Post subject: Eclipse Corrupting Vista User Profiles

I’m using MyEclipse on a Windows Vista machine. By default is stores quite a lot information in the user profile even though the workspace is elsewhere on the machine. In consequence I’ve had it “corrupt” my profile a couple of times (Windows not liking long file names, too much stuff in the profile etc.) and cause Windows to hang when it tries to sync the profile to the server. To work around this I manually delete the profile info from the server and start again. How can I tell it to store the contents of .MyEclipse and .Eclipse somewhere else (like just locally on the c drive rather than in profile space)?

You clarify the directories and files you mean? The only file we create in the user-home directory is the subscription information file. If you haven't placed your workspace or install dir under your user home dir, I'm not sure which files you are referring to.

What server are you referring to, and which profiles are you referring to? I'm really not clear on what you are reporting... is this a WebSphere/Profile issue by chance?

Hi,

Thanks for coming back to me so quickly - sorry if my original post wasn't clear.
Eclipse is maintaining roughly 45mb, 2,500 files, and 270 folders in my Windows profile.
These are things like:
.eclipse\com.genuitec.eclipse.xml.rcp.product_6.0.1.qualifier_100445271\configuration09659606840
.eclipse\com.genuitec.eclipse.xml.rcp.product_6.0.1.qualifier_10044571\configuration\org.eclipse.update\last.config.stmp
.eclipse\com.genuitec.eclipse.xml.rcp.product_6.0.1.qualifier_100445271\configuration\org.eclipse.update\platform.xml
.eclipse\com.genuitec.eclipse.xml.rcp.product_6.0.1.qualifier_100445271\configuration\org.eclipse.update\history09659608930
\.eclipse\com.genuitec.eclipse.xml.rcp.product_6.0.1.qualifier_100445271\configuration\org.eclipse.osgi\.manager\.fileTable.4
\.eclipse\com.genuitec.eclipse.xml.rcp.product_6.0.1.qualifier_100445271\configuration\org.eclipse.osgi\.manager\.fileTable.5
org.eclipse.platform_3.3.0_983489812\settings\c
and so on

Corporate network runs a roaming profile. So things that are saved to my Windows profile like these get copied up to the server and copied down when I log on to another machine.

Quite a lof of these have rather unusual file names - org.eclipse.ui.ide.prefs for instance. Vista periodically has trouble dealing with these. This wouldn't matter (Windows doesn't actually need to handle them as such so long as Java/Eclipse is ok) but having them in my profile means windows has to sync an extra 45MB of stuff every time I log on and off. And this is Windows Vista which has a file copy routine that would make a Commodore 64 flush with pride at how fast it suddenly seemed. It takes about 10 minutes to log off/on every time I do it - and periodically it hangs because it can’t handle a very long file name, or because it just feels like it, or whatever.

As far as I’m concerned replicating this stuff isn't especially useful or important - I'd rather store it somewhere more appropriate like C:\Program Files\MyEclipse6\StuffEclipseProboblyNeedsButIDontCareAbout\
so I don't have to keep getting some poor unsuspecting sysadmin bloke to delete half my profile from the server every few weeks.

I’m thinking there must be a setting for this somewhere but if there is I’m yet to find it.
