我尝试安装我的Spring
Boot应用程序。第一步，我尝试按如下所述创建一个可执行jar：https：
//docs.spring.io/spring-boot/docs/current/reference/html/deployment-
install.html

但是，如果我用以下行扩展gradle脚本（我正在使用gradle 4.4）：

springBoot {
    executable = true
}

然后，构建因错误而失败：

FAILURE: Build failed with an exception.

* Where:
Build file 'D:\spring\app\build.gradle' line: 15

* What went wrong:
A problem occurred evaluating root project 'app'.
> Could not find method springBoot() for arguments [build_3mwux4us8m2jn9yfcogqkbm4y$_run_closure1@506b241f] on root project 'app' of type org.gradle.api.Project.

我的构建脚本如下：

buildscript {
    ext {
        springBootVersion = '2.0.0.M6'
    }
    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

springBoot {
    executable = true
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
