Re: [cdt-dev] Cyclic reference between projects

Nate,

I see there has been some discussion on the gerrit. If there is still something else to look into, please let me know.

Hi,

As part of my attempt to fix bug 539307 [1], I added a use of something from EditorTestHelper, in CodanEditorUtility. This required adding "org.eclipse.cdt.ui.tests" to the list of bundles required by "org.eclipse.cdt.codan.ui".

When I pushed this patch to Gerrit, the test run [2] failed with the following error:

[ERROR] The projects in the reactor contain a cyclic reference: Edge between 'Vertex{label='org.eclipse.cdt:org.eclipse.cdt.core.tests:5.4.0-SNAPSHOT'}' and 'Vertex{label='org.eclipse.cdt:org.eclipse.cdt.codan.checkers.ui:3.2.1-SNAPSHOT'}' introduces to cycle in the graph org.eclipse.cdt:org.eclipse.cdt.codan.checkers.ui:3.2.1-SNAPSHOT --> org.eclipse.cdt:org.eclipse.cdt.codan.ui.cxx:3.4.0-SNAPSHOT --> org.eclipse.cdt:org.eclipse.cdt.codan.ui:3.3.0-SNAPSHOT --> org.eclipse.cdt:org.eclipse.cdt.core.tests:5.4.0-SNAPSHOT --> org.eclipse.cdt:org.eclipse.cdt.codan.checkers.ui:3.2.1-SNAPSHOT -> [Help 1]

I don't understand this error. In particular, I don't understand why the last edge, the dependency from "org.eclipse.cdt.core.tests" to "org.eclipse.cdt.codan.checkers.ui", is there. There are no references of any sort to codan in the "org.eclipse.cdt.core.tests" plugin.

Could someone help me understand how the cyclic dependency is coming about?

Thanks,
Nate
