无法为gradle项目创建JAR文件

Question

我想创建一个jar文件，我可以上传到AWS，但每次我运行命令'gradle jar'从命令提示符我得到以下错误。

> Task :compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> Compilation failed; see the compiler error output for details.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or -- 
debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

每当我在命令提示符中运行gradle清除时，我都会得到“构建成功”。下面是build.gradle内容：

buildscript {
ext {
    springBootVersion = '2.0.4.RELEASE'
}
repositories {
    mavenCentral()
    maven {
        url "https://plugins.gradle.org/m2/"
    }
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    classpath "net.ltgt.gradle:gradle-apt-plugin:0.18"
}
}



apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'net.ltgt.apt'

group = 'com.myproject.api'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = JavaVersion.VERSION_1_8


ext {
  lombokVersion = '1.16.20'
  mapstructVersion = '1.2.0.Final'
}

repositories {
    mavenCentral()
    mavenLocal()
    jcenter()
             flatDir {
                dirs 'libs'
        }


}

dependencies {

    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.springframework.boot:spring-boot-starter-mail')
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')
    compile('org.springframework.data:spring-data-jpa')
    compile('io.springfox:springfox-swagger2:2.9.2')
    compile('io.springfox:springfox-swagger-ui:2.9.2')
    compile group: 'commons-io', name: 'commons-io', version: '2.6'


    compile group: 'org.json', name: 'json', version: '20180813'
    compile files('libs/checksum_2.0.0.jar')

    compileOnly("org.projectlombok:lombok:${lombokVersion}")
    compileOnly("org.mapstruct:mapstruct-jdk8:${mapstructVersion}")
    compileOnly("org.mapstruct:mapstruct-processor:${mapstructVersion}")

    runtime('org.springframework.boot:spring-boot-devtools')
    runtime('mysql:mysql-connector-java')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}


eclipse {
    classpath {
        file.whenMerged { cp ->
            cp.entries.add( new org.gradle.plugins.ide.eclipse.model.SourceFolder('build/generated/source/apt/ma 
   in', null) )
        }
    }
}

我需要添加插件吗？提前谢谢。请帮忙

Answer 1

打开任务管理器并强制停止Java（TM）平台SE

C:\Users\{current user}\。gradle\caches\jars-9\jars-9。锁定文件

Answer 2

我用的是“gradle clean”和“gradle build”，而不是“gradlew clean”和“gradlew build”。格拉德卢指挥部为我工作。
