Spring Boot native:compile with multi module Maven build

I try to compile GraalVM Native Image for a Spring Boot 3.0 application with multiple Maven modules.
The module structure is like the following:
heroes-parent
|- heroes-backend
|- heroes-frontend
|- heroes-webapp
where each sub-directory is a module of the parent
pom.xml extract:
<modules>
<module>heroes-backend</module>
<module>heroes-frontend</module>
<module>heroes-webapp</module>
</modules>
When I try to build the app with (see Spring Boot docs):
mvn -Pnative native:compile
it errors with (because the parent has no classes):
[ERROR] Failed to execute goal org.graalvm.buildtools:native-maven-plugin:0.9.18:compile (default-cli) on project heroes-parent: Image classpath is empty. Check if your classpath configuration is correct. -> [Help 1]
So, I have tried to build the whole application first with mvn install and then only build the application heroes-webapp with native:compile
mvn install
cd heroes-webapp
mvn -Pnative native:compile
But this fails with the following error:

You can find the source code for the whole application on GitHub.
Is there any way to build a native-image with a Maven multi-module Spring Boot 3 application?

I found the issue. Visual Studio Code was open and the project was loaded using Extension Pack for Java. This was deleting the classes while Maven was building them which resulted in the error above.

Why is my java build failing using Maven?

I'm getting this error when trying to compile a java project.
[INFO] Failed to parse a schema.

[ERROR]
I'm not too sure what's going wrong here, or how to fix it in order to make it successfully build.

The error messages are from the "xjc" task of "jaxb2-maven-plugin". It is trying to generate Java source code from XSD files in the "src\main\xsd\demo" directory.
Apparently, there is a syntax problem in one or more of the XSD files.
To get more information about those syntax problems, try running Maven in debug mode; e.g. include the -X option on the mvn command line.

Angular7 + maven with IBM websphere error (frontend-maven-plugin:1.0:npm (npm install fail))

I have a complete angular7 project and want to integrate with java.
is there any way to do it?
I am using eclipse maven + ibm websphere. (not spring boot)
I referred this post(by #TimeTraveler) and tried to follow...
however when I run command mvn clean package, I encounter this error

and I also have a question .. based on that post, maven project looks like below
Maven Project -
src
main
java
resources
webapp
WEB-INF
web.xml
angular-project (I paste my angular project here)
node_installation ========>what is this?????
pom.xml
what is node_installation? .. is that a folder? do i need to create?
this is my package..

The error you posted indicates that Maven can't find the node.js executable node.exe in order to build your Angular project. Make sure you configure your pom as indicated on the frontend-maven-plugin readme page so that it will install node and npm into your project dir where maven expects to find it. This will create the node_installation directory you are missing and populate it with the node.exe executable, which should resolve the error.

Spring MVC tutorial project does not build on IntelliJ

I am trying to build and run a Spring MVC beginner lesson project using IntelliJ. I imported the existing project from GitHub. But when I try to build the project I keep getting:
Error:(3, 38) java: package org.springframework.stereotype does not exist
Error:(4, 47) java: package org.springframework.web.bind.annotation does not exist
These external dependencies jars are under my Maven local repositories (C:\Users\sudi.m2)and I can see in IntelliJ under Maven->Repositories that repo location is indeed there. I also tried "Invalidate Cache and restart" but that does not help. My M2_HOME is set correctly to C:\apache-maven-3.2.2. If I try to run mvn install from command line, I get:

Any suggestions are appreciated.

If the project doesn't have a web.xml file (IE: Entirely java config based). The build war plugin will fail unless you specify the "failOnMissingWebXml" attribute to false.

Delete you local .m2 repository and let it re-download all needed jars. Maybe, there were issues while downloading one of the dependencies.
