That project is unusable. Its deployment doc links to a replacement project's non-GWT page. Is there a simple GWT/Endpoints tutorial that is complete and works with the current infrastructure? Preferably with Android Studio, though I'm learning to adapt Ant build files to Gradle (after years of not using Ant).
* Details: I cloned its googlearchive/appengine-gwtguestbook-namespaces-java project from its current location https://github.com/googlearchive/appengine-gwtguestbook-namespaces-java and imported it into Android Studio. I downloaded gwt-2.8.0 . I added a build.gradle consisting of ant.importBuild 'build.xml' and added to build.properties the correct values for gwt.home and appengine.home . Then from the commandline I executed gradle build . I had to add to the gwtc target JVM arg -Xss16M because the build ran out of memory, but it built OK. It built a lot of classes, libraries, a war directory. gradle runserver started a server on localhost and it seemed to execute a guestbook messaging system OK. But how to deploy it to App Engine? The README.md file says: > You can then upload your application following the instructions described > in the Google App Engine Java Runtime SDK documentation: > http://code.google.com/appengine/docs/java/gettingstarted/uploading.html But that code.google.com URL redirects to https://cloud.google.com/appengine/docs/java/gettingstarted/deploying-the-application?csw=1 "App Engine > Documentation > Java Deploying the Application In this final part of the Guestbook tutorial, you learn how to deploy your application, including generating the Google Cloud Datastore indexes required for deployment. This page is part of a multi-page tutorial. To start from the beginning and see instructions for setting up, go to Creating a Guestbook." That doc is not consistent with the original project. It doesn't refer to GWT at all. It says that running the app on the dev server (ie. gradle runserver ) would generate indexes in datastore-indexes-auto.xml but that file contained a comment indicating my gradle runserver invocation wrote indices, but the XML contained only "<datastore-indexes/>". Maybe the indexes aren't necessary. But how to deploy it? Android Studio's menu Build > Deploy Module to App Engine... gives only 'This project does not contain any App Engine modules. To add an App Engine module for your project, open “File > New Module…” menu and choose one of App Engine modules.' Menu File > New > New Module... shows a Google Cloud Module option, but it wants a "Client module" value, and the dropdown is empty. The "App Engine Java Endpoints Module" page linked from the new module dialog is the Github GoogleCloudPlatform/gradle-appengine-templates/HelloEndpoints page for adding an Endpoints backend to an Android app. Again, nothing about GWT. FWIW inspecting the actual Java source showed most classes were unresolved, such as EntryPoint and the "core" part of "import com.google.gwt.core.client.EntryPoint;" etc. I suppose the build converts the Java to Javascript against the GWT libraries without having the necessary dependencies for the Java to build targeting the JVM.
