Kotlin：未解决的参考：javaClass
我希望有人遇到了我在构建我的java / Kotlin项目时遇到的问题。 该项目与java和kotlin互操作，具有以下版本：
- Jdk 1.7
- Kotlin 0.9.66
- Gradle（包装）2.0
Kotlin已经编译好之前，我做了一些改变，即转换几个Java类到相当于kotlin版本。
这里是我看到的错误：
c:\projects\myproject>gradlew :java:workspace:models:compileKotlin --stacktrace :java:workspace:models:compileKotlin w: Annotations path entry points to a non-existent location: C:\projects\myproject\java\workspace\models\annotations e: C:\projects\CustomerProfileEmail.kt: (15, 32): Unresolved reference: toLowerCase e: C:\projects\CustomerProfilePhone.kt: (34, 22): Unresolved reference: equalsIgnoreCase e: C:\projects\Account.kt: (17, 21): Unresolved reference: javaClass e: C:\projects\Account.kt: (18, 21): Unresolved reference: javaClass e: C:\projects\Account.kt: (31, 15): Unresolved reference: indexOf e: C:\projects\Account.kt: (35, 15): Expression 'length' of type 'kotlin.Int' cannot be invoked as a function.

Gradle脚本
repositories { mavenCentral() } buildscript { repositories { mavenCentral() } dependencies { classpath 'com.connorgarvey.gradle:gradle-grails-wrapper:1.0' classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:0.9.66' classpath 'org.jetbrains.kotlin:kotlin-stdlib:0.9.66' } } apply from: 'build/includes.gradle'
我已经看到这个： https ： //devnet.jetbrains.net/message/5478050没有帮助。
任何帮助将不胜感激！
比较你的脚本与关于Gradle的Kotlin 参考 。
Kotlin Stdlib依赖应该在另一个范围内，而不是buildscript 。 Kotlin插件也应该使用apply plugin来apply plugin 。
