gradle生成失败，任务执行失败'；：编译ejava'；

我在Java桌面应用程序中使用gradle

IDE是NetBeans&我想从Java类中自动生成一些JSON

我实现了3个类（仅仅是pojo）&试图通过gradle导入'com.github.reinert'，名称：'jjschema'，版本：'1.11'

jjschema将打印java对象的JSON等价物

我的gradle版本是4.4和Java C:\Program Files\Java\jdk1.8.0_171（通过检查路径和发出cmd命令gradle-version来确认这两个版本）

C:\X\Documents\NetBeansProjects\xMessage>gradle-版本

---

格拉德尔4.4 构建时间：2017-12-06 09:05:06 UTC 修订：cf7821a6f79f8e2a598df21780e3ff7ce8db2b82

Groovy:2.4.12 Ant:ApacheAnt（TM）版本1.9.9于2017年2月2日编译 JVM:1.8.0_171（Oracle公司25.171-b11） 操作系统：Windows 10.0 amd64

但是gradle没有解析类&没有下载依赖项

这是我的gradle文件：

    //
    // Note however, that you may define your own "run" and "debug" task if you
    // prefer. In this case NetBeans will not add these tasks but you may rely on
    // your own implementation.
    if (!hasProperty('mainClass')) {
        ext.mainClass = ''
    }
