CreateStartScripts (Gradle API 8.11.1)

Package org.gradle.jvm.application.tasks

## Class CreateStartScripts

- java.lang.Object
- - org.gradle.api.internal.AbstractTask
  - - org.gradle.api.DefaultTask
    - - org.gradle.api.internal.ConventionTask
      - - org.gradle.jvm.application.tasks.CreateStartScripts

- All Implemented Interfaces:
    `java.lang.Comparable<Task>`, `org.gradle.api.internal.DynamicObjectAware`, `org.gradle.api.internal.IConventionAware`, `org.gradle.api.internal.TaskInternal`, `Named`, `ExtensionAware`, `Task`, `Configurable<Task>`
  Direct Known Subclasses:
    `CreateStartScripts`

      @DisableCachingByDefault(because="Not worth caching")
      public abstract class CreateStartScripts
      extends org.gradle.api.internal.ConventionTask

  Creates start scripts for launching JVM applications.

  Example:

       task createStartScripts(type: CreateStartScripts) {
         outputDir = file('build/sample')
         mainClass = '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 `"startScripts"`.

  The task generates separate scripts targeted at Microsoft Windows environments and UNIX-like environments (e.g. Linux, macOS). 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(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`
  - `mainModule`
  - `mainClass`
  - `executableDir`
  - `defaultJvmOpts`
  - `appNameSystemProperty`
  - `appHomeRelativePath`
  - `classpath`

  Example:

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