我在 IntelliJ IDEA 中有一个 Kotlin 项目（不针对 Android），目前可以使用 Kotlin 1.6.10 正常编译。当我更改为 1.7.10 时，出现以下错误：

FAILURE: Build failed with an exception.

A problem occurred configuring root project \'jwotd\'.

              - Incompatible because this component declares an API of a component and the consumer needed a runtime of a component
          - Variant \'gradle70ApiElements\' capability org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0 declares a component compatible with Java 8, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares an API of a component and the consumer needed a runtime of a component

我的顶级 build.gradle：

buildscript {
    ext.kotlin_version = \'1.7.10\'
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath \"org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version\"
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的一个项目 build.gradle （有几个项目，都相似）：

apply plugin: \'org.jetbrains.kotlin.jvm\'

sourceSets {
    main {
        java.srcDirs \"src/java\"
    }
}

java {
    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8
}

dependencies {
    api project(\':cjk\')
    implementation project(\':kokuban\')
    implementation platform(\'org.jetbrains.kotlin:kotlin-bom\')
    implementation \"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version\"
    implementation \'com.beust:klaxon:5.0.1\' 
    implementation \"com.oracle.database.xml:xmlparserv2:21.1.0.0\"
}

【解决方案1】：

我不得不手动升级gradle。

./gradlew wrapper --gradle-version 7.5.1
./gradlew --version
./gradlew build

之后，gradlew 构建 Kotlin 1.7.10 代码，在 IntelliJ IDEA 中也构建成功。有趣的是，IntelliJ 抱怨不可用的功能（肯定是键入 T 和 Any），但它可以编译它并且它似乎可以工作。

感觉 IntelliJ IDEA CE 还没有正式支持 Kotlin 1.7.10？

【解决方案2】：

这就是新生成的（由 IDEA CE / gradle-7.4.2）build.gradle 的样子

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.7.10'
}

group = 'org.example'
version = '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

dependencies {
    testImplementation 'org.jetbrains.kotlin:kotlin-test'
}

test {
    useJUnitPlatform()
}

compileKotlin {
    kotlinOptions.jvmTarget = '1.8'
}

compileTestKotlin {
    kotlinOptions.jvmTarget = '1.8'
}

【讨论】：

有趣的。所以IDEA CE做支持 kotlin 1.7.10……这是最顶层的 build.gradle 吧？内部项目 build.gradle 是什么样子的？

【解决方案3】：

就我而言，只需替换为

classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.21'

从

classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.10'

【讨论】：

【解决方案4】：

您可以尝试在构建和 gradle 中添加它。

kotlinOptions {
    jvmTarget = "1.8"
}

不幸的是，这并没有解决问题。我还尝试将其包装在compileKotlin 中，或设置languageVersion = 1.7。我仍然得到同样的错误。当我尝试使用./gradlew build 从控制台构建它时，也会出现该错误，因此这不是仅 IDE 的问题。
这不是 .gradle 文件中已添加的解决方案
