NOTE Not sure what helped, but this get resolved. I did 2 things:- 1.I ran gradle command from terminal in workspace of eclipse. 2.Updated Buildship gradle integration from eclipse ide.

You have Eclipse Oxygen.1 (4.7.1), but Java 9 is only supported since Oxygen.1a (4.7.1a). — howlger, Nov 28 '17 at 08:42
I have Oxygen.1a (4.7.1a), but am facing the same error. Were you able to find a resolution? — alpha_ulrich, Dec 03 '17 at 13:15
Tried many other ways like https://stackoverflow.com/questions/18487406/how-do-i-tell-gradle-to-use-specific-jdk-version, this one works like a charm. — Vetro Watt, Oct 23 '19 at 18:02

The Buildship team has released a milestone 2.2 build that fixes this issue.

You can either install the milestone 2.2 in eclipse. Help > Install New Software... > Work with: http://download.eclipse.org/buildship/updates/e47/milestones/2.x > Select most recent version > Finish

Or you can wait until the official 2.2 release of Buildship and update the Buildship plugin.

You have to install the Buildship from Eclipse Marketplace and also changed the build script (to fix the gradle eclipse plugin with unexpected behavior to Java 9):

eclipse {
    jdt.file.withProperties { props ->
       props.put('org.eclipse.jdt.core.compiler.codegen.targetPlatform', '9')
       props.put('org.eclipse.jdt.core.compiler.source', '9')
       props.put('org.eclipse.jdt.core.compiler.compliance', '9')
    }
    classpath.defaultOutputDir = new File(buildDir, "classes/main")
}
