groovy - 将命令行参数传递给 Groovy 脚本

Question

我有一个像这样的简单 Groovy 脚本:

class Main {
    static void main(String... args) {
        args.each {
            println ${it}
        }
    }
}

我不知道如何将命令行参数传递给它。我在 Windows 上运行脚本:

Groovy myscript.groovy "arg1" "arg2"

它会导致错误:

Caught: groovy.lang.MissingMethodException: No signature of method: Main$_main_closure1.$() is applicable for argument types: (Main$_main_closure1$_closure2) values: [Main$_main_closure1$_closure2@68b32e3e] Possible solutions: is(java.lang.Object), is(java.lang.Object), any(), any(), any(groovy.lang.Closure), use([Ljava.lang.Object;) groovy.lang.MissingMethodException: No signature of method: Main$_main_closure1.$() is applicable for argument types: (Main$_main_closure1$_closure2) values: [Main$_main_closure1$_closure2@68b32e3e] Possible solutions: is(java.lang.Object), is(java.lang.Object), any(), any(), any(groovy.lang.Closure), use([Ljava.lang.Object;) at Main$_main_closure1.doCall(hash_text.groovy:10) at Main.main(hash_text.groovy:9)

Answer 1

您只是有一个语法错误。而不是

println ${it}

使用

println it

或

println "${it}"
