When building our Java applications in Eclipse, the Spring builder is very slow and gives no status updates.

Specifically, I start building a project, and Eclipse’s Progress pane displays

Invoking ‘Spring Project Builder’ on ‘project name’…

for multiple minutes at a time, with no additional details.

I’ve already turned off the Spring AOP Reference Model Builder, and I just recently disabled the Spring project builder completely out of desperation.

I’m just building and using these projects, not developing them, so theoretically they should compile fine – but this is our development branch, so I’d still like to keep Spring on in case there’s a nasty reflection error somewhere.

So, in order to keep using them, is there anything I can do to:

  1. Speed the Spring portion of the build?
  2. Display more detailed output during the Spring project building process?

I’m specifically referring to the Spring IDE plugin in Eclipse.

    I’m assuming you’re referring either to the Spring IDE plugin for Eclipse, or the SpringSource ToolSuite bundle.

    The big performance killer that I’ve nailed down is the processing of <import resource="..."/> entries in the beans files. The plugin has an option for enabling the processing of these, and if turned on, it absolutely hammers performance – it searches the entire classpath (including libraries) for each imported resource, ever ytime something changes. I reported this as a bug, and thankfully it’s been fixed, but not yet released.

    The <import> support is just a nice-to-have, though, since you can manually add the imported files directly. Turning it off makes the whole experience much more edifying.
