Answer 1

I got this error while upgrading the Cucumber version in my Maven based project.

Turn out that I updated <artifactId>cucumber-java</artifactId> version from 1.1.5 to 1.2.4, but I didn't update <artifactId>cucumber-junit</artifactId> - it was still on 1.1.5.

On the moment I updated both to the same version, this error was gone.

Answer 2

Class file that your code depends on and it is present at compile time but not found at runtime. Look for differences in your build time and runtime classpaths.

Answer 3

将cucumber-core，cucumber-java和cucumber-junit更新为相同的版本（我使用的是1.1.5版本）。问题已为我解决。
