How to add spring framork to eclipse in ubuntu - java

Hello I am new to Spring and Ubuntu.
I have set up eclipse kepler in ubuntu and I want to add Spring framework to eclipse but I did't understand the spring documentation and I cannot find the download link of framework. How can I add spring to eclipse.
As far as I know I have to download Spring Jar files and copy them to the classpath. However I couldn't download Spring

Download Spring Tool Suit IDE. Run some template project. These projects are maven based. This is the first step to learn and run Springframework for any OS (Windows, Ubuntu).

You have to add Spring dependencies in your build path.
Check out this tutorial.
As per my experience with Spring, it depends upon multiple jars which is tedious to manage as described above. So, personally I use Maven as build dependency management tool. You can find lots of POM.xml example in Web for Spring, however this pom.xml is from one of my project in which I've used Spring.
Maven can be used for many aspects of build process as per your knowledge and if you're new to Maven, some basic guides and tutorials will do to use Maven as build-dependency-management tool.
It would be better if you use Spring-Tool-Suite with your eclipse for productivity.
Spring's new site Spring.io is very helpful resource to learn Spring.
And Maven Plugin for Eclipse: m2eclipse

Spring Boot project searching plain jar

I am upgrading current system to spring boot 2.5.2 . I have custom spring boot starter which I installed to my local maven repository. But its generating plain jar. I installed plain jar but the project I am gonna use this starter looking for normal jar. When I disable plain jar and install normal jar , its looking plain jar. Is there any way to install both or is there any other way to look only plain jar or normal jar.
Java version is 11, Gradle version is 6.8.3, spring boot version is 2.5.2 , spring boot dependency management version is 1.0.8
In the custom starter one of the module added as a "api project" when I change that to "compile project" in build.gradle it worked. Because of "api project" when it generating jar and pom file it was adding classifier as a "plain" and it was searching plain-jar. After change it, everything worked for me.
sorry , I can't comment. I can't understand your mean.
depend on your message , I know you have write a starter that install to local maven, maybe like mvn install , but I don't know what is plain jar, what is normal jar.

To add External Spring jars for a spring project without Maven

I just downloaded the Spring IDE and Tool suite from Eclipse Market place.I am creating a sample Spring project using Spring core containers. I am following a tutorial video for that. I want to set build path by adding external downloaded Spring jars for that I have gone to build path of a specific project and I don't know where my downloaded external spring jars. I have searched in my local drive in java folder in programming files and also where my eclipse is saved. But I cannot find where my external spring jar files saved.
Kindly tell me the path where I can find external downloaded jars from eclipse Marketplace
Spring Suite tool is Rapid Application Development plugin, which helps to decrease spring configuration time and help you focus on core logic of your application.
Even though, As Martin Lippert Explain below, you might have to use Maven (Build Automation tool, And project dependency manager) for creating spring project.
people often use Maven for their dependency management (or Ivy or something else) and would like to use a specific version of the Spring framework (instead of the libs that are inside STS and used by STS itself). But you can define a user-defined Library that contains all the necessary Spring framework JARs and maybe others and just add that user-defined library to each project. Would make it a bit easier as adding several JARs all over again.
Maven uses a filesystem tree as a repository to store jar files with there metadata(dependency, version, etc.) which is located (by default) under your home or My Document Path within .m2 directory (folder).

How to program portlets efficiently using Liferay and Maven?

I can easily create a Maven project for programming portlets (for example using archetype). But in order to deploy this project to Liferay, I have to run:
mvn package liferay:deploy
Even if I change just a simple JSP file, I have to redeploy the whole portlet application. Is there a way to speed up this development process?
I don't want to use Ant, because then I would have to deal with dependencies and other stuff. I would really like to use Maven to develop Liferay portlet applications.
I tried JRebel, but because of the packaging to WAR file it's magic doesn't work :(
To re-create this situation:
Create project from maven archetype with artifactId: liferay-portlet-archetype
Add properties to pom.xml: liferay.version, liferay.auto.deploy.dir
Start Liferay
mvn package liferay:deploy -> this will create a WAR file and deploy it to liferay auto deploy directory.
Each time you want to change something, you must do mvn package liferay:deploy
This is time consuming on something bigger than just hello world.
As far as I know this is supposed to be the best practice. But Liferay documentation is sparse on this subject. Is there another way?
Problem solved using combination of STS (SpringSource Tool Suite) and Liferay IDE. With this combination it's not necessary to use Liferay Maven plugin at all. Just simply add Liferay server, deploy Maven app on this server and it all works.
Using this combination with JRebel is IMHO the most effective solution.
Your application can be packaged in WAR for JRebel to work, no problem there. Did you put rebel.xml configuration file into the WAR?

Best way to work with Java projects using Maven and Eclipse with embedded Tomcat?

I've run non-Maven applications on an Eclipse embedded Tomcat server before and I found the instantaneous deployment upon saving invaluable. However after starting a Maven project I didn't find any easy way to continue doing this.
Using WTP and the Dynamic Web Module Project Facet seems to wreck the project's Maven nature. Using JRebel is not possible in our company. Googling didn't provide any results that would work without again removing the project's Maven support. Is there any other way or am I doing it wrong?
Install m2elipse with WTP extension. Import your Maven WAR project. m2eclipse will configure Eclipse for and your can continue using your Tomcat in WTP.

spring framework: How can i start a web project with eclipse j2ee indigo?

I'm on debian-6.
I have install ant,tomcat6,openjdk-6-jre.
Now from eclipse which project would i create as spring framework ?
I'm also following this => http://static.springsource.org/docs/Spring-MVC-step-by-step/part1.html
But i can't understand how to start with eclipse for spring framework MVC .
Did i miss anything ?
Open your Eclipse go to Help>Eclipse Marketplace and search Spring IDE. Install it and at the end (afer installation and eclipse restart) you should have a spring project menu on File>New tab. But i suggest you to use maven instead of ant to build you apps.
Download Spring Source Tool Suite (STS) -- it is an free Eclise provided by Spring Source containing the plugins you need (spring ide, m2eclipse, aspectJ, ...). So you do not need to download them all by hand.
It is fully compatible with the normal Eclipse so you can install all other plugins you want to have.
Btw as far as I know, the Spring IDE contains not all the features that STS provides.
STS contains in the new project wizard the category: "SpringSource Tool Suite" (not "Spring"). Within this category is the Project template "Spring Template Projet". After selecting this you can choose what you need. For example "Spring MVC Project".
