Cleaning Google App Engine project in Eclipse - google-app-engine

I have a dumb question.
Do you know if cleaning a google app engine project in eclipse also generates the cloud endpoint client library ? or i have to generate it seperately ? Its just that every change im doing to an endpoint's signature takes forever to build and im wondering if im just doing the same thing twice.

Performing a clean does in fact generate the cloud endpoint client library if you have "Build Automatically" selected.
We need to change the behavior so that the regeneration is not done automatically, but lets the user know that the client libraries are out-of-date and gives them the option to update them.

How to mix Cloud Run and App Engine deployments in one project?

I have a Quarkus application already deployed on Google Cloud Run.
It depends on MySQL, hence there is an instance started on Cloud SQL.
Next step in my deployment process is to add keycloak. From what I've read the best option seems to be Google App Engine.
The approved answer in this question gave me some good insight of what needs to be done ... mostly.
What I did was:
Locally I made a sub-directory in the main project.
In that directory I added the app.yaml and the Dockerfile (as described here for instance).
There I executed the said two commands: gcloud init and gcloud app deploy.
I had my doubts about this set up and they were backed up by the error I got eventually:
ERROR: (gcloud.app.deploy) INVALID_ARGUMENT: The first service (module) you upload to a new application must be the 'default' service (module). Please upload a version of the 'default' service (module) before uploading a version for the 'morph-keycloak-service' service (module).
I understand my set up breaks the overall structure of the project but I'm not sure how to mix those two application with the right services.
I understand keycloak is a stateful application, hence cannot live on Cloud Run (by the way the intention is for keycloak to use the same database instance shared with the application).
So does any one know a more sensible set up, or what can I move in mine in order to fix it?
In short:
The answer really is in reading the error message (thanks #gaefan) - about the error itself it explains enough. So I just commented out the service: my-keycloak-service line in the app.yaml (thus leaving gcloud to implicitly mark it as the default one) and the deployment continued.
Eventually keycloak didn't connect to the database but if I don't manage to adjust the configurations that would probably be a subject to a different question.
On the point of project structure and functionality:
First off, thanks #NoCommandLine and #guillaume-blaquiere for your input!
#NoCommandLine the application on Cloud Run is sort of a headless REST API enabled backend. Most of the API calls are secured by keycloack. A next step in the deployment process would be to port an existing UI (React) client on the Firebase hosting (or on another suitable service - I'm still not completely sure which approach is best) and in order for the users to work with this client properly they must make an SSO through keycloak first.
I'm quite new to GCP and the number and variants of the available options are still overwhelming to me - one must get familiar with the nuances but I guess it takes time. So I'm still taking suggestions on how to adjust my project structure to fit better the services stack. Thanks!

Why does google app engine seem to use old code?

I've setup Google App Engine to run my AdonisJS API for my website. I update the code using the CLI for google cloud services ("gcloud app deploy"). I get a success message from the terminal, and I have checked both the cloud build and version number, and both are the most recent deployment. However, when I try to use my website, I get an error due to the API using old code and trying to access table columns from my database that no longer exist. I have downloaded the most recent cloud build file and checked the codebase within it and the updated code is there. I have also tried deploying multiple times, and it still is using the old code. Does anyone know why this is happening and/or how to fix this?
If you need more information, let me know. Thanks
ANSWER:
Fixed this a while ago, but wanted to update here just in case others ran into this. I discovered that when deploying to GAE through the command line, my build command wasn't running prior to the deploy since my script had an error, so it was uploading updated code, but not an updated build. So just make sure to run the build command prior to uploading to GAE and everything should work.
In console.cloud.google.com, go to your GAE project and check which version of your project is running I.e. which one is receiving traffic

