `optsEnvironmentVar`
  - `exitEnvironmentVar`
  - `mainClassName`
  - `defaultJvmOpts`
  - `appNameSystemProperty`
  - `appHomeRelativePath`
  - `classpath`

  Example:

       task createStartScripts(type: CreateStartScripts) {
         unixStartScriptGenerator.template = resources.text.fromFile('customUnixStartScript.txt')
         windowsStartScriptGenerator.template = resources.text.fromFile('customWindowsStartScript.txt')
       }
