凹槽中的变量如何通过变量类型设置条件

Question

我是个新手，正在寻求一些建议。 如何在凹槽中创建条件，以便如果变量是字符串，则执行一个动作，如果工作表是另一个动作 就像必须做的那样，如果变量等于 0，那么什么都不会传输

 //aditionalArgs= "test1 = add1 , tets2= add2 "
aditionalArgs = ["test1=arg1", "test2=arg2"]
println(aditionalArgs.class)

def args = ""

if ((aditionalArgs != "class java.lang.String" ) || (aditionalArgs > 0)){
 def list = aditionalArgs.replace("--build-arg", "").split(',')
  list.each { val->
      args += " --build-arg $val"
  }
  
  println(args.replace("",""))
}

if (aditionalArgs == "ArrayList" ){
 def list = aditionalArgs("--build-arg", "").split('[' , ']')
 list.each { val-> 
     args += " --build-arg $val"
}

  println(args.replace("",""))
}

else(aditionalArgs.length() > 0){
  println "empty aditionalArgs"
}```

if (aditionalArgs instanceof String){...}

//is instance of List or anything inherited from List (including ArrayList)
if (aditionalArgs instanceof List){...}

//with full class name
if (aditionalArgs instanceof java.util.ArrayList){...}
