I am getting erratic behavior from Eclipse (3.7.0) all of the sudden… this never used to happen, and as far as I can tell I haven’t done anything or changed any settings that would incur this kind of behavior.
Every time I want to run a Java application (as a saved Run Configuration), I now need to Project >> Clean the project first. Otherwise, Eclipse will run the application from a “cached” state (whatever the code looked like the last time I cleaned it).
But, every time I clean the project, it attempts to build my entire workspace. This process takes about 2 minutes.
So every time I want to tweak some code and run my app, I need to clean it (why?!?!) and then wait for Eclipse to build every other open project in my workspace…again, why?!?!
This has been happening for about a week now, with no obvious system-level changes on my part. I have tried restarting both Eclipse and my machine to see if it was a temporary “hiccup”, but it seems to be the new default behavior.
Make sure you have checked the option Build Automatically under the Project menu. On the other hand, be aware that, by default, the clean option (under Project menu) tries to clean all the projects in the workspace. You will have to move the radio button to the option Clean Projects selected bellow in order to clean a subset of the projects contained in your workspace
