Question

I am using Eclipse 3.5 for several different Java/JSP projects. All of our project code is stored in Subversion. I use the Subclipse plugin to update / commit code. This works great for all projects except one. There is one project where almost every time I do a SVN update, the entire project becomes riddled with Java compile errors. Most of the errors are complaints that it can t find other class files within the same project. To resolve this, I have to go to Project > Clean and manually clean out the project, which takes a little while to run. Everything compiles just fine after this, but it is a bit of a pain to have to manually clean the project every time I do a SVN update. And this only happens for this one single project.

Anyone experience something like this? I am not even sure where to look to figure out why the project needs to constantly be manually cleaned. Is it possible that someone else is checking in a file that breaks my project build in Eclipse? If so, what file(s) should I look for?

Answer 1

First, excuse me if I say something obvious, but you didn t give any details of your project configuration, nor described your previous attempts at solving this issue. So, maybe you ve already tried everything I m going to suggest... ;-)

Off the top of my mind, I d check whether someone else is committing compiled classes, instead of sources only.

Other than that, it depends on your configuration: I m assuming that you ve got the "Build automatically" flag checked, that you re building through Eclipse only (and not, for example, through Ant, letting maybe the Ant build put its output somewhere in your classpath), and that you re not versioning jars nor your .classpath file.

I suggest (if you re not doing so) to perform your SVN updates going through the Synchronize view (Team -> Synchronize with Repository), in order to see at a glance what kind of incoming changes you ve got, to better distinguish cases when your project gets messed up from cases when it doesn t.

Answer 2

Some one already explained that, may be someone else also committing the compiled classes , and the class paths are getting conflicts. Fist know this info from your collegues and proceed. I didn t come across this situation. sorry.

Answer 3

How are you storing the project on SVN? Are you storing the entire Eclipse project or just source code, structure, etc? If you re not storing the entire project I d suggest doing that as it makes it easier to work with (unless you ve got somebody using a different IDE). Without some more information it makes it hard to diagnose, but it certainly sounds like somebody is committing compiled class paths. You should check the SVN history to confirm.
