I assume he is using Cucumber-JVM 1.0.0 or 1.0.1, and the helloworld example.

I tried to reproduce this, but I don't have enough information about how to reproduce it. Things that would help to know:

• Exactly what files were generated.
• What cucumber version was used.
• Does it fail from the command line using Maven? (It didn't for me)
• Does it fail in Eclipse? (I haven't tried this yet)
• Does it fail in IntelliJ IDEA? (it didn't for me)

It might be a before/after hook failing like the other problems. I suspect it's related to the Exception Swallowing problem that I've been working on. This might be a different location, however.

Did you look at the source for the stack frames?

• https://github.com/cucumber/cucumber-jvm/blob/v1.0.1/core/src/main/java/cucumber/formatter/HTMLFormatter.java#L161
• https://github.com/cucumber/cucumber-jvm/blob/v1.0.1/core/src/main/java/cucumber/formatter/HTMLFormatter.java#L154
• https://github.com/cucumber/cucumber-jvm/blob/v1.0.1/core/src/main/java/cucumber/formatter/HTMLFormatter.java#L107

It looks like it's failing to copy one of the TEXT_ASSETS.

Heh, nope, Slow laptop is still booting. I was just noticing a pattern in the stack trace that seemed similar to the other failures. Looking at those parts, it's probably not related at all :)

We don't have environment info too like operating system. in would be null only if the resource can not be found: http://docs.oracle.com/javase/6/docs/api/java/lang/Class.html#getResourceAsStream%28java.lang.String%29

Hi, I got the same problem and I managed to get it right by remove @Cucumber.Options(format = {"pretty", "html:target/cucumber"}).
Step to create,
I have created the new project on eclipse and add jar file v1.0.1 as dependency
I create feature file and RunCukesTest.java file with the option above and got the error occur

Hi, I found the root cause. Actually I need to add another lib called cucumber-html to get this option right.

This should be fixed in 1.1.1.
