gherkin: StringIndexOutOfBoundsException in step

[Bludwarf]

Summary

Including capturing groups in another one in a step annotation RegExp makes cucumber throws StringIndexOutOfBoundsException.

Expected Behavior

Parse this line of cucumber :

Then reset x table on y except z

Where the except part is optionnal

Current Behavior

The line is well executed by cucumber but at the end of the feature (or after the end) it throws this exception :

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.041 sec <<< FAILURE! - in 
[...]
java.lang.StringIndexOutOfBoundsException: String index out of range: -Z

Where Z is the length of the parameter except

Possible Solution

Create a glue method like this :

@Given("reset (.+) table on ([A-Za-z_-]+)(?: except (.+))?")
public void doResetTableWithExcept(String table, String schema, String except) throws SQLException {

This way except keyword is not in a capturing group and makes cucumber work.

Steps to Reproduce (for bugs)

Create a glue method like this :

@Given("reset (.+) table on ([A-Za-z_-]+)( except (.+))?")
public void doResetTableWithExcept(String table, String schema, String exceptPart, String except) throws SQLException {

This way except keyword is in a capturing group and makes cucumber throw the exception.

@Bludwarf Please note you're using an old version of Cucumber. Try upgrading to a newer version. (Currently at v3.0.0 - which is not even a week old). Note that the <groupId>info.cukes</groupId> was changed to <groupId>io.cucumber</groupId> as of v2.0.0

Also, afaik this was fixed, see: cucumber/cucumber-jvm#1200 which is part of v2.0.0 and up (see changelog)

[mlvandijk]

Closing this issue, feel free to reopen if upgrading to v2.0.0 or higher doesn't fix it.
