Programmatically create a custom product in Magento 2

Question

I have created a custom product. i.e

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Catalog:etc/product_types.xsd">
 <type name="Dome" label="Event Dome Product" modelInstance="Mymodule\Example\Model\Product\Type\EventDome"
 composite="false" isQty="true" canUseQtyDecimals="false" sortOrder="83">
 <priceModel instance="Mymodule\Example\Model\Product\Type\Price"/>
 <customAttributes>
 <attribute name="refundable" value="true"/>
 <attribute name="is_real_product" value="false"/>
 <attribute name="taxable" value="true"/>
 </customAttributes>
 </type>
</config>

I now want to programmatically create products. The code below is employed on an admin controller page. It works, however, it does not create a fresh product but overrides the previously created product. i.e if I create a product and then try and use the same form to create another one it deletes the previous one.

Also, I am unable to set a price.

$_product = $this->productFactory->create();
 $_product->setName($array['ProductName']);
 $_product->setTypeId('Dome');
 $_product->setAttributeSetId(4);
 $_product->setSku('test-SKU');
 $_product->setWebsiteIds(array(1));
 $_product->setVisibility(4);
 $_product->setPrice(array(350));
 $_product->setStatus(\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED);
 $_product->setStockData(array(
 'use_config_manage_stock' => 0, //'Use config settings' checkbox
 'manage_stock' => 1, //manage stock
 'min_sale_qty' => 1, //Minimum Qty Allowed in Shopping Cart
 'max_sale_qty' => 2, //Maximum Qty Allowed in Shopping Cart
 'is_in_stock' => 1, //Stock Availability
 'qty' => 100 //qty
 )
 );
 $product = $this->productRepository->save($_product);
 $id = $product->getId();
 return $id;

Answer 1

Sorry Everyone. I made a silly mistake. The SKU needs to be unique each time

i,e

$_product->setSku('test-SKU');

Answer 2

Use following code to programmatically create product in magento2.

 $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); // instance of object manager
 $product = $objectManager->create('\Magento\Catalog\Model\Product');
 $product->setSku('sku'); // Set your sku here
 $product->setName('Sample Product'); // Name of Product
 $product->setAttributeSetId(4); // Attribute set id
 $product->setStatus(1); // Status on product enabled/ disabled 1/0
 $product->setWeight(10); // weight of product
 $product->setVisibility(4); // visibilty of product (catalog / search / catalog, search / Not visible individually)
 $product->setTaxClassId(0); // Tax class id
 $product->setTypeId('simple'); // type of product (simple/virtual/downloadable/configurable)
 $product->setPrice(100); // price of product
 $product->setStockData(
 array(
 'use_config_manage_stock' => 0,
 'manage_stock' => 1,
 'is_in_stock' => 1,
 'qty' => 999999999
 )
 );
 $product->save();
 // Adding Image to product
 $imagePath = "sample.jpg"; // path of the image
 $product->addImageToMediaGallery($imagePath, array('image', 'small_image', 'thumbnail'), false, false);
 $product->save();
 // Adding Custom option to product
 $options = array(
 array(
 "sort_order" => 1,
 "title" => "Custom Option 1",
 "price_type" => "fixed",
 "price" => "10",
 "type" => "field",
 "is_require" => 0
 ),
 array(
 "sort_order" => 2,
 "title" => "Custom Option 2",
 "price_type" => "fixed",
 "price" => "20",
 "type" => "field",
 "is_require" => 0
 )
 );
 foreach ($options as $arrayOption) {
 $product->setHasOptions(1);
 $product->getResource()->save($product);
 $option = $objectManager->create('\Magento\Catalog\Model\Product\Option')
 ->setProductId($product->getId())
 ->setStoreId($product->getStoreId())
 ->addData($arrayOption);
 $option->save();
 $product->addOption($option);
 }
