So when deploying to GAE with maven using OAuth it creates .appcfg_oauth2_tokens_java file in your home directory. This works great if you can deploy all your projects with one account. But what can you do when you wish to use different account for one of projects?
Can this file be project specific?
I don't wish to delete this file every time I want to deploy with different account.
You can prevent storing cookies with appcfg.sh --oauth2 --no_cookies.
For use with maven you can add the following config to your pom.xml:
<plugin>
<groupId>com.google.appengine</groupId>
<artifactId>appengine-maven-plugin</artifactId>
<version>1.9.9</version>
<configuration>
<oauth2>true</oauth2>
<noCookies>true</noCookies>
</configuration>
</plugin>

I don't have any experience in deployment and trying to deploy Frontend and backend together. I am able to successfully deploy the spring boot application.
I followed this tutorial and successfully generated a build.
Is it possible to deploy the frontend and backend together?
As mentioned in this GCP docs:
Use services in App Engine to factor your large apps into logical
components that can securely share App Engine features and communicate
with one another. Generally, your App Engine services behave like
microservices.
Deploying two apps written in different language on a same runtime in App Engine standard is not possible as you won't be able to run Javascript apps if the current runtime in your app.yaml is Java.
My suggestion would be to split your applications into separate services as mentioned in the docs.
Finally, if you insist on a monolithic approach, consider deploying your app to a custom runtime in App Engine flex. Refer to this doc. Do note that it requires a Dockerfile so you will have to manage the containerization of your apps.
We can deploy a spring boot backend application with react front end as a single JAR in GCP. I simply followed instructions in tutorial , Created an app engine in GCP and ran this command - gcloud app deploy ***.jar
You need to create the jar using maven and then run the command on that jar. It will deploy in gcp.

I have a react app with Spring backend. I have successfully deployed the Spring web app to Heroku, I can send http requests via postman to the endpoints and they work fine.
But I am unsure how I should allow the app on heroku to utilise the react frontend.
So far my structure is as below,
syftgolf
-.idea
-.mvn
-src
-target
-uploads-dev
-uploads-prod
-uploads-test
-.gitignore
-HELP.md
-mvnw
-mvnw.cmd
-pom.xml
-syftgolf.iml
-system.properties
Then in src I have
src
-main
--frontend //Front end react code
--java //Java code for Spring web app
--resources
-test
I am using the heroku CLI command git push heroku master on my route directory to deploy the app to heroku, this appears to then auto detact its a java app and then builds the app from there.
I am stuck though on how is the correct way to also build the react app? I read a post about building it first and adding it into the target/classes/static folder on my Spring app, but this folder doesn't appear to exist.
Which is the correct way to go about doing this please so when deployed, my app on heroku will also show the frontend stuff.
You need to tell maven where the react app resources are and where to add them in the output artifact. Use the maven resource plugin as follows:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<execution>
<id>copy-resources</id>
<phase>process-resources</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/classes/resources</outputDirectory>
<resources>
<resource>
<directory>/path/to/react/resources</directory>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
Just change the resource directory path to your react app build directory. The plugin will copy all the files in the directory to your artifact resources folder so spring will find them.
I am working on project where I used angular as frontend and spring boot as backend. I want to deploy my project on Sentora control panel. It requires only war files to deploy on server. I created war file of spring project but I dont know how to create war file of angular project. I used vs code for angular. I tried to find the way of creating war file for angular on internet but didn't find any solution. Should I need to import angular project in eclipse? Please someone tell me step by step solution to create war file of angular project.
Update: Error while deploying wabit.war file
I deployed simple spring boot project demo-0.0.1-SNAPSHOT and it started.
wabit.war file is deployed but it doesn't start. It gives error
FAIL - Application at context path [/wabit] could not be started
Why is this happening?
You can use maven for doing that.
Just add a pom.xml in you project with the following information.
With this configuration you will have to build your angular application in a file directory named dist.
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<!-- The Basics -->
<groupId>your.group</groupId>
<artifactId>projectName</artifactId>
<version>1.0.0</version>
<packaging>war</packaging>
<!-- Build Settings -->
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.1</version>
<configuration>
<webResources>
<resource>
<!-- this is relative to the pom.xml directory -->
<directory>dist</directory>
</resource>
</webResources>
</configuration>
</plugin>
</plugins>
</build>
</project>
After creating this file you will have to use the following command
mvn clean install
and the file will be created in the target/ directory
You can find more information on maven-war-plugins in the apache maven official documentation
Another solution is instead of creating a war file for your angular project just embed it in the spring boot war.
To do that
Just create your angular dist by ng build command.
Copy the contents of everything in that folder.
Go to your Spring Boot project and paste them inside a static package in the resources
directory. The path should be src/main/resources/static
Create and deploy the Spring boot war file and your angular will run as well.
This is how you directory of spring boot should look like
Whenever I deploy my app in Google App-engine Flexible, the version is based on the timestamp and each time new version will be created. In appEngine Standard we have:
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
<application>_your_app_id_</application>
<version>alpha-001</version>
<threadsafe>true</threadsafe>
</appengine-web-app>
I need that my app will be deployed always with the same Version name instead of creating new version. How can i do this goal in the same way as Appengine Standard.
If you are using maven with the new google cloud tools maven plugin to deploy your application:
<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>appengine-maven-plugin</artifactId>
<version>${appengine.plugin.version}</version>
</plugin>
you can define the version into your pom.xml adding the following property:
<properties>
<app.deploy.version>alpha-001</app.deploy.version>
</properties>
If you are using directly the gcloud executable form command line, you can specify the version adding the argument --version like this:
gcloud app deploy --version alpha-001
You can remove the <version> entry from appengine-web.xml.
I'm trying to make a simple base project to deploy a service I make using Jax-RS librarys to my Google app engine cloud space. The problem is that I don't know how to configure the plugin properly to not keep looking to a webapp directory under the target folder. The structure of the Jax-rs project puts the web.xml and all other WEB-INF files under the resources directory instead of a webapp directory. Is there a way to configure the maven plugin to deploy my already built and zipped up war file?
This is the error I see
[INFO] Updating Google App Engine Application Unable to find the
webapp directory C:\dev\gameTrunk\server\target\HOMMTG-server-1.0

