Hi,

I have added the AJDT update site to the Eclipse update manager. I set
its update location to
"http://download.eclipse.org/tools/ajdt/32/update" as it says on the
AspectJ page. Every time I try to update though I get an error message:

Network connection problems encountered during search.
Unable to access
"http://download.eclipse.org/technology/ajdt/32/update/".
Unable to access site:

This has happened for the last month or two...

That site has moved to http://download.eclipse.org/tools/ajdt/32/update/

Try that!

I must be missing something here - that is the URL that I have given the
update manager (as I explained in the first part of my email).

Am I supposed to specify this somewhere else as well? I don't see why
Eclipse is trying
"http://download.eclipse.org/technology/ajdt/32/update/" when I have
changed the URL to "http://download.eclipse.org/tools/ajdt/32/update".
The only way I found of changing the URL was to go Help/Software
Updates/Find And Install. Click on Find New Features and then edit the
URL for the aspectj there. Is there somewhere else I am supposed to
change this? I expected to be able to do this in the Manage
Configuration... menu item for updates but cannot find anywhere to
change the URL there.

Thanks,

Nicholas Allen

I can access the update site just fine. The latest version of AJDT is
1.4.1. Of course, I'm starting from a configuration that doesn't
currently have AJDT installed...

Might you have another update site checked in the update manager before
you click the "Finish" button? It could be that, with the AJDT already
installed, it's trying to use its own (old) update site. You should be
able to solve this problem by making sure that the
http://download.eclipse.org/tools/ajdt/32/update update site is the only
one selected.

Thanks for the suggestion but search for updates of currently installed
plugins does not allow the user to select which features (it's always
all installed features). So this is not even possible. You can only do
this when searching for new features to install.

It seems that there is a bug in Eclipse where checking for updates
always uses the location specified when the plugin was installed and not
the currently edited location in the update manager. The only solution I
found was to delete the plugin and reinstall it with the new location.

Should I file a bug report for this? It basically means a plugin cannot
change update location if users have already installed from a given
location so it is quite annoying...

That seems to be the problem. If you installed from an old update
location then this bug occurs but if you install it from the new
location then there is no problem. The only solution I found was to
completely remove the plugin and then seach for new features to install
given the new location. Not really an acceptable solution though...

Argh! It's MUCH MUCH worse than I thought. Even uninstalling the plugin
and then searching for updates with the new location does not work. It
installs from the new location but still tries to update from the old
one so I still get the same error. I have no idea where Eclipse is
keeping this update location as the one I have specified in the update
manager is NOT the one it uses. It always uses the original install URL
even if you uninstall the plugin and re-install it again from the new
update location.

I expected this to be a workaround but was suprised to find out it does
not help. Perhaps I have to reinstall Eclipse from scatch? I will first
try deleting the site from the update manager, uninstalling the plugin
and then re-adding it at the new location and see if that helps. If not
then I will try reinstalling Eclipse from scratch. Hopefully, it's not a
setting in Windows registry that prevents this from working too...

Ok this is getting seriously annoying! Uninstalling the AJDT plugin,
removing the update site and restarting Eclipse, adding the update site,
reinstalling the plugin, restarting Eclipse STILL causes Eclipse to try
to update it from the original install location.

The only solution I see now is to reinstall Eclipse from scratch and
hope that works.

Ok even deleting Eclipse and reinstalling, adding the new update
location does not work. Eclipse insists on using the old update location
no matter what I do. It must store it in the registry or elsewhere. I
give up!

I checked the feature.xml file on the feature and it seems to indicate
the update site correctly. I'm not sure where else it might be getting
this mis-information from.

When you reinstalled Eclipse, did you create a new workspace? It might
be worth trying it from a new workspace to see if it goes away. If it
does, then there's a bug that we need to address, if it doesn't then the
problem is probably somewhere else on your machine (although I'm at a
loss as to what it could be).

Eclipse doesn't install anything in the registry, so it's not that.

I also tried in a new workspace but got the same problem. I think I have
tried everything thinkable but I still get the same error every time.
Perhaps it is a server side configuration issue with the AJDT update
site (doing an HTTP redirect to the old location?). Is anyone else
noticing this when they update AJDT. I am at a complete loss as to what
to do now. I have the same problem on 2 machines (one Linux and one
Windows) and I am unable to find any kind of solution or workaround for
either. It is strange that Eclipse can install the AJDT plugin from the
new location but updates from the old. I have reported a bug in
Eclipse's Bugzilla (https://bugs.eclipse.org/bugs/show_bug.cgi?id=170507)

Thanks,
