Error at installation [message #1747169]

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.

I have no trouble accessing the update site https://otto.takari.io/content/sites/m2e.extras/m2eclipse-buildhelper/0.15.0/N/0.15.0.201405280027 in my Repository Explorer view. Are you able to access that jar file in a browser?

I have no trouble to access the file inside my browser, but if I put the path inside the repository explorer it seems that it can't find anything.

When I installed it at home I hadn't any problem.

When you say the repository explorer can't find anything, is there an error message saying "No repository found"? If you use this same URL with Help -> Install New Software... does it fail to load that repository as well? Have you configured the network settings for the proxy/firewall?

The error is:

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 target server failed to respond

If there was a problem with the network settings/firewall I would have the same problem for the other repositories but this is not the case.

What did you paste in the URL field, just "https://otto.takari.io/content/sites/m2e.extras/m2eclipse-buildhelper/0.15.0/N/0.15.0.201405280027" or did you include the "content.jar" part? Don't include that part...

I also asked you to try the URL (of the repo, not of the content.jar) in the Help -> Install New Software. Did you do that? Please try that.

Given it doesn't fail for me and it only fails in your office, I don't think you should conclude that therefore there is no issue with the settings/firewall. All this kind of seems to indicate that there is indeed some problem specific to your network location...

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.

So reading between the lines, I assume Install New Software also fails for this site.

In a browser, I noticed the URL seems to redirect to https://repository.takari.io/ which then never seems to finish loading. I also notice that https://repository.takari.io/content/sites/m2e.extras/m2eclipse-buildhelper/0.15.0/N/0.15.0.201405280027 works directly in the browser to show the contents of that repo in the browser. That URL also works in the Repository Explorer. Perhaps this redirection of a secure https connection to a different host is something your proxy/firewall detects and blocks as being of questionable security origin.

Perhaps you can try if this alternative URL works better in the IDE...

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.

I don't understand what you're saying. Is there an outstanding question?

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.
