I've been trying to use the installer for the last two days (from the catalog OpenDaylight : option =No projects) without any lack. The problem seems to be the following one:
ERROR: org.eclipse.equinox.p2.transport.ecf code=1002 Unable to read repository at https://otto.takari.io/content/sites/m2e.extras/m2eclipse-buildhelper/0.15.0/N/0.15.0.201405280027/content.jar.

The installation is behind a corporate firewall but I don't think that this is the problem.

Of course I did what you said. This is not the problem.
As I read some posts regarding proxy settings I agree with you that something happens with the proxy server and the specific site (Nexus Repository Manager). I will check it a little bit more with the IT department. I don't think that I have to set something special in the OOMPH proxy settings (HTTP/HTTPS/SOCKS). I don't know if there are specific guidelines for proxy server configurations.

There isn't any lack. It seems that the installer doesn't cooperate well with the corporate proxy servers. Only when you give direct access it works. I don't know if there are some specific proxy access policies in order to give access to the installer while contacting the repositories.

What I am saying is that I tried to use the installer behind two corporate networks behind proxies. I contacted the IT departments in order to monitor the traffic, just in case there is a problem with the proxy settings.
What I saw is that I have problems like:
- Server not respond (like the case of Takari site). In this case it seems that the installer gets a zero size response.
- Repository not found
- (only at once I noticed that) Fetching compositeContent.xml from http://download.eclipse.org/technology/m2e/releases/1.7/

- The problem seems to exist only when I am trying to install something from the OpenDaylight Catalog and not from the Eclipse Catalog.
Maybe it is something simple, but I miss something. From what I understand there aren't any special orders for running the installer behind proxies/firewalls.
Only when I give to the installer direct access without proxy it may continue.

There are only the proxy preference settings.Quote:

You mean only when you're not behind a firewall? As I said, I can only test and reproduce problems using Fiddler.
If you have questions, try to phrase them in the form of a question with a question mark so I know specifically what you're expecting from me.
