我可以说在科特林

//sweet
for ((key,value) in System.getProperties())
    println("$key = $value")

但我不能说

//sour
val properties = System.getProperties()
val list = properties.map((key,value) -> "$key = $value")

什么是Scot中的Kotlin等价物properties.map{case (key, value) => s"$key = $value"}？

我试图通过Javascript(查询控制台)将一些三元组插入到表单的JSON文档中

declareUpdate();
xdmp.documentInsert('/aem/5/content/demo-spark/en_GB/automation_article.json',
{
  "triple" : {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/author",
    "object" : "jasonmoore"
  },
  "triple" : {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/id",
    "object" : "automation_article2"
  },
  "triple" : {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/dateCreated",
    "object" : "2015-08-14 09:38:10 GMT-7:00"
  },
  "content" : {
  . . .
  }
});

但是,当我查看新创建的文档时,只有最后一个三元组,其他两个缺失.

我需要做什么才能在同一份文件中获得前两个三元组？

将项目移动到 C: 上的本地文件系统后，现在我得到了

我试图让 Maven 编译 Scala 3，但我得到了奇怪的东西，比如

首先，为什么.java文件也会失败？ …
