[ERROR] Don't resolve expressions during indexing!

[Alex-Ph]

Compiling this feature:

Feature: Test
Scenario: Preparing bug2
When I need two parameters "a" and "b"
args.first should not be args.second
Then I do nothing special with "a" and "b"
args.first should not be args.second

Scenario: Trigger bug
When I try to reuse the THEN above the Feature logs an error to console "a" "b"
args.first should not be args.second
Then I do nothing special with "a" and "b"

results in an error: [ERROR] Don't resolve expressions during indexing!

The build success but this error is logged to console

[sebastianbenz]

Does the generated code work as expected?

[Alex-Ph]

Yes the code works as expected inside eclipse. Only when I compiling the feature through maven I got the error log above

[gzunino]

This is also affecting my build, same error building with maven.
