I'm trying to build an instance of start.spring.io to use it in an air-gaped network. I have been working on it for three weeks and still I don't understand well what to do.
I have cloned start.spring.io from GitHub in a host connected to Internet.
There I can build the application without errors:
./mvnw clean install -DskipTests=true
Then if I true to run the application (../mwnw spring-boot:run from the start-site directory), I get the following error when the application starts, I mean is not an error trying to generate a project, and the application dies:

So, I am not adding any special dependencies or initilializr dependencies other than those already included in the project. I use Java 17 from Bell Soft.
I am not about the Spring Boot version but I haven't modified anything in the project. The pom file in the top directory includes:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.5</version>
</parent>
About my dependencies I am using the initializer-bom:0.20.0-SNAPSHOT. I have also tried with other versions like 0.13.0 and 0.12.0 but the build fails in both cases for the start-site:

I wonder if this effort makes sense. If I manage to build the application, will I be able of generating code or does the application connect to somewhere else to retrieve the data required to generate the code?
I would appreciate any hints. Thanks
I will write my (potential) answer here, even though I don't really think that is a real answer but too big to make it as a comment.
My setup:
Amazon Coretto JDK 17 https://docs.aws.amazon.com/corretto/latest/corretto-17-ug/downloads-list.html (it is not JDK 17 from Bell Soft)
Windows 11 Home
So I went to https://github.com/spring-io/start.spring.io and cloned it.
git clone https://github.com/spring-io/start.spring.io.git
Then I went in the root directoy of the cloned project and ran following command:
./mvnw clean install
Here I got some errors while running the tests, but this shouldn't be way too tragic - I think they failed for me, because it tries to run some gradlew commands but they do fail, because I don't have Gradle installed on my PC, as I am always using the Gradle Wrapper.
Then I started the Spring Boot Application.
cd start-site
../mvnw spring-boot:run
The Spring Boot Application started:

Could it maybe be your JDK? I mean the JDKs are similar but not the same... And you also asked:
I wonder if this effort makes sense. If I manage to build the
application, will I be able of generating code or does the application
connect to somewhere else to retrieve the data required to generate
the code? I would appreciate any hints. Thanks
I personally think, it could make sense but - as soon as I generated a project on my own Spring Initializr, I watched the console of the Spring Boot Application and could see the following log:
Fetching Spring Boot metadata from https://spring.io/project_metadata/spring-boot
So it looks, like this thing actually fetches data from the internet, now I don't know what options you have but I have two in mind.
You could try to fork the GitHub Project and try to remove this network call (if this is really the only one) - I couldn't see anything more in the logs atleast... The actual response of the Call looks pretty simple though:
{"id":"spring-boot","name":"Spring Boot","projectReleases":[{"version":"3.0.1-SNAPSHOT","versionDisplayName":"3.0.1-SNAPSHOT","current":false,"releaseStatus":"SNAPSHOT","snapshot":true},{"version":"3.0.0","versionDisplayName":"3.0.0","current":true,"releaseStatus":"GENERAL_AVAILABILITY","snapshot":false},{"version":"2.7.7-SNAPSHOT","versionDisplayName":"2.7.7-SNAPSHOT","current":false,"releaseStatus":"SNAPSHOT","snapshot":true},{"version":"2.7.6","versionDisplayName":"2.7.6","current":false,"releaseStatus":"GENERAL_AVAILABILITY","snapshot":false},{"version":"2.6.14","versionDisplayName":"2.6.14","current":false,"releaseStatus":"GENERAL_AVAILABILITY","snapshot":false},{"version":"2.5.14","versionDisplayName":"2.5.14","current":false,"releaseStatus":"GENERAL_AVAILABILITY","snapshot":false},{"version":"2.4.13","versionDisplayName":"2.4.13","current":false,"releaseStatus":"GENERAL_AVAILABILITY","snapshot":false}]}
You allow explicitly the URL https://spring.io/project_metadata/spring-boot to fetch data inside of your Air Gap Network (I don't know if this is viable though)
I hope this helps a bit?
There are many dependencies that start from the initializer for spring-boot. If you try to build within an air-gapped network, you will not have access to maven's repository for the dependencies. Try building the package outside the network, and capture the libraries required. Look to your ~/.m2/ folder for the copies of the libraries needed. I would recommend setting up a Nexus repository, and it will capture the libraries as you need them from an open network which you can then use on the air-gapped network.
If this is a secured network, you'll have to have all those files vetted and scanned before you can get them into the air-gapped network. Plan for this.
As you add additional annotations or dependencies, you will have to get them from maven central again. It's not ideal, but you might find someone who setup a project to include all spring-boot dependencies for just this situation.
Also, use the STS dev environment, and build your spring-boot to run with included libraries.
I have created a hilla app using this:
npx #vaadin/cli init --hilla --auth hilla-with-auth
Works fine!
Now I am trying to add that to an existing spring boot application, but I am having issues with Vite not starting as it should. No exception. No help in the debug output.
I have added:
relevant files in the root (package.json, vite.config.ts, etc.)
vaadin-featureflags.properties in resources folder
hilla dependencies in pom.xml as well as the build plugin
hill annotations to my application class (#Theme, #PWA) and made it extends SpringBootServletInitializer implements AppShellConfigurator
But even if everything seems to be initialized correctly, Vite does not start. Can anyone guide me in the right direction?
This is the most relevant output log:

I see issues in the Spring cloud config server (Springboot) logs when connecting to the repo where configs are stored. I'm not sure if it's unable to clone because of credentials or something else (git-upload-pack not permitted). Any pointers to this would be great.

502 - Web server received an invalid response while acting as a gateway or proxy server.
There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.

:( Application Error
If you are the application administrator, you can access the diagnostic resources.
is there any additional steps I need to expose port 8080 and path /WebGoat?
To expose port 8080 on the app service see this thread.
As for the path you should install the app under site/home/wwwroot. Check configuration -> Path mappings to see the virtual directories.
I ended up getting this log as a result of running my Spring Boot App with a jsp.

If your application is running on WebSphere Application Server you may
be able to resolve this problem by setting
com.ibm.ws.webcontainer.invokeFlushAfterService to false
It's evident that in Spring Boot, manual configuration is not needed. So, how should I fix this error?
I am clueless how to fix. I configured the jsp resolver in application.properties.
spring.mvc.view.prefix=/WEB-INF/view/
spring.mvc.view.suffix=.jsp
I have tomcat-embedded-jasper in the pom.xml.
