Are you relying on your workspace for those dependencies? And if you are using m2e plugin, you might want to try this: Project -> Properties -> Maven -> Disable Workspace Resolution Any time you want to go back to internal resolution and not relying on Maven repository, you can switch back to Enable Workspace Resolution.

How to shut down your PC automatically

If you need to leave your Windows PC running all night and don't have time to turn it off in the morning, you can utilize Windows services to shut down your PC automatically. It isn't easy to reverse and turn on your machine though. Also, you need to pay attention to the fact that this is going to be a daily / weekly / monthly task in your system. So don't forget to delete it if you don't want it any more. 

For windows 7:
1. Go to Start > Control Panel > System and Security > Administrative Tools and click on the Task Scheduler.

2. From the Action menu in Task Scheduler, click "Create Basic Task..."

3. In the "Create Basic Task Wizard" windows that pops up, Type in a title and a description. Something basic like "PC Shutdown."

4. Click "Next."

5. On the "Task Trigger" screen, choose the frequency with which you want the Shutdown PC to run. For nightly shutdown, click on "daily" and click the Next" button.

6.On the "Daily" screen, enter the date and time you want your PC to shutdown. Click "Next."

7. On the "Action" screen, choose "Start a program" and click "Next."

8. On the "Start a Program" screen, type C:\Windows\System32\shutdown.exe in the "Program/script" text field.

9. In the Add arguments text field type /s.

10. Click "Next."

11. Confirm your settings on the Summary screen and click "Finish."

An effective way to rename files in Windows

You need to run the command below in the PowerShell. PowerShell can be thought of an imitation of command lines in *nix based operating systems.

Dir will feed all the files in a folder to rename-item command, and it replaces BEFORE to AFTER for all files in that folder.

Dir | Rename-Item –NewName { $_.name –replace “BEFORE“,”AFTER” }

Find your Voicemail number on your iPhone

If you ever wonder how you can find your voicemail number on your iPhone, there is an easy way of doing it. Just go to the dialler and typ*#5005*86# and hit call. I am not sure if it applies to all handsets out there, it won't hurt if you give it a try on your non Apple handset though!
