Please provide the errors logged during a failed install. I just tried it and it worked fine for me, no errors whatsoever (even though it was quite slow).
@jgsuess Saw your comment on the Marketplace:
This plugin is offered on the marketplace using jar:// URL that ends in a zip file for the site. Most corporate proxies will block this access from automated user agents. This probably means this plugin cannot be installed in most major companies. To address this, the project might want to stage a regular P2 repository layout.
JAR URLs are resolved inside the JVM, your proxy will not see a request for that URL, but for the encapsulated URL only. So, for this JAR URL:
jar:http://repository-textuml.forge.cloudbees.com/snapshot/com/abstratt/eclipsegraphviz/com.abstratt.eclipsegraphviz.repository/2.2.201606/com.abstratt.eclipsegraphviz.repository-2.2.201606.zip!/
the actual URL Eclipse will try to hit is:
http://repository-textuml.forge.cloudbees.com/snapshot/com/abstratt/eclipsegraphviz/com.abstratt.eclipsegraphviz.repository/2.2.201606/com.abstratt.eclipsegraphviz.repository-2.2.201606.zip
Did you manage to access the error log? (Window > View > Error Log, or
Also, if you are having connectivity issues, a workaround is to download the update site (http URL above), and install EclipseGraphviz from the locally download (zipped) update site.
So the url being resolved is not for a zip archive, the response does not identify the content type as a zip, and the data being retrieved is not a zip file? Under any of those circumstance the proxy would probably block. What I am trying to say is that a zip file provided over http that is not on a whitelist is likely to be blocked.
I will provide detailed error once at work.
Thanks for the prompt response!

@jgsuess It is a zip file:

Also, if I grab the file:

No errors detected in compressed data of test.zip.
And so it probably gets blocked. I assume it is the hosting location that is the issue. Many proxy Configs in large companies block odd combinations of UA and destination. One way to block backdoor downloads from their perspective.

@jgsuess That is unfortunate. If you confirm you can't download the zip file not even directly via the browser (how do you get Eclipse? Would .tgz resolve the issue?), you can try this other URL:
which is a GitHub "release" I created to get you unstuck.
Eclipse downloads are whitelisted. In particular, the delivery server DNS name. I'm unsure what UA string eclipse uses when accessing the outside. I would need that to reproduce.

I believe it uses ECF, which I believe uses Apache HTTP client. But does the UA matter? Are you able to grab the .zip file using a browser?
Just arrived at work 6.46 am. Booting up and will let you know in about 10 minutes.

I cannot get the archive using curl
, but can get it using the browser.
but eclipse reports:

Oh, that I have seen once in a while as well. At least you have the workaround of downloading the .zip file and installing from the archived update site - right?
Yes, that works reliably. But I think this issue might turn people off an otherwise nice tool. a.k.a. I have to do what to install it? You must be kidding...

@jgsuess Thanks for confirming it.
Agree that it is not ideal, but it is what we have for the moment with our current build infrastructure.
I added to the readme an installation method number 3 explaining the problem and how to work around it. Thanks for helping in understanding it.
Update site now is http based and should work behind a firewall/proxy as well.
in Version: Neon.2 Release (4.6.2) Build id: 20161208-0600 both versions of setting up the tool (marketplace, direct jar URL) do not work.
