every once in a while, compilation does NOT create class files! even "build all" just pops up the progress dialog for a second and disappears. NO ERROR! but the build directory only contains the packages (directories) and no class files! i have to close eclipse and delete all files under my output directory (classes directory) and try again ... after several times, eclipse gets back to create class files. THIS IS CRITICAL!!!
Have never observed this behavior. Do you have steps to reproduce, so that we can investigate ?
Are there any build errors on the project themselves? Or walkbacks in your .log file? Is your workspace on a network drive which is temporarily running out of disk space?
no network drive, nothing special. just one Windows NT 4.0 workstation running eclipse 2.0. a coworker has noticed the same effect on his (different) computer with eclipse 2.0... :-(
Well we're going to need some help so we have somewhere to start... we haven't heard of anything like this. Please check your .log file whenever this happens and attach any walkbacks you find. Include your project's .classpath files so we can see how your projects are configured. Also describe the machines that have this problem: OS version, VM version, etc.
It happened again! Here's the latest entry of the eclipse log: !SESSION Sep 12, 2002 14:45:54.198 --------------------------------------------- java.version=1.3.1_04 java.vendor=Sun Microsystems Inc.

Do you have other tools running and holding pointers to files located inside your output folder ? Note that a task should have been added to report this issue - shouldn't it Kent ?
nope, no other tasks. i have CVS (WinCVS) also running in the background, but my classes directory is not in the CVS, so eclipse is the only task handling my classes directory (that is the build output directory of my project).
I realize you may not remember, but what time did the problem show up vs. the time of the stack trace in the .log file? There are some stack traces written to the .log file which were handled inside Eclipse and not considered bugs or failures.
Is this still happening? Do you have any other walkbacks?
it still happens once in a while. here the last occurence in the .log file: !SESSION Okt 08, 2002 14:43:27.560 --------------------------------------------- java.version=1.3.1_04 java.vendor=Sun Microsystems Inc.

None of these walkbacks are bugs... they are all cases when we detected (& reported against the project) a build problem because there is another application holding onto resources in the output folder, which we're trying to delete. Please double check the errors reported against the project whenever the build fails... you should find an error indicating that .class files or other resources could not be deleted.
Closing until we can tell that this is not just a problem with another process holding onto files in the output folder, when we're trying to delete them.
so, even if some other process holds references to the class files, i consider this a bug as Eclipse just behaves as nothing went wrong, when building the project. a exception in the .log file is not enough as a developer does not show in the log on every compile cycle ;-) as this is a build error (the classes were not created - no matter what reason), the gui should at least display a corresponding error to inform the developer that build was not successful.
"so, even if some other process holds references to the class files, i consider this a bug as Eclipse just behaves as nothing went wrong" That's incorrect. Everytime these messages are logged, we also create an error that appears in the task list. We tag the project with an error that says: "The project was not built. It may be inconsistent, if so ensure no other tool is browsing the output directory, then try refreshing this project and rebuilding it"
task list? i've seen that but have no use of it as it is cluttered with CVS messages. but besides this: if this is printed in this task list, why doesn't the task list pop up? if this occurs, how do i know if there are some entries in a task view? the task view does not pop up on this, so i have to think, that build was successful! i call this a very basic feature, as not all developers know about this task list or even if they know about it, they don't use it or look into it after each compile cycle. at least, if there is such an error, this task list should pop up. there should be at least an automatic viewing of the error without the developer forced to look somewhere himself if the build was successful. isn't that understandable?
"i've seen that but have no use of it as it is cluttered with CVS messages." A red error X is attached to the project itself in the packages view to tell you that the build failed... or did you close that too? ;) You can also set the filters in the task list to remove CVS problems. The task list is important and should not be closed.
okay, i see that i can't convince you for a popup dialog like "build failed - see task view" (which automatically pops up/comes to front. then i have to convince my collegues that they have to carefully watch the project tree node and the task view, as this occured on other computers too and the developers were surprised that their war/ear files (build from ant tasks) were empty because of missing classes. so the current behaviour is not that clear/obvious.
"they have to carefully watch the project tree node" Please describe your workspace/perspectives: 1. Which perspective do you work in by default? Is it the Java perspective? 2. Do you never watch the builder progress dialog? If you do then do you not see it increasing the error count & aborting prematurely? 3. How often or how many errors (ie. red X's) do you have in your project? In other words, do you often work with dozens of errors left to be fixed? If not, then it should be obvious when 'new' errors are detected. The further up the project, the worse the error.

We barely use this, as saving the current editor automatically checks for syntax. when we build the broject, we have our own ant tasks. >3. How often or how many errors (ie. red X's) do you have in your project? In >other words, do you often work with dozens of errors left to be fixed? that depends on the developer. i try to fix the red crosses as soon as they appear (another developer does not). and i noticed sometimes that the root node (project name) had a red cross. but i wasn't able to figure out what it was or how to fix it, as the red cross did not appear lower in the tree, there is no tooltip, and double click also didn't do anything. so i left this root-node-red cross and waited till it disappeared by itself. perhaps this was the indication i was looking for and it doesn't tell me what's wrong. (again: tooltip or popup of task view with error would be nice ;-)
"We barely use this, as saving the current editor automatically checks for syntax. when we build the broject, we have our own ant tasks." Sorry, what did you mean by this? Do you have the option Window->Preferences- >Workbench->Perform build automatically... enabled or disabled? If its enabled then whenever you save changes in the editor, a build is performed. You do not need ant tasks to build your code. If you do want to rebuild your world, then use Project->Rebuild All. "perhaps this was the indication i was looking for" The next time you see a red X on a project, check the tasks view. If you set its filter to "Any resource in same project", you will see the error, since we delete all other errors so this major error is the only one left.
"Sorry, what did you mean by this? Do you have the option Window->Preferences- >Workbench->Perform build automatically... enabled or disabled?" Enabled. "If its enabled then whenever you save changes in the editor, a build is performed. You do not need ant tasks to build your code. If you do want to rebuild your world, then use Project->Rebuild All." i know. that's why we don't use "rebuild all", we just save the changes. what i meant with the ant tasks is, that we have ant tasks that build JARs/WARs and these tasks depend on other tasks, also compile-tasks. so, whenever i want to test my servlet, i just run my ant task "J2EE.deploy" which compiles the project, builds the jar, war and ear files, deploys to J2EE... info: our ant build.xml is not Eclipse specific, the targets need to run also without Eclipse, so we also have the compile targets. so, we also have a target "create.WAR" and for speed reasons, this and some other targets don't do all the compile stuff again and again. the classes are expected to be created. in the error case this bugzilla report is about, sometimes Eclipse does not create the class files but deletes them - which is another strange behaviour of Eclipse: it can't create the class files because some other process is holding reference to them (so _your_ opinion) but on the other hand it is able to delete the classes - now THIS is strange, isn't it? remember the original error: Eclipse does not create class files ... the output directory of the project is empty!
I remember... as far as: "it is able to delete the classes - now THIS is strange, isn't it?" Which would you prefer: 1. Leave an inconsistent set of .class files in the output folder so it takes hours to debug the numerous problems that are caused by the mis-matched files, or 2. No .class files at all so you don't waste your time debugging bogus code? Have you ever tried debugging .class files that don't match the source files anymore? Its not a lot of fun...
I have the same iossue. Lo log file is created. Deleting all class files, even the entire bin folder doesn't fix it. Clean doesn't fix it, it just skips compiling the affexted project. I found a workaround. Delete the project, then re-import it. Don't change anything.
