Add dependence of the project into my custom gradle plugin - gradle

Question

I'm new in the Gradle world and I'm writing a personal plugin for executing the operation on the database, an example:
create a database, delete the database, create a table e insert a value into database, but I have a problem with import dependence for the project that uses my plugin, an example for creating a database using a JDBC I have to need the driver JDBC for the database, this driver is content into project main.
My question is: How getting a dependency jar for the database into my Gradle plugin?
This is my code
package io.vincentpalazzo.gradledatabase.task;
import io.vincentpalazzo.gradledatabase.exstension.GradleDatabaseExstension;
import io.vincentpalazzo.gradledatabase.persistence.DataSurce;
import org.gradle.api.DefaultTask;
import org.gradle.api.artifacts.Configuration;
import org.gradle.api.tasks.TaskAction;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLClassLoader;
import java.util.Iterator;
import java.io.File;
import java.util.Set;
/**

public class CreateDatabaseTask extends DefaultTask {
#TaskAction
public void createAction() {
GradleDatabaseExstension project = getProject().getExtensions().findByType(GradleDatabaseExstension.class);
String url = project.getUrl();
String driverClass = project.getDriver(); //The drive name database is different
String username = project.getUsername();
String password = project.getPassword();
String nameDatabase = project.getNameDatabase();
String nameJar = project.getNameJar();
if (findDependecyFileJarForDriver(nameJar)) {
System.out.println("Jar findend");
} else {
System.out.println("Jar not found");
}
DataSurce dataSource = new DataSurce();
if (dataSource.connectionDatabase(driverClass, url, username, password)) {
if (dataSource.createDatabese(nameDatabase)) {
System.out.println("Database " + nameDatabase + " created");
}
}
}
private boolean findDependecyFileJarForDriver(String nameJar) {
if (nameJar == null || nameJar.isEmpty()) {
throw new IllegalArgumentException("The input parameter is null");
}
Iterator<Configuration> iterable = getProject().getConfigurations().iterator();
boolean finded = false;
while ((!finded) || (iterable.hasNext())) {
Configuration configuration = iterable.next();
Set<File> filesSet = configuration.resolve();
for (File file : filesSet) {
String nameFile = file.getName();
if (nameFile.contains(nameJar)) {
//Now?;
finded = true;
}
}
}
return finded;
}
}
And this is my project and this is the referend for my post on Gradle forum
Sorry for my terrible English but I'm learning

I want to add the answer to this post.
The better solution I found is using this plugin
I used the plugin inside the my code, this is an example
public abstract class AbstractTaskGradleDatabase extends DefaultTask {
protected JarHelper jarHelper;
protected Optional<File> jar;
protected void init(){
jarHelper = new JarHelper(getProject());
jar = jarHelper.fetch("nameDependence");
}
}
inside the builld.gradle
dependencies {
implementation gradleApi()
implementation 'com.lingocoder:jarexec.plugin:0.3'
}
ps: the answer can be changed in the time because the version of the plugin is an beta
