尝试访问其他文件时切换至Kotlin DSL未解析的参考 [英] Switching to Kotlin DSL Unresolved reference when trying to access other file

问题描述

我的gradle文件尝试使用Kotlin DSL时出现错误.

I have an error when trying to use Kotlin DSL for my gradle files.

在build.gradle(app)中，我有一个函数可以检索存储在 文件keys.properties，Groovy中的函数如下:

In build.gradle(app) I have a function to retrieve an api key stored in an file keys.properties, the function in Groovy is the following:

// Retrieve key api
def getApiKey() {
    def keysFile = file("keys.properties")
    def keysProperties = new Properties()
    keysProperties.load(new FileInputStream(keysFile))
    def apiKey = keysProperties['API_KEY']
    return apiKey
}

切换到Kotlin DSL时，我天真地更改了功能，如下所示:

When switching to Kotlin DSL I naively changed the function as follow:

// Retrieve key for TMDB api
fun getApiKey() {
    val keysFile = file("keys.properties")
    val keysProperties = Properties()
    keysProperties.load(FileInputStream(keysFile))
    val apiKey = keysProperties["API_KEY"]
    return apiKey
}

该版本然后返回以下错误:

The build then returns the following error:

.../app/build.gradle.kts:13:26: Unresolved reference: Properties

有人知道如何解决这个问题吗?

Does anyone know how to fix that?

，添加一个导入import java.util.Properties解决了问题..但是其他问题来了，请参见此问题

as suggested by #bam bam, adding an import import java.util.Properties solved the problems.. But other problems came, see this question

推荐答案

您是否导入了类?在build.gradle.kts顶部添加import java.util.Properties

did you import class? add import java.util.Properties on top of your build.gradle.kts
