java - Kotlin: Unresolved reference :javaClass

Question

我希望有人在构建我的 java/Kotlin 项目时遇到了我遇到的问题。该项目与java和kotlin互操作，有以下版本:

• JDK 1.7
• Kotlin 0.9.66
• Gradle(包装器)2.0

在我进行一些更改(即将一些 java 类转换为等效的 kotlin 版本)之前，Kotlin 一直编译良好。

这是我看到的错误:

  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.

以下是源代码示例:

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没有帮助。

任何帮助将不胜感激!

比较你的脚本和 Kotlin reference关于 Gradle。

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