files aren't generated using Swagger codegen plugin

I can't generate the models / controllers / services in any way, I run this command mvn clean install but it generates the files in target/generate-sources,I have used json but also yaml, How can I make this generate it for me in src/main?

For Spring Module, When I reload all maven projects from IntelliJ, it successfully resolve all dependencies but for SpringBootLocalstack if I remove "version" tag from pom file it failed to resolve, Example:
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-core</artifactId>
</dependency>
I am getting:
Cannot resolve com.amazonaws:aws-java-sdk-core:unknown
I don't want to mention any specific version here. Now my questions are:
why sometimes maven can resolve dependencies like the above "Spring" Module and sometimes can't?(SpringBootLocalstack module where I didn't mention version no)
How can we achieve compatibility safety for our maven dependencies? Is there any plugin (already tried dependency analyzer and version maven plugin but no luck)
How can we upgrade our old project to new maven dependencies without breaking the existing project feature?
Thanks in advance.

You have declared 'org.springframework.boot' as the parent module of both modules. So if some jars and artifacts like 'com.amazonaws' do not exist in 'org.springframework.boot', they won't be resolved in your project. These dependencies are not announced in 'Spring' module in your project and whatever you have declared in it, can be found in 'org.springframework.boot', then resolved. If you do not declare a 'version' tag in your pom, I guess the version of the parent (here 2.6.1) will be considered for your module version.

I think BOM (Bill of Materials) may come into rescue. If we use BOM, we don't need to specify version numbers each time we add dependencies under same parent POM. For example:
<!-- https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk-bom -->
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-bom</artifactId>
<version>1.12.138</version>
<type>pom</type>
<scope>import</scope>
</dependency>

Maven Project classes not compiling

I have a Maven Project which uses a Repast Simphony simulation. The goal is to display the simulation in the Browser which works fine. The simulation itself has been compiled beforehand and was working as intented. Now i want to change a function in one of the classes, but Eclipse wont take the change.
My Project is set up like this:
Project
-src/main/java <- My Rest Service
-src/main/resources <- My HTML, JS, CSS, etc
-repastSource <- My Repast simulation
-target <- Where the .class files land
-lib <- external .jars
In the repastSource folder there are many packages with .java-Files. These classes dont get compiled, as when i check the .class files in target they still have the old change date. I somehow compiled them once apparently, but I am not sure how I did this. I am quite new to Maven and appreciate any help.
When i run my projects with the goal of clean verify my repastSimulation .class files get deleted from the target-folder.
This is my pom.xml:

The child POM is as follows.

I have declared Logging from slf4j in parent but no maven dependencies for the same is generated in eclipse hence I am unable to use logging in the code. Can anyone let me know what is wrong here.

Using <dependencyManagement> in a parent pom allows to set the usable dependencies by the child modules.
It is a good thing as it centralizes them and specifies one and only one version.
But to use them, child modules have to declare them in the <dependencies> tag of the <build> tag.
You could for example modify the child pom in this way :
<dependencies>
...
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
</dependency>
...
</dependencies>
If you consider that these dependencies should be added in any child modules, favor dependencies over dependencyManagement in the parent pom declaration :
<dependencies>
...
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>${slf4j.version}</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>${logback.version}</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>${logback.version}</version>
</dependency>
...
</dependencies>
Now, you don't need to declare any of these in the child modules as these dependencies will be already included.
