Question

我必须更新模板文件中的一个变量，所以使用groovy模板引擎进行如下操作：

> def installerTemplate=readFile "${template}" 
>     def binding=[
>             'exeName': exeName
>             ]  
>     def engine=new groovy.text.SimpleTemplateEngine()  
>     def tpl=engine.createTemplate(installerTemplate).make(binding) 
>     writeFile file: "${target}", text: "${tpl}".toString()

但是在这里，我得到了以下权限错误！我在这里看到了类似的问题，但大多数地方解决方案是更改Jenkins安全配置，但在我的情况下，这不是选项。所以有没有其他方法可以解决这个问题，而无需触及Jenkins配置。

或者如果你可以在groovy中建议一些其他方法而不是使用模板！

非常感谢任何建议

谢谢， Ganesh

Answer 1

使用许多签名需要确认并添加到白页，SimpleTemplateEngine也属于它们; 我有一项任务要做你需要的事情;
这就是我得到的：

private static Object binding1(Map map, String string) {
    Template template = new StreamingTemplateEngine().createTemplate(string)
    return template.make(map.withDefault { "&lt;not found&gt;" })
}

但是，由于您没有jenkins的管理员权限，您可以实现以下内容：

private static Object binding2(Map map, String string) {
    for (def data : map) {
        string = string.replace("\${" + data.getKey() + "}", data.getValue().toString())
    }
    return string
}

希望它有所帮助。
