Groovy @Grab in DataMelt

[regrehan]

I'd like to be able to use Groovy with DataMelt. I find it easy (in other environments), to open a GroovyConsole and test out some code.

However, the GroovyConsole in DataMelt seems to have problems with the @Grapes/@Grab annotations. Whenever I try it, I get the following exception:
=========
java.lang.NoClassDefFoundError: org/apache/ivy/core/report/ResolveReport

at groovy.grape.Grape.grab(Grape.java:132)
at groovy.grape.GrabAnnotationTransformation.visit(GrabAnnotationTransformation.jav​a:311)
=========

The same code works fine "outside" of DataMelt.

Hello,

This Groovy issues was fixed for the beta version dmelt-1.4 posted on the download page.

When a make a file test.groovy :

Code:

@Grab(group='commons-lang', module='commons-lang', version='2.4')
import org.apache.commons.lang.WordUtils
println "Hello ${WordUtils.capitalize('world')}"

and run it as "dm_b test.groovy", it prints "Hello World"

best, Sergei[/code]

Hello, I do not think this feature can work. Dmelt includes "embedded" version of groovy. This version of Groovy does not include
ivy-2.4.0.jar.

So, it's really a bug in Groovy. By adding ivy-2.4.0.jar to Dmelt breaks Groovy console and other features..

I think Groovy team should fix this in their jar embedded version of groovy.
