Create the following Gradle multiproject structure inside any folder of your hard disk:

/master
/prjA

In /master put the following file named settings.gradle:

includeFlat 'prjA'

rootProject.name = 'myRoot'

In /master put the following file named build.gradle:

task wrapper(type: Wrapper) {
	gradleVersion = '4.2'
}

Start Eclipse (Oxygen.3a) on an empty new workspace. Ensure you have Greclipse 3.0.0.xx-201804162316-e47 and Buildship installed.

Do Import | Existing Gradle Project and select the /master folder as the root project. Keep all the default settings. Buildship will create two projects in your workspace, one named "myRoot" (mapping to /master) and the other one named "prjA" (mapping to /prjA).

Then try to open myRoot/build.gradle file from within Eclipse with the Groovy editor.

You'll get the following exception:

This started to happen recently, never had this problem until some time ago. I can't say when it started.

I suspect the problem may be related to the fact that "myRoot" lives inside a folder which is not called "myRoot".
