java无法将Spring Boot Gradle项目导入Eclipse

4 月 Questions & Answers 1269

我有一个Sprint启动项目，它是在另一个系统上构建的，我正试图将它导入到Eclipse（4.20.0）的一个新系统中，我遇到了一些问题。这是Gradle弹簧靴。我的身材。gradle文件在下面。我已经在机器上安装了JKD 16.0.1——Windows 10

我试着用Gradle buildship和STS插件导入它。当我尝试Buildship时，它在导入预览中失败，出现了一个大堆栈转储，顶行是：

org.gradle.tooling.BuildException: Could not fetch model of type 'GradleBuild' using connection to Gradle distribution 'https://services.gradle.org/distributions/gradle-6.8.3-bin.zip'.

当我尝试Gradle STS时，当我点击“构建模型”按钮时，我告诉我出现了错误，并检查了日志文件。我从中发现了以下有趣的事情：

!ENTRY org.springsource.ide.eclipse.gradle.core 4 0 2021-06-18 17:38:25.575
!MESSAGE Could not determine java version from '16.0.1'.

我还试着在航站楼上建造它，以获得一些线索。这给了我“不支持的类文件主要版本60”错误

Could not compile settings file 'C:\Workspaces\Java\K2\OrderCreate\settings.gradle'.
> startup failed:
  General error during semantic analysis: Unsupported class file major version 60

这看起来真是一团糟。我从哪里开始解决这个问题

plugins {
    id 'org.springframework.boot' version '2.4.5'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
    id 'eclipse'
    id "com.diffplug.eclipse.apt" version "3.29.1"
}

group = 'com.bw'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

repositories {
    mavenCentral()
}

ext {
    mapstructVersion = "1.4.2.Final"
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-artemis'
    implementation 'org.springframework.boot:spring-boot-starter-data-mongodb-reactive'
    implementation 'org.springframework.boot:spring-boot-starter-webflux'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'io.projectreactor:reactor-test'
    
    implementation("org.mapstruct:mapstruct:${mapstructVersion}")
    compileOnly "org.mapstruct:mapstruct-processor:${mapstructVersion}"
    annotationProcessor "org.mapstruct:mapstruct-processor:${mapstructVersion}"
    testAnnotationProcessor "org.mapstruct:mapstruct-processor:${mapstructVersion}"
    
    implementation('org.springframework.boot:spring-boot-starter-data-mongodb')
    testImplementation('de.flapdoodle.embed:de.flapdoodle.embed.mongo')
    implementation 'org.springframework.boot:spring-boot-starter-websocket'
    
    compile group: 'com.google.code.gson', name: 'gson', version: '2.8.5'
}

test {
    useJUnitPlatform()
}

来自Gradle Buildship的错误：
