Setup Grails in GGTS 3.4 behind Proxy - grails

Question

I wish to share the knowledge that how I fix the proxy problem to setup GGTS in my company's PC after I run the setup.exe of GGTS 3.4 downloaded from SpringSource (by googling for a whole day around www ;))
Problem:
When I start to build my hello world project after the IDE installation, GGTS prompts me this error message: "Error Failed to resolve dependencies". How to fix it?

Answer 1

I'll answer my own question:
Go to IE and find the proxy url from the specific proxy file (in Internet
Connection Settings), or just ask your firm's support guys.
Go to your grails' bin folder and run this:
grails add-proxy client "--host=your.proxy.com" "--port=xxxx" "–noproxy='localhost'"
It will give you a line of feedback like: "Added proxy client to \\path.grails\ProxySettings.groovy". Now you should open the file, check the url, port, username & password, and also make sure it contains a second line like this:
currentProxy='client'
There is an article suggesting changing a string in the first line of the ProxySettings.groovy from http.proxyUser to http.proxyUserName. In my own case the proxy doesn't require un/pw so not sure if it is vital or not (source: http://web.archive.org/web/20130910035021/http://jira.grails.org/browse/GRAILS-10097)
Now right click the project in GGTS, Grail Tools > Refresh Dependencies, or just re-create the hello world project. Huray!

Answer 2

ender's answer is fine when you have already run the project at least once, but recently I had a situation where I checked out my project from git on a computer behind a proxy, and I couldn't do "grails add-proxy" because I was behind a proxy and it couldn't get grails dependencies from repos :)
in that case, the solution is to do System.setProperty("http.proxyHost", yourProxy)
in BuildConfig.groovy like this:
grails.project.dependency.resolution = {
System.setProperty("http.proxyHost", yourProxy);
System.setProperty("http.proxyPort", yourProxyPort);
...
}

If you are running GGTS first time behind your company proxy you might get this Error:
Solution:
Go to C:\Users\[your username]\.grails folder, Add a folder name called ProxySettings.groovy.
Expected
Open ProxySettings.groovy file with notepad and add these Two following line:
client=['http.proxyHost':'Proxy Host Address', 'http.proxyPort':'port Number', 'http.proxyUser':'username', 'http.proxyPassword':'password']
currentProxy='client'
Note: Don't Remove single quote.
Final: For Me The content inside file look like Below:
client=['http.proxyHost':'192.150.1.1', 'http.proxyPort':'80', 'http.proxyUser':'Vineet', 'http.proxyPassword':'GoGetHigh']
currentProxy='client'

Answer 4

Edit File ProxySettings.groovy in windows User directory
C:\Users\YourUser
client=['http.proxyHost':'proxy host address', 'http.proxyPort':'proxy host port', 'http.proxyUser':'', 'http.proxyPassword':'']
currentProxy='client'

Answer 5

grails add-proxy client "--host=your.proxy.com" "--port=xxxx" "–noproxy='localhost'"
grails set-proxy client
Then replace maven with ivy in your project's BuildConfig.groovy.

Answer 6

Here is how I fixed the problem for myself for Grails version 2:
Go to C:\Users\\[your username]\\.grails folder, make a file called ProxySettings.groovy.
Inside that ProxySettings.groovy file, add the following two lines:
client=['http.proxyHost':'the proxy host', 'http.proxyPort':'the port number', 'http.proxyUser':'username', 'http.proxyPassword':'password']
currentProxy='client'
For example you can have something like this in the file:
client=['http.proxyHost':'1.1.1.1', 'http.proxyPort':'8080', 'http.proxyUser':'batman', 'http.proxyPassword':'superman']
currentProxy='client'
This does the trick for me and hope this will help you too.
