The Remix editor with the error
Can someone help me go past this error? Why does the contract not compiling?
I am able to deploy the source on my machine, just restart the browser and clean the cache and everything then it should work.

I'm trying to migrate my new truffle configs to test a smartcontract in a private network. But when I try to migrate it, I get stuck here:
1_initial_migration.js gets hanging on "Replacing Migrations" forever
Can somebody please help me solving it?
I think I've had this problem. I suspect Ganache is in a bad state. And I swear truffle doesn't incrementally build correctly sometimes. So when in doubt, fully restart Ganache, rebuild with --all and redeploy with --reset .
That is:
Exit Ganche
Check Task Manager, ps, or equivalent and terminate all rogue instances of Ganache that might still be running. Ganache tends to start several child processes. So make sure they aren't lingering around before you restart it.
Restart Ganache with a new workspace.
Recompile with this: truffle compile --all
Redeploy with: truffle deploy --reset
Weird bugs tend to go away when I completely do a full reset as described by these steps. In on case, I just rebooted because port 7575 was locked by something.
I'm faced with issue, can't verify contract after deploy.
Maybe some one has the same issue?

I'm trying to run the Web3j example available at https://github.com/web3j/sample-project-gradle
Unfortunately, there is hardly any information available on how to build and run the example, and newbies have to contend with learning Gradle in addition to the Web3j-Java interface.
I'm able to build the example (after creating a Wallet account with a JSON file, loading it with Rinkleby Ether and inserting my Infura API key into the Application file) as follows:
$ gradle build
which succeeds without errors. However, I am clueless on how to run the project...thanks in advance for any help.

Everything seems ok with the your project. Have you tried "Run as a Java application" option from the Eclipse IDE? I am running my Java smart contract functions in this way.
I'm a DAPP beginner, and am trying to get up and running with the Truffle framework. I've been walking through the Truffle docs, but it doesn't work out of the box for me.
Create directory, cd into it, and run 'truffle init'
Run 'truffle compile'
Run testrpc in a second terminal window, same project directory
Run 'truffle migrate'
This is the error I get from truffle:
Running migration: 1_initial_migration.js
Deploying Migrations...
Error encountered, bailing. Network state unknown. Review successful transactions manually.
Error: Server error
at Object.module.exports.InvalidResponse (/usr/local/lib/node_modules/truffle/node_modules/ether-pudding/node_modules/web3/lib/web3/errors.js:35:16)
at /usr/local/lib/node_modules/truffle/node_modules/ether-pudding/node_modules/web3/lib/web3/requestmanager.js:86:36
I get this with Node v5 & v6.
Truffle v2.1.1.
Web3 and ether-pudding are installed as truffle dependencies.
TestRPC/0.8.7/darwin/python2.7.12.
Thanks for the help-
Are you sure you did run testrpc in a second window and let it run? This is important as testrpc in that case is yoir blockchain. If it does not run you will get similar errors as what you describe.
To keep it simple, I also suggest as a start that you do not run another client while running testrpc (geth, parity, mist, ... )
So in short, do a reboot, start testrpc, make sure it does not display errors, then run the truffle migrate command while testrpc still runs in the background.
Truffle migrate does run correctly. I've reposted my issue with testrpc here:
Testrpc error: 'no loggers could be found for logger 'jsonrpc.manager'
I trying out Ethereum for the first time. I was able to get Ethereum wallet downloaded and installed on my Windows 10 system. Now when I try to launch .exe file I get "Could connect to node? See the logs for". I have attached a screenshot.
Any ideas of how I can resolve this issue?
Thanks!
The mistake I was making, The path that I pointed to the geth.exe in commandline was from a download outside of the Ethereum dir. When I ran geth from ethereum\Ethereum-Wallet-win64-0-6-2\Ethereum-Wallet-win64-0-6-2\resources\node\geth as opposed to desktop/geth that I downloaded separately then Ethereum began to run as expected.
I hope this helps someone else in need!
