I am new to Spring and learning spring boot and I have used maven for dependency manager and have built a crud application and now I am looking to explore it more. I am wondering if spring has open source package website which list them like how we have https://packagist.org for php packages.
I am using mvnrepository. It has dependencies for maven, gradle, ivy and some others.

For years, I've used Spring Initializr (at https://start.spring.io/) to create the initial SpringBoot application and then modify it to create the app. This works fine.
Is there a maven archetype I can use to create a SpringBoot app? Or is the Spring Initializr the only way to do this.
Searching I found this:
What archetype to choose for a simple java project
Which shows the command:
mvn archetype:generate -Dfilter=org.apache.maven.archetypes:
Which gives me a list of 14 items to choose from. None of them mention SpringBoot.
The closest match is org.apache.maven.archetypes:maven-archetype-webapp, so I tried it and it created a WebApp (*.war) which is not what I'm looking for.
The aim of the Maven archetype is for generating a project skeleton. The Spring Initialiser also does the same but I think you should find it more user friendly to use when compared to executing a maven archetype command.
If you insist to use maven archetype , you can simply search Github to see if there are people share their archetypes (search result at here)
If your aim is just to use command to generate a spring-boot project skeleton , Spring Initializr actually provide an HTTP API to do it.
Also you can checkout JHipster, which is another tool to generate a spring-boot project skeleton.
You could also use Spring Boot CLI to scaffold new Spring Boot projects:
spring init --dependencies=web,data-jpa my-new-project
It works just as Spring Initializr, but on the command line.
See section 2.4 "Initialize a New Project" on Spring Boot CLI documentation here: https://docs.spring.io/spring-boot/docs/current/reference/html/cli.html#cli.using-the-cli.initialize-new-project
I am new to spring. I am not able to figure out how to write a spring project for creating DB connection using maven , without using spring -boot or hibernate. it is supposed to be a simple spring maven project.
can you help me with few sample codes.
Install the Spring tools suite plugin for eclipse from the following link.
With spring tools suite, access the spring dashboard
Select the Import Reference App, this will provide several example applications from the Spring guides, choose the example and the example will be installed onto your eclipse workspace. These examples are well documented , with clear instructions on how to run the project. Hopefully this should help you get started with learning Spring framework.
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
Is Spring tightly coupled with Maven ? Most of the examples in the internet shows Spring and Maven to configure spring dependent jars, this post explains so many cons of Maven. All commercial projects are should to be using only this combination ?
Please explain
Thanks
Both of them serve different purposes, Spring examples use Maven because maven is highly adopted as a build, dependency management framework. That has nothing to do with Spring coupling with Maven. Spring is a framework to build enterprise applications and Maven is a build and deploy tool.
You can use Gradle, ivy or even manually download the libraries instead of relying on Maven as the dependency management framework.
No. You can use whatever you want to build your Spring-based app. BTW, all the Spring tutorials show examples using Gradle (that Spring also uses internally).
What is true, though, is that Spring jars are available from the Maven central repository and the Spring repository, and that their dependencies is thus described in a Maven pom.xml file. But nothing prevents you from downloading the required jars manually and add them in the classpath.
I'm new to Spring framework and for the first program. I'm trying to download Spring jars and many websites gave "http://projects.spring.io/spring-framework/" link and there is no download provision there.
Trying to download Spring jars for past one hour.
Can someone provide me a link where I can download Spring jars.
spring-source.jar
common-loggings.jar
best option its add spring to maven dependency and then You dont need woory about, from where take spring jars
