Eclipse suddenly takes 5+ minutes to start

I'm using Eclipse Galileo (v3.51). All of a sudden, after weeks of it starting up in about 30 seconds or so it's taking 5+ minut开发者_开发百科es. The message it hangs on org.eclipse.jst.jsp.core

Any suggestions?

Which flavor of Eclipse are you using?

I have had bad experiences (like yours) with some plugin combinations -- especially Mylyn combined with the Maven Eclipse Plugin.

I saw in your answer that your workspace metadata was corrupted. You may want to consider running Eclipse with the -clean flag occasionally. I've been doing that and it always runs well.

Turns out something got trashed in my workspace metadata. Once I cleared that (and lost all my workspace settings), everything went back to normal.
