Eclipse 3.3.2 - compiling workspace takes an extremely long time. [message #335109]

Good morning,

I am running into the problem where the recompilation of the workspace
(Dynamic web project) is taking an extremely long time.

I have run into the problem in the past and seemed to be solved by going to
a clean Eclipse image, but it is occurring again.

I kind of get the feeling that it is related to some combination of plugins
that I have but have no clue how to track it down.

Is this a known problem or has anyone else run across this.

Thanks in advance.

One thing you can do is run Eclipse with eclipsec.exe rather than
eclipse.exe; that will give you a console window. Then, while it's in a
slow build, you can hit Ctrl+Break and that should give you a thread dump.
Do a couple of thread dumps and you may be able to get a sense of what part
of the code is taking so long.

Dynamic web projects can be slowed by a number of things. One is schema
validation, if it has to go out on the network to find a schema. Also if
there are large jar files on the classpath, it can exceed cache limits and
start thrashing in some cases.

In the past, I've experienced a very slow build due to a schema
validation. Also if you have other facets, they might also consume a good
amount of time (like Cypal Studio for GWT, which triggers GWT Compiler
during a build)
