gradle构建失败，任务“：compilejava”执行失败

Question

我在一个Java桌面应用程序中使用gradle。

IDE是NetBeans&我想从我的Java类生成一些自动化的JSON。

我实现了3个类（仅POJOs)&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。

然而，gradle并没有解析这些类&也没有下载依赖项。

这是我的gradle档案：

  apply plugin: 'java'

    sourceCompatibility = '1.8'
    [compileJava, compileTestJava]*.options*.encoding = 'UTF-8'

    // NetBeans will automatically add "run" and "debug" tasks relying on the
    // "mainClass" property. You may however define the property prior executing
    // tasks by passing a "-PmainClass=<QUALIFIED_CLASS_NAME>" argument.
    //
    // 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 = ''
    }

    repositories {
        mavenCentral()
        // You may define additional repositories, or even remove "mavenCentral()".
        // Read more about repositories here:
        //   http://www.gradle.org/docs/current/userguide/dependency_management.html#sec:repositories
    }

    dependencies {
        // TODO: Add dependencies here ...
        // You can read more about how to add dependency here:
        //   http://www.gradle.org/docs/current/userguide/dependency_management.html#sec:how_to_declare_your_dependencies

//I also tried compile group: 'com.github.reinert', name: 'jjschema', version: '1.11'

       implementation group: 'com.github.reinert', name: 'jjschema', version: '1.11'
    }

以下是我的POJO，按移动设备顺序排列：

package x_mqtt_message;

import java.util.ArrayList;
import java.util.List;

public class MobileDevice {
    //most likely a phone number tied to the device if available or other id
    private String softwareId; 
    //device's hardwareId, is import if the user changes the phone or swaps SIM cards, we can still identify the hardware for tracking/diagnostics/debugging 
    private String hardwareId; 
    //services running on the device 
    private List<xService> services = new ArrayList<xService>();

    public String getSoftwareId() {
        return softwareId;
    }

    public void setSoftwareId(String softwareId) {
        this.softwareId = softwareId;
    }

    public String getHardwareId() {
        return hardwareId;
    }

    public void setHardwareId(String hardwareId) {
        this.hardwareId = hardwareId;
    }

    public List<xService> getServices() {
        return services;
    }

    public void setServices(List<xService> services) {
        this.services = services;
    }

    }

        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public Object[] getData() {

    private Boolean serviceStatus= false; 

    @Attributes(minItems=0,uniqueItems=true)
    private HashSet<xSensor> listOfSensors = new  HashSet<xSensor>(); 

    public String getServiceName() {
        return serviceName;
    }

    public void setServiceName(String serviceName) {
        this.serviceName = serviceName;
    }

JsonSchemaFactory schemaFactory = new JsonSchemaV4Factory();

JsonNode productSchema = schemaFactory.createSchema(MobileDevice.class);
System.out.println(productSchema);

错误：任务':compilejava'执行失败。

编译失败；有关详细信息，请参阅编译器错误输出。

Answer 1

但是在x_mqtt_message中没有导入JSONSchemafactory。因此编译器找不到这些类。
