Kotlin: 未解决的引用：javaClass

希望有人能够遇到我在构建java/Kotlin项目时遇到的问题。该项目是Java和Kotlin相互操作，具有以下版本：

Jdk 1.7
Kotlin 0.9.66
Gradle (wrapper) 2.0

在我进行一些更改之前，Kotlin编译良好，例如将一些Java类转换为等效的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

:java:workspace:models:compileKotlin FAILED

FAILURE: Build failed with an exception.

这里是源代码的一个例子：

import javax.xml.bind.annotation.*

XmlAccessorType(XmlAccessType.FIELD)
XmlType
XmlSeeAlso(javaClass<LoyaltyCredit>(), javaClass<Debit>())
public open class Transaction: TransactionParent(){
    public var account: Account? = null
    public var balances: Balances? = null
    public var rewards: Rewards? = null
}

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'

我已经看过这个：https://devnet.jetbrains.net/message/5478050，但没有帮助。

非常感谢任何帮助！

将您的脚本与Kotlin有关Gradle的参考进行比较。

Kotlin Stdlib依赖项应该在另一个范围内，而不是buildscript。此外，应该使用apply plugin来应用Kotlin插件。
