Re: [m2e-users] Having a Bad Week - eclipse sick

Thanks for the info, Erik.

Multi-module projects?  Maybe. Depends what you mean by this.

Here's what I do:

In the system that I've evolved there are multiple modules each in it's own Eclipse project, tied together by aggregator projects that are used to build the whole system (outside of Eclipse). Builds are external. I never use anything built by Eclipse outside of Eclipse. Each of these Eclipse projects has its own SVN "project" which is really a subproject of a master SVN project for which there is no Eclipse project. Checking out from SVN in Eclipse means going to the SVN repo view, expanding the trunk or branch of the master project desired, selecting all of its child subprojects and checking each out. I believe if I try to check out the branch or trunk it asks me if I want to check each out as a separate Eclipse project to which I answer yes and it amounts to the same thing.

Merges and such are performed on the whole set of subprojects which are in a working set. Or I sometimes perform them outside of Eclipse on the command line, primarily because I was using an older version of subversive which had some severe flaws in merging that have been fixed in the newer one. A while back I was using subclipse, but had issues with that as well and switched to subversive. Not sure which is better. I guess for the most part, they both work.

64 bit?  No, I have a 32 bit machine and that's that.

On the other hand, yesterday was a relatively good day. Not a single crash on a fairly heavy development day, using my stripped-down Eclipse, though things were occasionally slow. Interestingly, perhaps, yesterday I was in the office. Usually I work from home. Hmm. I wonder if the VPN plays a role in slowing all this down, what with dips to the corporate Nexus, to the SVN repo, etc. Or maybe this is a coincidence. I need to track this possibility I guess.

I've had similar experiences (mostly related to slowness) once we migrated
our project to a multi-module project using m2eclipse, despite my attempts
to make sure I'm giving it enough memory and stripping eclipse down to the
bare minimum.  It got so bad that many of our team migrated to IntelliJ
and are happy as can be.  However, it's an open source project that we
work on, so I felt like it was important that it at least be possible to
build the project and everything in Eclipse so I've been trying to
persevere and create the semblance of a workable development environment
with Eclipse.

That said, one thing you might try which seemed to help us a little bit
(though I don't understand why) was to use the 32-bit version of Eclipse
instead of 64-bit.  It seemed to consume less memory, prior to that we
would exceed 350 mb of perm space just checking out our project from
subversion and building it.  So it may not help you out much but it might
be worth trying if you are currently using 64-bit.

Good luck,

and, sad to say, it's mostly because of the combination of m2eclipse,
helios, subversive and the whole fracking mess.

Eclipse has become less and less usable.  I don't know who's to blame,
which plugin is the cause or whether it's the whole platform or some
combination.  Rare is the day of heavy development where Eclipse doesn't
crash many times.

Every crash is different.  Sometimes I have to delete the .lock file.
Other times I don't.  Other times I can't do it without killing processes.

How many minutes am I losing waiting for updates from the Maven
repository.  How careful I must be these days when clicking the mouse,
if you click when something else is going on, that's just asking for

And then there are things going on in the background that you don't even
know about.

I decided I may have had too many plugins installed.  So I built a new
Eclipse installation using the latest and only what I really needed:

m2eclipse, whatever the latest that's available today
hibernate plugin

No C, no google windowing toolkit, no perl, no python, no shell script
editor, no nothing I don't use daily.  That other stuff is in my old
installation for when I need that.

Did it help?  Not much.  I still wait more than I used to.  There are
still user interface actions that provoke crashes.  I created a new
workspace,and hit one of those problems in ten minutes.

I don't know who to blame but this world has gotten out of hand in the
last six months.

I am on a Windows XP platform with 4GB RAM.  Is that not enough anymore?
