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?

maven install error : 2.6 or one of it's dependicies could not be resolved

I'm trying to deploy my maven project on the application server with apache tomcat. This is my first maven project and I don't think I will use maven again. After getting too many errors and solving it, the output of the latest error is as follows. I get this error when I run the mvn install command.

version.properties file
zipkin-version=2.2.2.RELEASE

Dependencies are resolved before plugins are executed.
So the properties you read with the properties-maven-plugin are not available in the <dependencies> section.
If you want to set a dependency version by property, this property must be set inside the POM, on the command line or in the settings.xml.

You are using an old version of the plugin (1.0-alpha-2), update it to the latest 1.0.0.
Then make sure that the file version.properties is in the folder C:\Workspace. Anyway, with the latest version of the plugin you should get a proper error message if it can't find the file.
One more suggestion: spring-cloud-starter-zipkin belongs to the org.springframework.cloud group which follows another version. The suggested way to declare that dependency is like the following:
<properties>
<java.version>1.8</java.version>
<spring-cloud.version>Hoxton.SR6</spring-cloud.version>
</properties>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

jOOQ and Spring Boot pom.xml configuration problem

I am trying to setup a jOOQ and Spring Boot project with the following configuration in my pom.xml:
when I run mvn package -Pgenerate to create the classes I get a message saying
[WARNING] The requested profile "generate" could not be activated because it does not exist.
The build finishes despite the warning but there are no classes generated in the target/generated-sources/jooq folder nor anywhere in the src folder.

-Pgenerate means activate profile generate but you don't have a profile generate.
What you probably want to do is to run the jOOQ code generation
mvn jooq-codegen:generate
This can also be bound to a Maven phase like this:
<execution>
<id>jooq-codegen</id>
<phase>generate-sources</phase>
<goals>
<goal>generate</goal>
</goals>
</execution>
So when you do maven compile it will also generate the jOOQ code.

Maven: resolve versions with flatten without expanding the dependencies

I want to resolve all the revision tags after the build, so I'm using flatten. I have a multi module project like this:
A (root)
|_B (parent = A, dependencyManagement with version = ${revision}
|_C (parent = B, dependencies declared in dependencyManagement without specifying the version)
The problem is that in the flattened pom of B the ${revision} is not resolved. Moreover, in the flattened pom of C the version is still missing, whereas I'd expect to find the version declared in the dependencyManagement in B.
This is how I configured flatten:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>flatten-maven-plugin</artifactId>
<version>1.1.0</version>
<configuration>
<updatePomFile>true</updatePomFile>
<flattenMode>resolveCiFriendliesOnly</flattenMode>
</configuration>
<executions>
<execution>
<id>flatten</id>
<phase>process-resources</phase>
<goals>
<goal>flatten</goal>
</goals>
</execution>
<execution>
<id>flatten.clean</id>
<phase>clean</phase>
<goals>
<goal>clean</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
I tried to add this section inside <configuration>:
<pomElements>
<dependencyManagement>expand</dependencyManagement>
<dependencies>expand</dependencies>
</pomElements>
This partially solves the problem, because it resolves all the version, but the pom become way too verbose, because it expands all the dependencies of the parent. So the result is that the flattened pom of C explicitly contains all the dependencies declared in B e A, and the dependencyManagement of B.
Is there a way to just solve the versions without expanding all the dependencies in the child pom?

I solved this issue adding <flattenMode>bom</flattenMode> to <configuration> section in my module containing only dependencyManagement section.
According to Maven Flatten Plugin Documentation
Option bom is Like ossrh but additionally keeps dependencyManagement
and properties. Especially it will keep the dependencyManagement as-is
without resolving parent influences and import-scoped dependencies.
This is useful if your POM represents a BOM (Bill Of Material) and you
do not want to deploy it as is (to remove parent and resolve version
variables, etc.).
You can see an example below
