Mapstruct maven dependency download not working in Spring Tool Suite

STS is showing the message "Updating Maven Project: (75%)" at the bottom right corner and never ends that for hours (literally).
It happens when I add mapstruct to pom.xml (as in the first pom.xml below).
If I remove mapstruct lines from pom.xml (as in the second pom.xml below) the maven update completes just fine.
But I need to use mapstruct.
Tried with Mapstruct 1.5.1.Final and 1.5.2.Final. Same issue on both.
With mapstruct (maven update not working)

Works fine for me from STS.
Maybe your local maven repo is damaged. Try deleting folder 1.5.2.Final from $USER/.m2/repository/org/mapstruct/mapstruct/1.5.2.Final or from wherever your repo is.

Looks like you need to add a mapstruct processor.
This should help you:

Could not find or load main class after adding dependencies to the project

I have created a java project with maven in vs code. This is the pom:

the app runs. I have reloaded the project/workspace multiple times. I have really no clue, what is here the problem.
I should write some extra explanation in order to send this question, I hope, this will be enough.

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?

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>
<dependencies>

Tree Component in Vaadin latest version doesn't work
