[jira] [Resolved] (GROOVY-5320) groovyc ant task cannot compile Servlet using Java EE 6 reference API libaries (results in ClassFormatError Missing Code attribute)

["Eric Milles (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-5320?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Milles resolved GROOVY-5320.
---------------------------------
    Fix Version/s: 2.5.0
       Resolution: Fixed

Starting in Groovy 2.5, classes are resolved through ASM before traditional class loading.  This allows {{groovyc}} to compile against this {{servlet-api}} artifact.

Tested against Groovy 1.8.6, 2.0.8, 2.1.9, 2.2.2, 2.3.11, 2.4.21 and 2.5.16

> Compiling a simple servlet against the Java EE 6 reference APIs results in a groovyc compilation failure. I have attached a project with both a Java Servlet and a Groovy Servlet.
> The Java compiler works ok but the groovyc fails. Using Maven's eclipse-groovy-plugin also works ok. It seems that the groovyc compiler is introspecting the class in a different way than the maven eclipse-groovy-compiler.
