Description Miguel Angel Garcia Grande CLA 2010-09-21 05:37:33 EDT
Build Identifier: Version: Helios. Release Build id: 20100617-1415

This bug is similar to 305172 but also happens when modifying user libraries.

Say we have Java project and it's build path includes a user library. In Eclipse 3.5 (Galileo), if you update one of the jar file into that user library (same name, different content), Eclipse automatically rebuilt affected projects.

This is nolonger true for Eclipse 3.6. In order to achieve this, you have to modify a source file.

Reproducible: Always

Steps to Reproduce:
1. Create a jar file containing a class named "A".
2. Create a user library containing the jar file.
3. Create a Java Project.
4. Create a class "Test" that uses class "A".
5. It won't compile, so you'll have to add the user library to the project's build path. So far, so good.
6. Create a new version of the jar file WITHOUT class "A".
7. Java project show no error until you modify and save "Test" class (even "refresh"ing the project doesn't make it notice the change).

No, it doesn't seem to be an issue with build I20110428-0848. Please try with this build or newer and let me know.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
