[Adding enchantments to an item when crafted [SOLVED]]

Thank you!! The_SlayerMC's method worked

[Adding enchantments to an item when crafted [SOLVED]]

I created a sword and I wanted it to permanently have a Sharpness enchantment(like in the twilight forest mod) Initially I used this:

public void onCreated(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
    {
    par1ItemStack.addEnchantment(Enchantment.sharpness, 4);

At first everything looked OK but then I realized that if you remove the item from the output slot for the crafting table using shift it doesn't get enchanted Any solutions?

Thank you already downgrading

[Problem at running gradlew.bat]

After learning some java i was ready to start modding Minecraft so i downloaded everything i needed and everything was going perfect until... i went to command prompt to run gradlew.bat setupDecompWorkspace--refresh-dependencies where i got this error.

FAILURE: Build failed with an exception.

 

* What went wrong:

The setupDecompWorkspace will only work with Java 7! This is fixed in ForgeGradle 1.2

 

* Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

 

I am currently using java8 and i understand the error came from there but do i really need to downgrade the java version? Or is there another way?
