Gaelyk 2.0 bug?

[Alex Garrett]

With the new Gaelyk2 I can no longer use

request.myVar = "blah"

in my groovlets.

Works in dev, but not on a gae server!

To reproduce what happens, I built the gaelyk template app
with datetime.groovy modified

request.setAttribute 'datetime', new Date().toString()
request.testMe = true

and get the same exception

groovy.lang.MissingPropertyException: No such property: testMe for
class: org.mortbay.jetty.Request
at
org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:
50)
at
org.codehaus.groovy.runtime.ScriptBytecodeAdapter.setProperty(ScriptBytecodeAdapter.java:
482)
at datetime.run(datetime.groovy:6)

Any hints before I change some 191 usages in my app, to get around
this

Well I have made some changes and have the template project going now.

i.e request object does work.

Now to work out what is different...

In the process I changed from Oracle JDK 7 to OpenJDK, but no idea if this is a contributor!

Sadly I'm still dead in the water.

I forgot I was only testing locally, where it works.

As soon as I use the proof (template project), 

and access the request object on a gae server, 

it throws the exception!

my code extensively uses the request object in goovlets and templates too.

If there are no answers, I have to find a way to back out of this upgrade.

HI Alex,

I've found the problem,

the template project is missing following line

classpath 'org.gradle.api.plugins:gradle-gae-plugin:0.8'

in build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'org.gradle.api.plugins:gradle-gaelyk-plugin:0.4.1'
        classpath 'org.gradle.api.plugins:gradle-gae-plugin:0.8'
        classpath 'org.gradle.api.plugins:gradle-gae-geb-plugin:0.3'
    }
}

Thanks to this missing dependency, old fatjar plugin was used which wasn't capable of merging Groovy 2.0 extension module descriptors

Please let me know if it helps you we'll update the template as soon as possible

Cheers,

Vladimir

When I run Gaelyk locally I see

     public void javax.servlet.ServletRequestWrapper.setAttribute(java.lang.String,java.lang.Object)

as a method on the 'request' object. In fact I see lots of ServletRequestWrapper methods.

But on gae I only see the underlying jetty implementation

     org.mortbay.jetty.Request.setAttribute(java.lang.String,java.lang.Object)

So looking at the template project and search for ServletRequestWrapper, it comes up in

    servlet-api-2.5.jar

    appengine-api-1.0-sdk-1.8.0.jar

and 

    template-project-2.0.jar

Hmm, is this a build problem, classpath, loss of dynamic magic, or?

[Vladimír Oraný]

actually the gae gradle plugin is still using old fatjar version so the buildscript dependencies config closure should look like following

buildscript {

    repositories {

        mavenCentral()

    }

    dependencies {

        classpath 'org.gradle.api.plugins:gradle-gaelyk-plugin:0.4.1'

        classpath 'org.gradle.api.plugins:gradle-gae-plugin:0.8', {

            exclude module: "gradle-fatjar-plugin"

        }

        classpath 'eu.appsatori:gradle-fatjar-plugin:0.2-rc1'

        classpath 'org.gradle.api.plugins:gradle-gae-geb-plugin:0.3'

    }

}

Hi Vladimir

I've rebuilt my project...

And... 

It now runs on the app engine servers :---)

I have a lot of code to test now, but it's great to see it all running

on our test server instance

fingers crossed, and I'll keep you posted as I further test Gaelyk 2

regards 

Alex

Cool, let us know your progress! The updated template project should be available later today.

[Guillaume Laforge]

The updated template project is now up:

http://dl.bintray.com/glaforge/gaelyk/gaelyk-template-project-2.0.1.zip?direct

We've removed the old template.

And we'll update the link on the website in a short moment.

The website is updated too. Please take a note that if you're updating your app to 2.0 you also need to update your build script as follows:

buildscript {

    dependencies {

        classpath 'org.gradle.api.plugins:gradle-gaelyk-plugin:0.4.1'

        classpath 'org.gradle.api.plugins:gradle-gae-plugin:0.8', {

            exclude module: "gradle-fatjar-plugin"

        }

        classpath 'eu.appsatori:gradle-fatjar-plugin:0.2-rc1'

        classpath 'org.gradle.api.plugins:gradle-gae-geb-plugin:0.3'

    }

}

fatjar plugin of the version at least 0.2-rc1 is needed to handle the Groovy 2.0 extension modules descriptors handled properly.

[Marcin Erdmann]

We should probably release new versions of gradle-gae and gradle-gaelyk
plugins so all that ovewriting of fatjar plugin is not necessary. This
is all too complex for the users and in the ideal world they want to
only specify one dependency in their buildscript block - the one for
gradle-gaelyk-plugin.