and it goes on with all the appengine plugin targets...
This s my pom

Thats just the plugins part but its almost exactly the same as the guestbook example project except for the path for the WEB-INF directory
Currently there is no way to configure the appengine-maven-plugin to use a different directory for the war contents. It would be best though to probably create a multimodule build where one submodule just used the maven-ant-plugin to assemble the war directory and then run the plugin on that instead. I don't think we want to make that configurable in the plugin, since it doesn't really align with the maven-war-plugin, and configuring that would make it difficult to setup your project to use the maven-war-plugin seamlessly in the future.
The configuration you currently have for the war-plugin in your pom isn't necessary unless you want interpolation of the version number into the appengine-web.xml. I'm happy to help with setting up your pom so that the official Google App Engine Maven plugin works correctly for you.
(The instructions below apply to maven-gae-plugin, not appengine-maven-plugin.
Have I told you how much Google sucks in Open Source today?)
I think you must add in your maven-gae-plugin a property called appDir pointing to your webapp directory, like this:
<plugin>
<groupId>net.kindleit</groupId>
<artifactId>maven-gae-plugin</artifactId>
<configuration>
<appDir>PATH-TO-YOUR-BUILT-EXPLODED-WAR-PATH</appDir>
</configuration>
</plugin>
However, I must stress that changing the path in Maven produces undesirable results (you're mixing source and object code, your .ignore files will get messed up, and other weird things)
Note you STILL NEED your unpacked war somewhere. One way to achieve that is to create another .war project and use dependencies-unpack into it. See http://maven.apache.org/plugins/maven-dependency-plugin/unpack-dependencies-mojo.html
(reference: https://github.com/maven-gae-plugin/maven-gae-plugin/blob/master/maven-gae-plugin/src/main/java/net/kindleit/gae/EngineGoalBase.java)
(just in case, there is a JAX-RS based project for GAE I've wrote a while ago, and its open. See https://github.com/ipeirotis/ReadabilityMetrics/ for an overview)
