eclipse takes long time to initialize

After selecting the workspace, eclipse takes about 10 minutes to initialize? What could be the pro开发者_Python百科blem?

besides eclipse.ini

try this

 Preferences -> General -> Startup and Shutdown -> Deselect all plugins (if you have ADT, leave it)

also :

Preferences -> Maven -> Uncheck "Download repository index updates on startup"

Eclipse shouldn't take this long to initialize unless you have a lot of plugins (especially buggy ones) installed. Do you get the slowdown after the workbench is already shown? That could indicate a plugin.

You may want to verify with your Eclipse installation how much max heap it is allocated. Eclipse traditionally ships with a very low default for modern machines. If you are on Windows, look at eclipse.ini in your Eclipse directory and change the -Xmx parameter to something meaningful (e.g., 2048M)

Try:

• this eclipse.ini
• running eclipse with the -clean option

Such a long startup time is usually the sign of some kind of timeout, because a resource (path, internet address?) does not respond.

I had the same problem and solved it by setting the socks proxy to the same settings as my http proxy in Window > Preferences > General > Network Settings. My eclipse start time went from 10 minutes to 20 seconds.

Check your workspace size. If its more than some 500 MB then its a problem. Drilldown to the file with maximum size and try to remove or move it out. I had similar problem and found out that there was one movie file of 1 GB and that was causing eclipse to slow down initialization.

If your workspace has many open Working Sets, depending on your settings at start-up Eclipse might be building them all.

If this is the case, you could:

• deselect unused Working Sets:

  • in the Project Explorer, click on the drop-down triangle
  • in the drop-down, Select Working Set
  • in the panel that appears, deselect those you don't need

• if you don't want to deselect Working Sets, you could close projects you don't need all the time:

  • in the Project Explorer, right-click on a project and click on Close Project
  • OR, right-click on a project and click on Close Unrelated Projects (this reduces the start-up time drastically)

Make sure your eclipse.ini doesn't contain the --clean parameter from a previous run.
