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've been playing with vaadin icw gradle. When I build the application with the -Pvaadin.productionMode and then execute the jar, in the logging I see the FrontendTools installing node.
Based on the documentation I would expect the Java app to serve all js, and there needn't be a dependency/installation needed of node at runtime.

Is there a property or flag I need setting? The examples are mostly maven based perhaps I need to do a little bit more in gradle?
I build like so:
gradle -Pvaadin.productionMode
Which runs: defaultTasks("clean", "vaadinBuildFrontend", "build")
After eliminating and checking all differences between the base gradle example and my own project:
The culprit was using the com.vaadin.exampledata.ExampleDataGenerator to setup some bogus data.
If I don't, node won't install ¯_(ツ)_/¯
Not sure if that is a bug or a feature.
I ran in a weird situation I never had before.
I've got a spring boot application running on intelliJ on ubuntu 18.
My spring boot application runs in a dev environment connected to a h2 in memory database. I have a session based login with spring security.
The weird thing is if after I stopped and restarted the application I am still logged in. And even if I completely restart IntelliJ the session is not cleared. Even the database keeps its state and is not getting dropped.
Only if I restart the whole system everything will be cleared.
Inside my application.properties there are no special properties set.
Everything's on default.
If I stop the application the following console output comes up:

Update Tomcat, Jetty and Undertow to serialize session data when the
application is stopped and load it again when the application
restarts. Persistent session are opt-in; either by setting
persistentSession on the ConfigurableEmbeddedServletContainer or by
using the property server.session.persistent=true (Persistent sessions
are enabled by default with Devtools).
In spring boot 2, the property is:
server.servlet.session.persistent=false # Whether to persist session data between restarts.
I suppose you are talking about web login via browser (or REST-client). Also I suppose you're using default web security settings.
Then your login request creates a cookie with session id which is returned to browser and is being used in next requests until you close browser.
I just started to learn Spring, so I got a boiler-plate spring-boot project from https://start.spring.io/ by setting Spring-boot version to 2.0.4, Java version to 10 and added Web as dependency.

I checked the pom and found that it has spring-boot-starter-web dependency, I know that this dependency takes care of starting tomcat server but not sure why its not working.
Edit : I downloaded the project again and ran mvn clean install command and directly ran the jar thru powershell. Still getting the same error. However, this time I noticed this console output,
[ERROR] error reading C:\Users\Rajesh Raghunathan\.m2\repository\org\apache\tomcat\embed\tomcat-embed-core\8.5.32\tomcat-embed-core-8.5.32.jar; ZipFile invalid LOC header (bad signature)
It looks like your file tomcat-embed-core-8.5.32.jar is actually corrupted.
How about trying
mvn clean install -U
to force a reload?
