CreateStartScripts - Gradle DSL Version 2.14.1

# CreateStartScripts

API Documentation: | `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 `CreateStartScripts.getWindowsStartScriptGenerator()` and `CreateStartScripts.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(org.gradle.api.resources.TextResource)` 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')
    }

### Properties

`optsEnvironmentVar` | The environment variable to use to provide additional options to the JVM.
`outputDir` | The directory to write the scripts into.
`unixStartScriptGenerator` | Incubating The UNIX-like start script generator.
`windowsStartScriptGenerator` | Incubating The Windows start script generator.
