Created attachment 279909 [details] Example with three projects I have a plug-in project A which depends on B which depends on C. And C depends on A. Eclipse correctly says: Description Resource Path Location Type A cycle was detected in the build path of project 'a'. The cycle consists of projects {a, b, c} a Build path Build Path Problem A cycle was detected in the build path of project 'b'. The cycle consists of projects {a, b, c} b Build path Build Path Problem A cycle was detected in the build path of project 'c'. The cycle consists of projects {a, b, c} c Build path Build Path Problem The project cannot be built until build path errors are resolved a Unknown Java Problem The project cannot be built until build path errors are resolved b Unknown Java Problem The project cannot be built until build path errors are resolved c Unknown Java Problem Now I remove the dependency in C to A. If I save I still have the following two messages: Description Resource Path Location Type The project cannot be built until its prerequisite b is built. Cleaning and building all projects is recommended a Unknown Java Problem The project cannot be built until its prerequisite c is built. Cleaning and building all projects is recommended b Unknown Java Problem Project Clean All is unable to solve that. To reproduce: Import the three projects from the zip Remove dependency in C to A Save -> Two errors still remain Project -> Clean -> Two errors still remain
Tested with Eclipse IDE for Java Developers Version: 2019-06 (4.12.0) Build id: 20190614-1200 OS: Linux, v.3.10.0-957.27.2.el7.x86_64, x86_64 / gtk 3.22.30, WebKit 2.20.5 Java version: 1.8.0_141
Workaround: Closing and opening all the project solves the problem. However the bug - comment#0 looks interesting.
Created attachment 279910 [details] C doesnt depend on A Making C depend on A causes error ( as expected ) and removing C as depending gives 0 error. My observation ! However the bug - comment#0 still remains !
*** Bug 551147 has been marked as a duplicate of this bug. ***
Why is this bug for PDE? The cycle error is coming from JDT?

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. -- The automated Eclipse Genie.
