finalizing the crowdsale
when the goal is reached
"before each" hook for "handles goal reached":
Error: VM Exception while processing transaction: revert

Problem is in the connection of metamask to the local blockchain by using its RPC address. I use the private key of the first account to get its information. But in my system the first account's actual address in ganache is: 0x4DF4F75E96D49A1b61a4Cd1800d55444bb39C761 but the address that is displayed in my chrome console is 0xED4Cd7eA80CfdDef5c78F6A02C9352124AA6D835. Also in app.js in the render function where I have to display my account I am getting account as NULL. Please do confirm why it is different. How do I wire up the actual account to app.js

Once the people buy the tokens, how does the owner of the contract withdraw the eth back to their own account?

hello i have change the cap and run truffle test is comoing a error:
finalizing the crowdsale
when the goal is reached
"before each" hook for "handles goal reached":
Error: VM Exception while processing transaction: revert.

I have run:

npm install
truffle compile
ganache-cli
truffle deploy

Then when I run:

truffle console
DappToken.deployed().then((instance) => {token=instance})
token.address

This works fine. I get the address.
But when I run:

truffle console
DappTokenCrowdsale.deployed().then((instance) => {crowdsale=instance})

I get the following error:

Error: DappTokenCrowdsale has not been deployed to detected network (network/artifact mismatch)
    at /usr/lib/node_modules/truffle/build/webpack:/packages/truffle-contract/contract.js:454:1

The goalReached function is not defined causing the contract to not be deployable.

because now the current version of solidity is 0.5.x
and also truffle is 5
and openzeppelin-solidity is 2.0

practically watching videos from youtube is useless unless at least you refactor this
repo

i really appreciate your effort

A lot has been changed to openzeppelin-solidity since 1.10.0. Any plan to upgrade this to 2.0.0?
