Re: Official Docker Groovy images

[Keegan Witt]

I'm preparing to update for 2.4.9 and am considering two significant
changes to the initial image.  First, to create a volume to prevent Grape
caches from being put into downstream images (PR #6
), and using a user other
than root for the container (PR #7
).  I'm pretty sure I'm
going to do #6, should be pretty safe.  But I'm still weighing #7.  I wanna
get that decided this week so that we pick something and stick with it, to
avoid breaking anything later.  Please weigh in if you have any opinion.

Re: Override a method without knowing its parameters

[Douglas Mendes]

Answering my own question:

It can be done if the metaClass is an ExpandoMetaClass. Like this:

expandoMetaClass.registerInstanceMethod(
new TransformMetaMethod(originalMetaMethod) {
@Override
Object invoke(Object object, Object[] arguments) {
println "Done! Method overriden!"
super.invoke(object, arguments)
}
}
)

Anyway, in grails it didn't work (it kept calling the original method). Had
to use an AST.

Hi.

How can I properly override a method given a java.lang.reflect.Method and
its respective MetaClass?

I know that can be achieved by overriding the MetaClass's *invokeMethod *but
I can't do that (even if I could, would like to avoid).

Pseudocode:

*void doAnOverride(MetaClass metaClass, Method method) {*
*metaClass."${method.name }" = { args ->*
*println "done"*
*}*
*}*

Thanks,
Douglas