Downloading App Engine source code

So it seems from a few SO questions I've seen that this is a problem among other users. Recently one of our head dev's left and I inherited a lot of his projects. One of which, is a website that what seems like lives on an app engine from google cloud platforms. From the App Engine documentation, to download source code you use the appcfg.py download_app command. Which I did, however the only results I get back from that call is:
Fetching file list...
Fetching files...
And then it just ends. No error message or any kind of message at all, and of course, it did not download the source code into the output dir I specified.
Scratching my head and looking at various SO posts, someone mentioned something about going into the google cloud vm directly and doing the same command, and to my surprise finding the same exact behavior that I did in my local terminal.
This made me realize it must be something else at play. I took a look at my versions tab in the App Engine dashboard on GCP. I see my instance running, it correctly says Serving and if I click the link it brings me to the website which loads fine. However, under Size it says 0 B which made me think perhaps this is why the download_app isn't downloading anything, because the version is 0 B?
What I'm trying to figure out is why it says 0 B for the version, when clearly the site runs fine and how I can get the source code for this. Here's a screenshot for reference
And screenshot of my terminal (local). Obviously I omitted the -A and -V flags, but they are correctly set and if I purposely make them incorrect I do indeed get an error message.
EDIT
Just so everyone is aware, I also made sure my user had the correct permissions. Owner, App Engine Owner... and some others. I don't think that's the problem.
When you deploy an App Engine Flexible application, the source code is uploaded to Cloud Storage on your project in a bucket named staging.<project-id>.appspot.com. You can navigate in this bucket and download the source code for a specific version as a .tar file.
Alternatively, you can find the exact Cloud Storage URL for your source code by going to Dev Console > Container Registry > Build History and select the build for your version. You'll find the link to your source code under Build Information.
One thing to note however is that the staging... bucket is created by default with a Lifecycle rule that deletes files older than 15 days automatically. You can delete this rule if you want so that all versions' source code is kept indefinitely.
In your case I believe that may not have helped since files may have been deleted already but it's worth knowing you can get the source code from there (source code isn't pushed to Source Repository by default, your developer had to configure it manually).
Posting this since none of the listed methods on the web didn't take me to the code (by June 2021)
Note: appcfg.py is deprecated by Google
You could try accessing your source code through;
Google Cloud Platform > Debugger > choosing the version of the
Application from combo at top.
This will list the files of that version on the left pane. There is no way to download code automatically but you can copy-paste the code.
Advice: Push your code to a Git repository to avoid this hassle next time.
Hope you will find this helpful.
In the developer console you can select the respective project and check:
on the Services page - which services, AKA modules - as they used to be (and still are) called in various places, you app has deployed
on the Versions page - which versions for each of the services are deployed
This information is what appcfg.py download_app expects. See also:
the various appcfg.py options using its --help flag
How do I download a specific service's source code off of AppEngine?
You can also access the deployed source code live (if everything else fails it could still be a last resort method to get the code, but tedious), see my answer to Google Cloud DataStore automatic indexing
Update:
I just now noticed in your screenshot that it's a flexible environment app. The appcfg.py docs are in the standard environment section, I suspect it's not applicable to the flexible environment, for which what's deployed is actually a docker image built during the deployment operation. From Deploying your application:
Deploy your app to App Engine using the gcloud app deploy
command. This command automatically builds a container image by using
the Container Builder service and then deploys that image to the
App Engine flexible environment. The container will include any local
modifications that you've made to the runtime image.
It might be possible to access the code on the actual GCE instance running the app, by connecting to the running instance and starting a shell in your app container, see Connecting to the instance

Cleanup Google Mobile Backend Starter

So I started to play with Google Mobile Backend Starter.
Now I want to clean this instance and anything that this starter thingy created into the project (e.g. task queues, data store, etc...)
How do we achieve this?
Is this done through some command line somewhere along the lines described in this page?
appengine-java-sdk/bin
EDIT: I should have made it clearer, I don't intend to delete the project. I just want to "clean" it and replace with my own application. Anyway, I ended up using the appengine SDK tools mentioned above (Updating and Managing a Java App). It was a long process, and tedious. It could be improved.
What I did:
Using the appengine SDK tool, downloaded the application first. It prompted me for a password. I had to create a new "App Password" entry in my Google account, since it didn't accept my "usual" Google password (e.g. GMAIL)
To clean the Scheduled Tasks, edit cron.xml so that no entries are left. A sample empty cron.xml file is shown in the documentation page. Run the update procedure of the SDK tool for cron jobs
To clean the Queues, use the same approach (queue.xml)
Clean DataStore by going to DataStore Admin page (if applicable)
Upload your new application (either thru SDK, or thru Android/Eclipse AppEngine plugin)
There will now be 2 (or more) versions of your AppEngine. If necessary, make your newly uploaded application, the default version. This is done in the Developer Console.
Check the instances as well. Remove if necessary
