• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 2.5.3, 2.5.4, 2.5.5, 2.5.6, 2.5.7
• Component/s: groovy-jdk
• Environment: jdk1.8.0_212, macos 10.14.5
• Assignee: Unassigned

Description

Groovy 2.5.3+ ConfigSlurper throws a MissingMethodException when parsing a groovy configuration script that contains a node named "main".  In prior versions of groovy (tested with 2.4.17, 2.5.0, 2.5.1, 2.5.2), such a configuration script parses the 'main' config without incident.

You can use this repo to reproduce the issue.

  main {     

    prop1 = 'one'

    }

}
