Robert Munteanu commented on SLING-8700:
----------------------------------------
This I've tried and did not work:
- disabling the Maven Builder for the affected project
- deleting .settings/.classpath/.project and reimporting all projects
- upgrading to Eclipse 2019-09
It's interesting that at some point during import output directories named
{{bin}} are created, but they don't seem to be updated. Maybe a side effect of
the configurators?

In this example the {{ServerUtil}} class in target/classes is newer than the
one in bin.
The simplest way to reproduce:
* Open {{ServerUtil}}
* add a dummy change, save
* add another dummy change, save
At this point I get some compiltation errors in ServerUtil but also in
SlingLaunchpadBehaviour

In the screenshot it's clearly visible that the error is present on the method
invocation, but not on the type name and not on the import.
[~kwin] - does this problem happen to you as well?

> Project: Sling
> Issue Type: Task
> Components: IDE
> Reporter: Robert Munteanu
> Assignee: Robert Munteanu
> Priority: Major
> Fix For: Sling Eclipse IDE 1.2.4
>
> Attachments: compiler-errors-screenshot.png
>
>
> 1. Change any code in eclipse-ui module in Eclipse
> 2. Run the plug-ins as an Eclipse Application (Sling IDE Tooling shared
> launch config)
> Result: eclipse-ui fails to start, logged event _An error occurred while
> automatically activating bundle org.apache.sling.ide.eclipse-ui (536)._ Error
> is attached, but root cause are compilation errors in
> org.apache.sling.ide.eclipse.ui.internal.Activator.<init>, e.g.
> AbstractUIPlugin cannot be resolved to a type
> ServiceTracker cannot be resolved to a type
> SerializationManager cannot be resolved to a type
> SerializationManager cannot be resolved to a type
> ServiceTracker cannot be resolved to a type
> FilterLocator cannot be resolved to a type
> FilterLocator cannot be resolved to a type
> Note that these errors are not reflected in the editor.
> Solution is usually to clean the affected project.
> The same applies to the eclipse-core plug-in, so I assume this is not
> isolated to a single Eclipse project. Iit does not apply to
> org.apache.sling.ide.api or org.apache.sling.ide.artifacts, so I assume this
> is related to the projects under '/eclipse' only, not to those under
> '/shared'.
> It also happens that when editing a class ( e.g. JcrNode ), random compiler
> errors pop up in the same project.
