Question

我正在使用gradle和spring boot创建我的第一个spring项目。我想从netbeans中的数据库创建实体类。当我尝试执行此操作时，单击“完成”按钮后，出现以下错误：

我的build.gradle看起来像这样：

import org.gradle.api.artifacts.*


buildscript {
    repositories {
        mavenCentral()
        maven{
            url 'https://repo.spring.io/libs-release'
        }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.3.RELEASE")
    }
}

apply plugin: 'base' // To add "clean" task to the root project.
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

bootJar {
    mainClassName='org.gogogold.core.Skelton.xuyun'
    baseName = 'gradlePom'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

dependencies {

    compile("org.springframework.boot:spring-boot-starter")
    compile("org.springframework.boot:spring-boot-starter-data-jpa")
    compile("org.springframework.data:spring-data-jpa:2.0.8.RELEASE")
    // https://mvnrepository.com/artifact/org.eclipse.persistence/javax.persistence
    compile group: 'org.eclipse.persistence', name: 'javax.persistence', version: '2.2.0'

    // https://mvnrepository.com/artifact/org.hibernate/hibernate-core
    compile group: 'org.hibernate', name: 'hibernate-core', version: '5.3.1.Final'

    compile group: 'org.hibernate.javax.persistence', name: 'hibernate-jpa-2.1-api', version: '1.0.2.Final'

}

我在netbeans中连接了数据库，我尝试用Google搜索答案，但是最相似的问题已针对6.3或更高版本的netbeans解决。我应该怎么做才能使JPA工作？非常感谢你！
