I'm working on Java projects with Spring Boot and Maven and I'm using Intellij and I want to know if building a a project from Intellij menu: Build -> Build Project is the same thing with building a project with Maven: mvn clean install. If not, what is the difference? Thank you
If you build/compile from intellij or eclipse it will just compile the source code whereas mvn clean install will build/compile the source and creates the jar file.

I try to build a project, which is using the Maven Wrapper. The build works fine on command line. There is also a plug-in for IntelliJ Idea. However, I haven't found any article, how to build such project with Eclipse.
Do you have an experience with project build by ./mvnw command instead of mvn in Eclipse, please?
As implied by the comment from LMC, the Java edition of Eclipse will come with the "m2e" plugin, which will automatically recognize a project with a pom.xml file as a Maven project, and it will automatically note the dependencies, download them, and compile your source code with those artifacts as dependencies.
That deals with dependencies and compilation. If your build is running unit tests with Surefire, or generating code with particular plugins, unless there is a specialized m2e connector for that plugin, Eclipse will not know to do that.
Inside Eclipse, if you need to run a Maven build, you don't need to care about "mvn" vs. "mvnw". Eclipse will have an embedded Maven installation.
I can't understand Gradle and Maven in Eclipse. I know that Gradle, Maven is a build automation system.
In Android Studio it uses Gradle and I can see the files to configure them.
But I can't find them in Eclipse? Does Eclipse use Maven or Gradle? Where can I confige it.
There are Maven and Gradle plugins in Eclipse, which usually come preinstalled. You can generate Maven or Gradle projects in your workspace.
I have a Netbeans Ant project that uses a Jar file generated from a Netbeans Maven project. I would like to "include" the Maven project directly in the Ant project to be able to proper debug both projects. The Maven project was converted from an Ant project and before the conversion this include was possible. I have control over both projects, but converting the Ant project to a Maven project is not really an option at this point. What is the best approach to make an Ant based project and a Maven based project "work" together i Netbeans?
Thanks
it should work if your ant project includes the maven local repository jar as dependency. Maven support does automatic binary->open project source conversion for local repo artifacts.
When I use Maven compile, it will automatically download the depended java packages for me. Now, to debug the project, I import the project into Eclipse, but in Eclipse, the depended package is still missing. How can I get the packages? Or, can Eclipse use packages downloaded by Maven?
You don't really need to manually add all the dependencies downloaded by maven to the classpath in Eclipse. There is a maven-2-eclipse plugin which integrates maven with Eclipse. Using that plugin you can
import/create a project as Maven project or
convert an existing project into a maven project
Your Eclipse will automatically add all the downloaded dependencies on the class path everytime.
An alternative to the m2e eclipse maven plugin suggested by rocketboy is to use the maven eclipse plugin. This works from the command line (mvn eclipse:eclipse), and generates Eclipse settings for your project by downloading dependencies and putting them onto the Eclipse build path.
I have been trying to make a simple Spring project using Eclipse and Maven but I am running into problems. The first one I am trying to resolve is the fact that my code doesn't seem to compile.
For example, if in a class I type Strrrring test = new String(); there is not error at all displayed by Eclipse. I checked the Properties of the project, under Java Compiler and everything seems to be fine.
Command Line
If you have maven installed, you can make maven project working in Eclipse via mvn command. At the root of the project run:
mvn eclipse:eclipse
If you want to view the source/doc of the artifact used in your project, you can run following command instead:
mvn eclipse:eclipse -DdownloadSources=true
Eclipse Plugin
Or if you prefer use Eclipse plugin, you can install m2eclipse plugin and re-import project
Right click the project and do run as maven clean and maven install . It will work fine .
