我是一个新手我正在使用View - Kotlin跟踪Android房间，并在build.gradle文件上出现以下错误。
Build file 'C:Userssuraj.manjunathAndroidStudioProjectsRoomWordSamplebuild.gradle' line: 3
Could not compile build file 'C:Userssuraj.manjunathAndroidStudioProjectsRoomWordSamplebuild.gradle'.
> startup failed:
build file 'C:Userssuraj.manjunathAndroidStudioProjectsRoomWordSamplebuild.gradle': 3: only id(String), alias(Provider), or alias(ProviderConvertible) method calls allowed in plugins {} script block
这是我的构建。gradle(项目级别)
// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
ext.kotlin_version = '1.5.31'
id 'com.android.application' version '7.3.1' apply false
id 'com.android.library' version '7.3.1' apply false
id 'org.jetbrains.kotlin.android' version '1.7.20' apply false
}
ext {
activityVersion = '1.4.0'
appCompatVersion = '1.4.0'
constraintLayoutVersion = '2.1.2'
coreTestingVersion = '2.1.0'

这是我的构建。Gradle app level
plugins {

我把ext.kotlin_version = '1.5.31'改为id "ext.kotlin_version "version '1.5.31'这将导致错误
* Exception is:
org.gradle.api.plugins.UnknownPluginException: Plugin [id: 'ext.kotlin_version', version: '1.5.31'] was not found in any of the following sources:
- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'ext.kotlin_version:ext.kotlin_version.gradle.plugin:1.5.31')
Searched in the following repositories:
Gradle Central Plugin Repository
Google
MavenRepo
at org.gradle.plugin.use.internal.DefaultPluginRequestApplicator.resolveToFoundResult(DefaultPluginRequestApplicator.java:243)
请帮忙解决这个问题。
你从哪里得到这个设置?模块级build.gradle应该有以下插件块:
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-kapt'
}
项目级应该有这个buildscript(非plugins) block:
buildscript {
ext.kotlin_version = '1.5.31'
...
}
你得到的错误，因为你试图在插件块内定义ext.kotlin_version变量，它是不允许的。如果您遵循链接中的教程，这就是它告诉您如何设置的方法。你也可以查看解决方案仓库的完整项目级和模块级构建文件，如果你想看到完整的设置(只要记住他们使用的是更新的Gradle版本!)
正如cactustictacs所说，kotlin版本应该放在构建中。Gradle项目级文件，它必须放在plugins{}块之前:
buildscript {
ext.kotlin_version = '1.5.31'
......
}
plugins{
.....
}
