Im using gradle in a Java desktop app.
The IDE is NetBeans & i wanted to generate some automated JSON from my Java classes.
I implemented the 3 classes(just POJOs) & attempted to import 'com.github.reinert', name: 'jjschema', version: '1.11' via gradle.
jjschema will print JSON equivalents of the java objects.
My gradle version is 4.4 & Java C:\Program Files\Java\jdk1.8.0_171 (Both are confirmed by checking the path & issuing cmd commands gradle -version)
C:\X\Documents\NetBeansProjects\xMessage>gradle -version
Gradle 4.4
Build time: 2017-12-06 09:05:06 UTC Revision: cf7821a6f79f8e2a598df21780e3ff7ce8db2b82
Groovy: 2.4.12 Ant: Apache Ant(TM) version 1.9.9 compiled on February 2 2017 JVM: 1.8.0_171 (Oracle Corporation 25.171-b11) OS: Windows 10 10.0 amd64
However gradle is NOT resolving the classes & NOT downloading the dependencies.
Here is my gradle file:
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'
}
Here are my POJO's, in order MobileDevice:
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;
}
class xSensor:
package x_mqtt_message;
import com.github.reinert.jjschema.Attributes;
@Attributes(title="xSensor", description="An external sensor such as ECG,temp,Accelerometer,Pulse-oximete,Barometric Pressure,etc...")
public class xSensor {

private Object [] data;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public Object[] getData() {
return data;
}
public void setData(Object[] data) {
this.data = data;
}
}
class xService:
package x_mqtt_message;
import com.github.reinert.jjschema.Attributes;
import java.util.HashSet;
@Attributes(title="xService", description="A background process that send & receives data via several protocol")
public class xService {
//service examples: mqtt_service, gps_service, compass_service, bluetooth_service, etc...
@Attributes(required=true, description="mqtt_service, gps_service, compass_service, bluetooth_service, etc...")
private String serviceName;
//is the service 100% up & running yes=true no=false

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;
}
}
The main entry:
package x_mqtt_message;
public class x_mqtt_message {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// These packages are NOT being found!!!!
JsonSchemaFactory schemaFactory = new JsonSchemaV4Factory();
schemaFactory.setAutoPutDollarSchema(true);
JsonNode productSchema = schemaFactory.createSchema(MobileDevice.class);
System.out.println(productSchema);
}
}
When build via the IDE im getting:

When I commented out the code in my main class the project builds successfully, therefore there isn't an issue with gradle or java setup, I just cant get the gradle jjschema packages/dependencies to resolve/download via graddle in the project?
Thanks
