Question

我正在编写自定义grails脚本。我想要自定义帮助，选项等。

根据doc（ http://grails.github.io/grails-doc/latest/guide/commandLine.html#creatingCustomScripts），我只需要这样做：

description( "Generates a controller that performs CRUD operations and the associated views" ) {
  usage "grails generate-all [DOMAIN CLASS]"
  flag name:'force', description:"Whether to overwrite existing files"
  argument name:'Domain Class', description:'The name of the domain class'
}

但是，当我将其添加到我的脚本中时，我得到：

Warning: Error caching created help for /server/scripts/ExecuteDBScript.groovy: No signature of method: ExecuteDBScript.description() is applicable for argument types: (java.lang.String, ExecuteDBScript$_run_closure1) values: [Generates a controller that performs CRUD operations and the associated views, ...]

我的脚本如下：

includeTargets << grailsScript("_GrailsInit")


description( "Generates a controller that performs CRUD operations and the associated views" ) {
    usage "grails generate-all [DOMAIN CLASS]"
    flag name:'force', description:"Whether to overwrite existing files"
    argument name:'Domain Class', description:'The name of the domain class'
}
/**
 * Script to execute the DB script.
 *
 */
target(main: "This script executes DB Script") {
...
}

有什么想法吗？

文档很差，但我找到了这个解决方案：

includeTargets << grailsScript("_GrailsBootstrap")

USAGE = """
    grails script-name [PARAM]

where
    PARAM       = Description
"""

target (default: "command description") {
    //...
}

您的链接（http://grails.github.io/grails-doc/latest/guide/commandLine.html#creatingCustomScripts）是指最新版本的grails，一个非稳定版本（3.0.0.M2）。

您可能正在使用最新的稳定版本2.4.4，因此正确的文档位于此处：http://grails.github.io/grails-doc/2.4.4/ref/Command%20Line/create-script.html
