Eclipse gradle plugin error importing project

Question

I'm trying to import a gradle project using the eclipse plugin 'buildship'. At the end of the eclipse import throws this error.

Synchronize Gradle projects with workspace failed due to an error connecting to the Gradle build.
Could not run build action using Gradle distribution 

'https://services.gradle.org/distributions/gradle-3.3-bin.zip'.

Could not determine the class-path for class org.gradle.tooling.internal.consumer.connection.InternalBuildActionAdapter.

Before importing project on eclipse I execute the 'gradle eclipse' command and everything goes well.

What I could do?

Thanks.

Answer 1

There was a bug in Gradle up to Version 3.4(?), where spaces within the build path were not allowed https://github.com/gradle/gradle/issues/1180

Because your build path contains a space because of "Eclipse Neon" it will fail.

Suggestions:

• Either update to the latest version
• or try to prevent the error by moving your eclipse neon installation so the path does not include spaces
