ANN: Gradle GAE Plugin

[Benjamin Muschko]

Hi,

Some people might already use Gradle for their Gaelyk builds so this
might be interesting to you. I implemented a Gradle Google App Engine
(GAE) plugin (http://bit.ly/fdy5fg) that provides tasks for uploading,
running and managing of Google App Engine Java projects. The
documentation describes setup and convention properties in detail. The
plugin is not limited to plain Java GAE projects. It can also handle
Gaelyk projects - please refer to the FAQ section. In particular the
plugin defines the following tasks:

- gaeCronInfo: Verifies and prints the scheduled task (cron)
configuration.
- gaeEnhance: Enhances DataNucleus classes by using byte-code
manipulation to make your normal Java classes "persistable".
- gaeLogs: Retrieves log data for the application running on App
Engine.
- gaeRollback: Undoes a partially completed update for the given
application.
- gaeRun: Starts a local development server running your project
code.
- gaeStop: Stops the local development server.
- gaeUpdateCron: Updates the schedule task (cron) configuration for
the app, based on the cron.xml file.
- gaeUpdateDos: Updates the DoS protection configuration for the app,
based on the dos.xml file.
- gaeUpdateIndexes: Updates datastore indexes in App Engine to include
newly added indexes.
- gaeUpdateQueues: Updates the task queue configuration (queue.xml) in
App Engine.
- gaeUpload: Uploads files for an application given the application's
root directory. The application ID and version are taken from the
appengine-web.xml file.
- gaeVacuumIndexes: Deletes unused indexes in App Engine server.
- gaeVersion: Prints detailed version information about the SDK, Java
and the operating system.

Please let me know if you have any feedback or feature requests. I'd
be happy to improve the plugin.

Cheers,

Ben

Hi Steven,

Have a look at the README.md file on Github: http://bit.ly/fJzvvo. If
you need more information like a full build.gradle please let me know.

Sorry I'm really new to gradle and git and just cant add one and one together on this.

Is there an example build.gradle file for gae?

Kind regards,

Steven

[Steven]

Sorry, got it working. However I cant get the password (or
gaePassword) parameters to work. The gaeUpload task still always
prompts for a password.

Here is my config:
gae {
appcfg {
email = "baker.s...@gmail.com"
gaePassword = "xxxxxx"
password = "xxxxxx"
passIn = false
}
}


Any ideas? Is this part just not done yet?

[Benjamin Muschko]

Steven,

Great! The version you are using (0.2) doesn't have the convention
property "password" yet. It has been implement on "mainline" so to say
but didn't get released yet. There's another feature I want to build
before I release version 0.3 including that property. Version 0.3 will
probably be released within the next two weeks. If you really, really
need the property right now you can download the source and build the
version yourself.

Thanks,

Ben

Ben,

I had to add a couple things that weren't in your README on github ...
first, to define sourceSets { main { groovy { ... } } } - I had to
apply plugin: 'groovy' - the War plugin only extends the Java plugin,
apparently ...

Then, to get the .gdsl file include from src/, I had to define a
sourceSets { main { resources { srcDir 'src' } } } - not sure if the
'groovy' sourceSet by default only picks up *.groovy files?

I haven't customized anything in my workspace from unzipping the
Gaelyk template project (0.6.1). I'm using Gradle 1.0-milestone-1.
Installed the locally compile (from GitHub clone) gradle-gae-plugin
(v0.2-7-gac7590d) to my local maven repo and added mavenLocal() to my
repositories instead of pulling the older release version from GitHub.

Awesome work on this plugin!!

Hi Brice,

Thanks for your feedback. Most of the things I simply assumed the
Gradle user would already know. Especially, when it comes to applying
and configuring the Groovy plugin. The .gdsl is only used by IDEs
(describes the Gaelyk DSL) and is not required to be included in the
WAR file. However, if you have Groovy classes sitting in src then
you'd want to set the Groovy sourcedir. I will add all of that in the
next version of the plugin.

OK - or just add a couple lines in the README, wasn't too hard to figure out, but this was my first go at using Gradle for a Gaelyk app. Since a Gaelyk app will contain Groovy source, of course, it would make sense to have a Groovy sourceSet.

Ben -

Am I missing something? When I do gaeRun, I get the output below, but I don't think Jetty is actually running ...

be sure to upgrade to the latest gae jdk if you are using OSX and JDK 1.6.0_24

Well, yeah - I think I have that. 1.4.3, just grabbed that last night. I had 1.3.8 in my path previously and no difference in behavior. I'm not getting any errors anywhere that I can see .. is there a log hiding somewhere? I'll check my Console.app to be sure ...

yea, since the OSX JDK 1.6.0_24 update, gae jetty would crash on startup.

the new GAE SDK fixes that.

[Brice Ruth]

Newer than 1.4.3, then?

Just realized I have appengine-1.4.3 in my path & APPENGINE_HOME, but 1.4.2 is what's configured in Gradle. Rebuilding ...

Steven,

Version 0.3 of the plugin got released. You will now be able to set
the password. Please refer to the documentation for more information.

Thanks heaps. This has greatly improved our ability to deploy.

Hello Ben,

I would love an example build.gradle file.

I've only toyed with gradle and I love it. However, I'm trying to see how to:

- Build (I've done that by hand actually, but I like the idea of your plugin much better)

- Run from the command line (your plugin does that)

- Create an eclipse project (nice to have)

If I can only run my unit tests in eclipse and use the command line to push the app out to the interwebs, that's cool.

The problem I have is, being a relative gradle noob, your readme seems to be missing some stuff for such a brain as mine)))

Give me a simple example, however, and I'm all over that.

I know this is /late/ compared to the timeline of this tread, but who knows.

In any case, thanks for building this plugin.

Brett

Brett,

I guess this has been answered by my Twitter responses? Let me know if
you need additional help.
