Spring Eclipselink/带渐变的弹簧靴。获取QueryDslPredicateExecutor的ClassNotFoundException

使用以下

gradle

脚本生成的一个简单可执行jar给出了

ClassNotFoundException

group 'com.acme'
version '1.0-SNAPSHOT'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.1.RELEASE")
    }


}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

bootJar {
    baseName = 'acme-project1'
    version =  '0.1.0'
}

jar {
    manifest {
        attributes 'Main-Class': 'com.acme.ApplicationLoader'
        attributes 'Spring-Boot-Classes': 'BOOT-INF/classes/'
        attributes 'Spring-Boot-Lib': 'BOOT-INF/lib/'
    }
}


repositories {
    mavenCentral()
    mavenLocal()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

ext {
    queryDslVersion = '4.1.4'

}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    compile("org.springframework.boot:spring-boot-starter-data-jpa"){
        exclude group: "org.hibernate", module: "hibernate-entitymanager"
    }
    compile("org.springframework.boot:spring-boot-starter-data-rest")

    compile "com.querydsl:querydsl-root:$queryDslVersion"
    compile "com.querydsl:querydsl-jpa:$queryDslVersion"
    compile "com.querydsl:querydsl-apt:$queryDslVersion:jpa"

    compile("com.a:acme-persistence:1.0-SNAPSHOT")

    testCompile("junit:junit")

}

注意：所有

DAO

层代码都打包在一个单独的jar

acme persistence

中，该jar作为

compile（）

依赖项添加

注2：我有另一个项目，它也依赖于

acme持久化

，它是使用maven构建的，运行良好。在取消共享和比较包之后，除了

META-INF/MANIFEST.MF

文件之外，其他所有内容都是相似的。在工作罐中有以下几行：

Spring-Boot-Classes: BOOT-INF/classes/
Spring-Boot-Lib: BOOT-INF/lib/

从gradle建造的罐子里找不到的。因此，我将这些代码添加到gradle项目中，并在取消这些代码行的共享后进行验证。然而，我仍然得到相同的错误

错误：

问题是

spring-data-jpa-1.12.2

had类

querydsldpredicateexecutor

，而在

spring-data-jpa-2.6.0

中它被重命名为

querydspredicateexecutor

注意小的
