I am new to spring boot and for build tool i am using Maven .
I wanted to know that how does spring boot application runs after maven build process finishes like
What is the output of the build ?
How build is executed ?
Although much of the detail about the build and run process is abstracted away by IDE (like IntelliJ) but i am curious to know about what happens internally ?
The spring-boot-maven-plugin Maven Plugin can generate an executable JAR which includes all dependency JARs and start-up, classloader code in addition to you application code.

I have a struts2 project that I launch with a jetty server. I would like to make a dockerfile allowing me to create a struts2 image (to be able to launch it with a compose docker), my problem is that I have the impression that there is no documentation about struts2 to create the dockerfile, would you have some tricks to propose to me? Thank you in advance for your answer
Struts is part of the application scope and shouldn't be packed in a docker container by itself. It's should be packed in the EAR or Spring Boot application (for example) you are working on. You have to deploy/add the EAR or Spring Boot application to the docker image.

I'm trying to get a maven plugin (specifically Jacoco) to run on every maven project, but I can't find much info on this. I don't think settings.xml would work and the lifecycle extension documentation isn't very helpful either.
Any ideas?
Usually, you declare such plugins in a company parent POM and use it as parent in all your projects.
according to maven doc
https://maven.apache.org/settings.html
I think that you can't enforce a plugin on every maven project of a given host. there's no settings directive to do that.
Anyway you can facilitate the command line plugin dedicated goal through pluginGroups settings section.

I am new to Jenkins, I configured Jenkins with my CVS and I am stuck, after building the project using Jenkins I need it to be deployed automatically into the server so I can access the project.
This can be achieved by adding a "post-build" action in Jenkins, action of type can be "Deploy war/ear to a container" - that let's you define your configuration. Your question is too broad. I would suggest you read up on jenkin configurations or at least tinker with it.

I'm creating a servlet-based application using Tomcat.
Besides that i've some classes to acces a DB with jdbc. (present in a other folder/package)
I was asking myself how to integrate them cleanly in my servlet-based application.
What's the "cleanest" solution ?
thx
I would go with packaging as a separate JAR file and placing in WEB-INF/lib of your web app.
While it may seem easier to just put JAR to the common libraries folder so that several web apps start using it - it will result in not being able to upgrade the JAR without restarting the whole server. Also you will need to make sure that the new JAR is working fine with all of the apps. Classpath issues are possible with this approach too.
Package them in jar files and then add files to you're project.
