I am looking for a similar functionality like:
heroku logs --tail
but for Google Appengine. Does anyone know of its existence?
gcloud app logs tail is now in generally available!
https://cloud.google.com/sdk/gcloud/reference/app/logs/tail
Have you seen gcloud preview app logs read?

I have just deployed an app on Google App Engine using gcloud app deploy and I get a warning such as below:
WARNING: There is a dependency on App Engine APIs, but they are not enabled in your app.yaml. Set the app_engine_apis property.
So what I did was to include app_engine_apis: true in the app.yaml, saved it, and proceed to gcloud app deploy again. However I'm still getting the same warning. What am I missing?
I fixed the warning by running:
google beta app deploy
instead of
google app deploy
I got the fix from this document. I believe it's necessary because at the time of this answer the migration of the python2 app_engine_apis to python3 isn't complete.
Is there a way to update files for google app engine. I deployed the google app engine. I want to update the files on the google cloud app engine but I am unsure how to do this. When I am following the django google app engine.
How I try to fix this problem is by "re-deploying " but I receive a "too many files error" I am unsure how to fix this. How do I change the source code in the google app engine with the correct code?
You update the files on App Engine by doing this command in your project root
gcloud app deploy . --version YOUR_VERSION_NAME --project YOUR_PROJECT_NAME
But it sounds like that's what you're trying to do but you're getting a "too many files error"
I think the limit is 10,000 files. There most likely is a rogue directory in your project root that is causing the problem.
In your app.yaml you can add a skip_files section for files that should not get uploaded to App Engine.
skip_files:
- ^\.git/.*
- ^node_modules/(.*/)?
https://cloud.google.com/appengine/docs/standard/python/config/appref#skip_files
While I was deploying my google app engine project (Java) using gradle appengineDeploy my internet connection was interrupted.
I re-deployed the project. Although the console said BUILD SUCCESSFUL, the app engine instance no longer works. No matter how many times I re-deploy or update my application, the logs show nothing but errors:

Is there some way for me to clear out the partial build (or whatever there may be) in google app engine?
I tried deleting all versions and instances (you cannot delete them all, it won't let you delete the serving one).
I tried increasing the version number in appengine-web.xml.
I tried gradle clean.
I tried disabling and enabling the application in the google cloud console.
No luck.
One idea I have is maybe if I can somehow force all the files for the app to be uploaded again? Because with gradle appengineDeploy only the changed files get uploaded.
EDIT:
I managed to fix one part of this by upgrading classpath 'com.google.cloud.tools:appengine-gradle-plugin:2.2.0' in my gradle to the latest version. (Felt kind of hackish to do that and not reliable in the future if this happens again.) Maybe this flushed whatever was in app engine or something by doing that. I still have one problem remaining:
I am using the firebase admin SDK to send firebase cloud messages (authenticated with a .json credentials file) like this:
FirebaseMessaging.getInstance().send(msg);
When I do I am getting this error:
com.google.firebase.messaging.FirebaseMessagingException: Unexpected
HTTP response with status: 401; body: null
Which is strange because other parts of the firebase admin SDK are working (like writing/reading from firestore).
So there is still something weird going on and I think it has to do with the fact that as I was uploading my google app engine project the connection was interrupted.
EDIT 2:
Here is something interesting: When I deploy my application using gcloud app deploy appengine-web.xml the application again will not work. Deploying with gradle appengineDeploy does though. I also noticed that the size of the application is shown as much smaller in the GCP console when deploying with gcloud app deploy appengine-web.xml. So something is messed up here. I tried looking up some sort of gcloud command to clear cache? Or something like that but no luck.
EDIT 3:
Additional Info:
My app was already deployed and working before the failed attempt. I changed one small piece of code in a function and upon uploading the app, the connection was interrupted because the internet went out.
I am on app engine standard environment.
I am deploying my application from the macOS terminal and using android studio to develop.
