GAE: No longer able to update my Gaelyk project due to appcfg losing support

Recently tried to update my Gaelyk project (yes, it's old, but it works well and I still use it), but Google App Engine will no longer accept the update. The error message returned is "Deployments using appcfg are no longer supported. See https://cloud.google.com/appengine/docs/deprecations". The thing is, I never used appcfg to deploy my application; I used Gaelyk and Gradle. But obviously Gaelyk must have used appcfg under the covers.

I did download the replacement Google Cloud SDK, but this new tool is not similar at all to how Gaelyk and Gradle worked. Is there anything I can do to get Gaelyk to work anymore? Or is Gaelyk just dead and I need to rewrite my application (like in Node.js or something instead of Groovy).

Solution

  • I can confirm that Serge's answer on the Gaelyk Groups site works; the same procedure that he figured out also worked for me. To summarize:

    1. Run gradlew appengineRun as run previously with Gaelyk.
    2. Copy all jar files inside the build\exploded-app\WEB-INF\lib folder into a \src\main\webapp\web-inf\lib folder (for me the new lib folder did not exist previously).
    3. To deploy, use the new required gcloud tool, and instead of running gradlew appengineUpdate (which fails now), instead run gcloud app deploy appengine-web.xml where that XML file can be found in your webapp/WEB-INF directory. I navigated to that directory to run the gcloud command, but you can use a relative path there if your working directory is elsewhere. (There are a number of optional flags associated with the gcloud app deploy command, but I didn't need any of them.)
    4. Serge needed to use these instructions to convert datastore-indexes.xml to index.yaml and run gcloud app deploy index.yaml, however, I didn't need to do this because I had no datastores.
