5.9.0 Release Notes

Greclipse 5.9.0 was released on September 30th 2025.

New and Noteworthy

Support for new versions of Groovy

• Groovy 5.0.1

• Groovy 4.0.28

  📋 The new antlr4-based Parrot Parser is disabled by default. To enable it, add -Dgroovy.antlr4=true to your eclipse.ini file after the -vmargs line or add a compiler config script to your project with configuration.pluginFactory = org.codehaus.groovy.control.ParserPluginFactory.antlr4(). Please note that parser recovery is not implemented for the Parrot Parser, so your editing experience may be sub-par in this mode.