I have tried the stopPreviousVersion promote and version configs in gradle (actually the first two are true by default and version gets auto-generated if you do not set it).
Running gcloud app deploy appengine-web.xml --verbosity=debug shows a lot of sensitive information but one thing I am seeing is all the files in WEB-INF are being skipped:
DEBUG: Skipping upload of [WEB-INF/....
INFO: Incremental upload skipped 100.0% of data
DEBUG: Uploading 0 files to Google Cloud Storage
DEBUG: Using [16] threads
So perhaps files are not all being uploaded? This SO post raises a similar problem but has no solution: stackoverflow.com/q/42137452/3075340
It's weird but when I do gcloud app deploy, the app won't work at all. There are run-time errors all over the place. Doing gradle appengineDeploy fixes that but I still am having the firebase-admin issue.
To actually answer your question, GAE uses a staging bucket to cache files.
You can delete this bucket, and it will get recreated next time you try to deploy.
The bucket is always named staging.[PROJECT-ID].appspot.com. It should show on the buckets overview page
Just to be clear, I'm not anywhere near sure that this will actually resolve your issue, but this will most definitely clear whatever files GAE cached
Here there was a discussion on a, more or less, similar issue on App Engine from last year.
You can use it as a source of inspiration to fix your current issue, because I think they are really similar as a concept. From there I think it may worth trying to put the appengine-api-1.0-sdk-1.9.63.jar ( or whatever your version is ) file under WEB-INF/lib.
It the same post there were some guys who found out the there was a problem with gcloud v194 and switching to another version fixed the issue.
Here there is a similar issue which was resolved by upgrading the gcloud tool.
Anyhow, this behaviour is not normal and things should not work like this. You can try to find a workaround, but my recommendation is to report the issue and let an App Engine engineer taking a look over it. There are good chances to be something internal.
Ive just upgraded the Google App Engine Launcher (for PHP) and now I'm getting this error message.
Any ideas what why that ocurred and how to fix it?
UPDATE1: right now it is only working in console like this:
"C:\Program Files (x86)\Google\google_appengine\appcfg.py" "update" "D:\route\to\application"
And I can't find the way to update the parameter in the Google Engine Launcher. Any thoughts?
UPDATE2: ok, it seems that the issue has to do with the migration to oAuth2. So, the new question is: how can I make the Google Engine no to use "--passin"? Because I uninstalled (and remove any trace of it) and then reinstalled, but it insist in using the "--passing" parameter, making it completely useless.
UPDATE3: the issue was that I was using Google SDK and updated the Engine using "GoogleAppEngine-1.9.24.msi". And it was not updating the shortcut, so I was still using some data from the SDK.
Solution: remove the Google Cloud SDK and install again. Then install the App Engine. And it worked.
Solution: remove the Google Cloud SDK and install again. Then install the App Engine. And it worked.
I want to download the code from google app engine.
And I installed python, google engine sdk and executed this command
appcfg.py download_app -a ...
and I typed my mail address and password...
but it says
Error 403: ---
You do not have permission to download this app version
What do you think is the problem? Please help me with this.
I am stuck with this like all day but can't find the solution.
I encountered the same problem (Mac OS, running AppEngineLauncher).
Noticed that no apps were running in GAEL.
Running one of the apps in GAEL (earlier version of the same one - could be a coincidence) seemed to make a difference - it started the download, but then halted.
Then I ran appcfg list_versions on that app, followed by download_app.
That seemed to do the job - download continuing as I write this.
On a guess, appcfg got hazy about its security context. YMMV.
Check:
Only the developer who uploaded the code and the application owner(s) can download it. If anyone other than these parties attempts to download the app, they'll see an error message like the following: Error 403
https://developers.google.com/appengine/docs/python/tools/uploadinganapp#Python_Downloading_source_code
or your app have set permanently prohibit code downloads. Check on page: https://appengine.google.com/deployment/codelock?app_id=your_app_id&to_forward=/permissions?app_id=your_app_id
Adding flag --no_cookies worked for me.
