The Build Automatically option does not consistently work on 3.1 M7. For example, the Build Automatically option is on and a project may show up as having build errors. Manaually cleaning the project will cause the project to be rebuilt and the errors to disappear. This indicates that the Build Automatically option is not having an effect. This can be very confusing for projects that were previously compiling without errors. Because the project is not rebuilt, modifications made to the code will not have an effect. This issue is reproducible, although there does not seem to be a consistent way to reproduce it.
Does this problem still happen using latest RC2 nightly build or at least RC1?
I'm having a similar but not identical problem with 3.1 (I20050627-1435). I'm using the 1.5 jdk but still have the 1.4 compatability mode on, if that matters. Also, I'm running on win2k, not XP. After making a change and doing a clean all, with "Build automatically" checked, several of the projects will show problems (even though there are no actual problems). Each says that it (A) can't be built until some other project B is built. Tracing the chain of dependencies I find an erroneous problem, where A depends on B and says B hasn't been built, but in fact B has been built without problems. If I then clean just that project A, it (and sometimes one or two others that depend on it) successfully build. Eventually I can get the whole workspace built that way (I have 28 projects in the working set). There is another problem - not sure if it's related (but it's what's causing me to try to rebuild all). We have a UnitTest program that scans through all our projects and runs all the TestCases it finds. After making some changes, I'm often getting ClassNotFound exception for the class I just modified when running the unit tests. After going through the rebuilding process described above, the problem goes away and everything runs normally.
Please reopen if this problem still occurs using 3.1.2
As of now 'LATER' and 'REMIND' resolutions are no longer supported. Please reopen this bug if it is still valid for you.
