In Eclipse (STS) I created a project as follows:
File -> New -> Spring Starter Project
The settings are (among others):
Type: Maven Project
Packaging: War
Java Version: 1.8
Language: Java
Boot Version: 1.3.0
Dependencies: Web
In the project facets it leads to Dynamic Web Module = 3.1, however I need 3.0.
Manually setting it to 3.0 leads to "Cannot change version of project facet Dynamic Web Module to 3.0".
Besides this error message I am sure this is not the right way to change it because the project will be shared to others.
I guess there is a maven way.
Maybe the solution is somewhere here: http://docs.spring.io/spring-boot/docs/1.3.0.RELEASE/maven-plugin/plugin-info.html.
Unfortunately Spring Boot and Maven are not my special topics (yet).
Not the correct way but, the easiest way to fix that issue is 'Delete' that error from the 'Problems' tab. It will be removed and your code will be compiled on STS. But, it may come back at some point then just delete that error again.

I'm trying to deploy my spring boot project (made by spring initializr) with maven (but same issue with gradle) on WebSphere Application Server 8.5.5 but it seems impossible to me.
Every-time I try to add to server from "Add and Remove" it says "There are no resources that can be added or removed from the server".
So I tried changing Dynamic Web Module on Project properties --> project facets but nothing changed.
Is it possible to deploy on WAS 8.5.5?
I found a similar reported issue here: Cannot 'Add and Remove' Maven Project with Websphere 7 on RAD 8.5.
I completely removed my project from RAD. I then extracted zip file from Spring Initializr to create a Maven project. I used "mvnw eclipse:eclipse" command and it successfully created build. I imported that as a general project to RAD.
I then clicked on project. Clicked on properties. Clicked on project facets. None were available, but it prompted me to create them and I did. From there, I selected Dynamic Web Module facet (and also JAX-RS, but I'm not sure if you'll care about that one). I clicked apply and close.
After this, I was able to add and remove resource to Websphere server. I don't know if this is preferred steps or not. I am learning, just as you are. But, it appeared to work.
I specified Java 8 Jar in Spring Initializr for packaging. Maven version is 3.8.4. Spring Boot 2.6.5 (it was pre-selected for me). I am using RAD 9.7 and Websphere server that is stood up in IDE is version 8.5.5.
To deploy spring boot to WebSphere 9 you would want to choose War packaging and Java 8. The zip file from the spring initializr includes a Help.md file with links to helpful documentation. After you extract the zip file, use File -> Import existing maven project into a new workspace.
I have an existing project. I need to make it a Spring boot based project and I am using IntelliJ CE.
What would be correct procedure for doing it?
Edit:
Project has no initial structure. It is a totally empty project. So no existing modules etc.
Spring Boot is an Ultimate feature, so first you would need to try/buy the IntelliJ IDEA Ultimate.
From there, you can add Spring support to existing project modules or use the Spring Initializr wizard to select the necessary configuration when creating a new project or module.
In your maven pom.xml or build.gradle file, I would add the spring boot starter dependency:
spring-boot-starter (the group id is org.springframework.boot)
If the application is a web application, I would also add the web starter spring-boot-starter-web also with the same group id (org.springframework.boot)
For convenient features, applying the spring boot plugin would help in creating a runnable jar with all required dependencies bundled called a fat jar.
A great tool I use is the spring boot project generator. It allows you to configure the modules you want and create a project template.
Spring Boot requires IntelliJ IDEA Ultimate. If you want to use IntelliJ CE, please create a project using Spring Initilizer then import the same to your IntelliJ CE (File -> Open -> Choose the project root folder). After you import the project, wait for some time so that IntelliJ can download the dependency and build your project. You can check from (Build -> Build your project). Then find the main class of spring boot and run it using the green play button
I´m new with Jersey and I have problems with the installation. Specially with the error:
Can't resolve Archetype
org.glassfish.jersey.archetypes:jersey-heroku-webapp:2.26
I already looked for solutions:
adding a remote catalog
adding a new Maven Archetype locally
proxy setting are working (I can access a web page using my internal browser)
Now, I noticed that when creating a new Maven project and selecting the archetype it appears:
com.sun.jersey.archetypes
Can I use that to run jersey? or Is only with
org.glassfish.jersey.archetypes
any suggestions?
com.sun.jersey.archetypes <- Jersey 1.x (see docs)
org.glassfish.jersey.archetypes <- Jersey 2.x (see docs)
For new projects, use 2.x
I searched spring on maven, and I find it at this page :http://mvnrepository.com/artifact/org.springframework/spring. The problem is I want to download 4.0 version but there is no 4.0 version in the chart.
Newer version of Spring can be found under group id org.springframework - Spring 4+
There is no reason to include all features of Spring Framework in one .jar. Spring is huge and you will probably won't use every feature of Spring. Including everything will cause unnecessary overhead. Pick what components you need add them to pom.xml and Maven will download them. If you found out later you need additional dependency just add it on the fly...
As an alternative you can use Spring Boot which will generate project for you with default set up. You can generate such a project using Spring Initializr Spring Boot Initializr. At the bottom click Switch to the full version. Pick what you need and hit generate project.
I am using Spring Boot version 1.2.4.RELEASE to generate a simple web project. The full Url for creating this project is:
http://start.spring.io/starter.zip?name=demo3&groupId=org.test&artifactId=demo3&version=0.0.1-SNAPSHOT&description=Demo+project+for+Spring+Boot&packageName=demo3&type=maven-project&packaging=jar&javaVersion=1.7&language=java&bootVersion=1.2.4.RELEASE&dependencies=web
The download starter project opened in the STS 3.6.4.RELEASE with tons of errors: Missing artifact, ArtifactDescriptorException from the pom.xml file.
However, if I use version 1.1.12.RELEASE of the Spring Boot, I have no problem to create the startup project.
Is this a bug in the 1.2.4.RELEASE of the Spring Boot? I doubt it.
The project is OK.
Please to check your local env, specially connexion, maven configuration (setting.xml), ...etc
Good luck
