Extremely slow "Updating classpath" on Eclipse startup [message #571982] Thu, 04 February 2010 17:21 Go to next message

In my multi-module application, at each eclipse startup, there is
an "updating classpath" phase launched by IAM for each module. Each phase lasts for 2 to 10 minutes, resulting in an extremely slow startup.

The event view does'nt show any event.

Any idea ? I know there has been a lot of discussions on the subject, but I coul'ndt find a tutorial for getting rid of this.

are you using the last 0.11.0 ?

how many projects do you have opened?

the maven event view is the one you are checking?

Carlos,

I found a solution !

The event view was already open, but I hadn't seen the filter options.
I set the filter to "debug", and saw a message : maven was stuck in trying to download sources for jars in all repositories,
and not founding them anywhere.

I deactivated the "download sources" option in maven preferences, and starting time is now OK .

The only problem remaining is that the option is not very useful, as I can't activate it.

I don't know if it is a bug, but I think there should be at least a serious warning on that option.


Thanks anyway for your responses. I hope this discussion will help other IAM users too.

you dont have internet connectivity from that machine, or use a proxy?
at startup it'll try to download the sources, but if they are not
present it will just take the time it takes to ping a remote server. I
think the issue is that instead your http requests are timing out, which
may mean 30 seconds or more for each missing source

even with "download sources" unchecked you can right click on the
project and in the Maven menu there's a download sources command

I use the proxy of my company, but can"t say what impact it has on Internet search performance.

probably is not properly configured in your $HOME/.m2/settings.xml
and/or Eclipse Proxy preferences, and that causes the requests to time out
