--------------------------------------
Summary: IvyDE classpath containers become empty on
eclipse/MyEclipse startup
Key: IVYDE-317
URL: https://issues.apache.org/jira/browse/IVYDE-317
Project: IvyDE
Issue Type: Bug
Components: classpath container
Affects Versions: 2.2.0.beta1
Reporter: Michael Ondrejko
Priority: Blocker
As J.C. mentioned, we have found that when we enable "Resolve in Workspace" for
the IvyDE classpath containers, we consistently see that containers become
empty in our projects. When this occurs, it may be as simple as performing an
Ivy -> Refresh (or combination of Ivy->Refresh, Ivy->Resolve, and file
Refresh). However, it may also require removing and re-adding the classpath
container manually.
While attempting to setup a test-case to demonstrate the problem, for some
time, I was not able to consistently reproduce any of the issues that I
encountered. Some of the issues that I did see along the way include
• when changing ivy.xml directly, upon save only one (of two in my
case) classpatch containers would be updated to reflect the changes
• when importing a project, sometimes one or more/all classpath
containers would not be created. A manual Ivy->refresh was required
• losing the export setting on one of the Ivy classpath containers
• random disappearing IvyDE classpath containers
What I eventually found is that in our application project environment, we have
Eclipse set to refresh files on startup. When I set this in my test
environment, I consistently see the behavior described where IvyDE classpath
containers disappear on eclipse startup. Note that I have Ivy set to “Do
Nothing” and “Refresh” and both have consistently resulted in the issue.
I have attached the sample projects from my investigation. Unfortunately, I was
unable to include the eclipse workspace itself due to file size limitations. I
believe the only significant change in the eclipse environment is to set
Refresh on startup in General->Startup and Shutdown. Let me know if you have
any other questions.
Thanks and I hope this helps you resolve the issue more quickly.

We've found it gets worse with "Resolve in Workspace" active. Michael
is actively working on a test case that doesn't require us to send you
our entire codebase. :)

It appears that when I shut down and restart Eclipse the Ivy Classpath
Container loses its contents. I could swear sometimes it doesn't, but almost
always when I restart Eclipse, it is empty until it does an automatic Resolve
when I bring up Eclipse.
What we'd like to see is that the Ivy Classpath Container actually persist its
contents, even between Eclipse restarts. So that when Eclipse comes up, no
resolve is necessary. And at times, I really don't want to do a resolve,
because it will trigger download of stuff I really am not ready for yet. I'd
like to control when I resolve and get new stuff downloaded, so right now the
only choice I have is to either check the checkbox to Resolve on Launch, or do
a manual resolve. This usually also causes an entire rebuild of the projects,
which sucks, because that can take 10-40 minutes depending on how good the
hardware is.
So, is there a way to make the Classpath Container remember its contents, even
between Eclipse restarts, and never lose it until the project is either deleted
from the workspace, or another resolve is done?
It is supposed to work. But like you I have noticed that sometimes it looses
its content too, which is boring me too. I have never took time to investigate
though.
