I don't know exactly when this happens, but today I found this in my log and I'm pretty sure I already saw this in the past other times.
I'm not 100% sure it's Greclipse responsibility, but I see that there's GroovyCompilationUnit in the stack trace.

Context: I have an Eclipse project handled with Gradle/Buildship which is located in:
<checkout path>\master
The project is imported into the workspace without copying its contents. However, the project name is not "master", but rather it's set to DCS-SHOP in .project file (by Gradle).

I suspect this mismatch between the folder name ("master") and the project name ("DCS-SHOP") is causing this problem in some way.

Additional note: DCS-SHOP is neither a Java Project, nor a Groovy Project. This may be another candidate reason of the problem, perhaps.
However please note that DCS-SHOP contains a Groovy subproject (in master/buildSrc), which is displayed non-hierarchically as a separate project in my Eclipse workspace, named as "buildSrc".

Let me see if I understand. Filesystem:

<git root>
    master/
        .project
        .settings/
        buildSrc/
            .project
            .classpath
            .settings/
            <etc>

Eclipse workspace:

DCS-SHOP (Gradle project that maps to master/)
buildSrc (Groovy project that maps to master/buildSrc/)

Is this right?

I use SVN instead of Git, but the structure is right.
I'm seeing that DCS-SHOP has a .classpath file in it (probably something inherited from the past, I should investigate) but in its .project the only listed nature is org.eclipse.buildship.core.gradleprojectnature, hence for Eclipse it's a plain Project, not a Java or Groovy Project, and its .classpath file should be useless and unused.

This is what I get when I open a groovy source from the master (top-level) project. Is this what you're referring to or are you opening the groovy source from the nested project?

I do not have Groovy sources in the master project, but I do have a Gradle build file (written in Groovy). I did not open that file explicitly but an open editor existed for it when this error occurred.

I see that closing and reopening this editor produces that error in the error log. I'm going to try your latest fix to see if it disappears.

I updated to 3.7.0.v202002262305-e1912, but I still get this exception when I open the editor on build.gradle in DCS-SHOP project:
