如何通过gradle命令生成jar

Question

美好的一天，

我有一个gradle项目，该项目是由已经离开的资深人士开发的。

当前该项目有一些更改，现在我想向客户端提供最新的jar，但是，当我要生成此jar时，我遇到了一些问题。

这是build.gradle代码：

buildscript {
    ext {
        springBootVersion = '1.3.8.RELEASE'
        poiVersion = '3.15'
        springVersion = '3.0.4.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
    configurations {
        compile.exclude module: "spring-boot-starter-tomcat"
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'spring-boot'

jar {
    baseName = 'c.c.i.converter.statement'
    version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.6
targetCompatibility = 1.6

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


dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    compile("org.springframework.boot:spring-boot-starter-undertow")
    compile("org.springframework.boot:spring-boot-starter-jdbc")
    compile("org.apache.poi:poi:$poiVersion")
    compile("org.apache.poi:poi-ooxml:$poiVersion")
    compile("org.springframework.batch:spring-batch-infrastructure:$springVersion")
    compile("commons-fileupload:commons-fileupload:1.2")
    compile("org.apache.commons:commons-io:1.3.2")

    compile name: 'db2jcc'
    compile name: 'db2jcc_license_cu'

    testCompile('org.springframework.boot:spring-boot-starter-test')
}

processResources {
    exclude('application-db.properties')
}

我尝试了以下命令，但仍然失败：

./gradlew
./gradlew build

这是我得到的错误：

失败：构建失败，并出现异常。

* What went wrong:
A problem occurred configuring root project 'c.c.i.converter.statement'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Could not resolve org.springframework.boot:spring-boot-gradle-plugin:1.3.8.RELEASE.

请告知。
