Disable the building of one project in an Eclipse workspace

I have a workspace with some projects of mine and a really big project, which takes two hours to be built. I would like to disable the automatic building 开发者_JAVA技巧of this wide project while maintaining the build enabled for the other projects. Is that possible? How would I do it? Is there other options to solve my problem.

You can "close" the project (right-click "Close Project"); that stops Eclipse from looking at it altogether.

Alternatively, in the project properties, under the "Builders" tab, you could uncheck "Java Builder". I think this would turn off compiling and (most?) error checking.
