Question

I am trying to run a Small basic Spring boot program on my machine and I when I run clean compile (even before trying spring-boot:run) on maven I get the following Error :

@SpringBootApplication
public class SpringBootPocApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootPocApplication.class, args);
    }

}

I tried many solutions I could find on internet, such as deleting the .m2 repository, adding different tags (version, fork,...) to the spring-boot-maven-plugin plugin which, I'm pretty sure, is the part causing the problem

Any suggestions ?

You need add this dependency

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

then it will work.

This worked ! as well as the answer of Darren Forsythe, I have a question though: why do I need to add that dependency ? since I am including a parent in my pom, this means that all the dependencies I need are retrieved from that parent so why I have to add another dependency in order for my project to compile ? – FrankelStein Feb 18 '18 at 16:57

If the parent declares dependencies, which are inherited, that would be correct. However, the Spring Boot parent only declares dependencyManagement, which will only manage versions and scope, but the dependencies itself are not added in child projects. – dunni Feb 18 '18 at 20:48

You have 0 compile dependencies, only test-compile dependencies defined, because you've commented out spring-boot-starter-data-jpa. Spring starter's pull other dependencies in (including other starters) to create everything needed at compile time. Un-comment the spring-boot-starter-data-jpa dependency, and/or re-evaulate what dependencies you actually want.

The parent POM is for managing dependencies, they are _all_ optional, thus you need be explicit and define them yourself. – Darren Forsythe Feb 18 '18 at 16:59

1) Close the project 2) Import the project again with auto-import checked

This worked for me. Maybe works for you too.

If any Wrapper folder is present inside .mvn folder of your project delete it. Also, Go to File->Settings->Build,Execution,Deployment->BuildTools->Maven->Set Maven home path as Bundled(Maven 3)

Add the below section outside dependency management and do an update of project. And then the clean install of maven.

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.10.RELEASE</version>
    </parent>

And the below dependency.

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

If does not fix (Not Likely to happen) then add the other dependencies mentioned here

If you don't need web related libraries, you can add this dependency instead of spring-boot-starter-web mentioned in other answers:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

sometime project got problem during compile or got problem. Step for the solution :

check if the dependency is valid. On the topic, dependency is valid. Check the name on dependency to make sure, include the Hirarky.
check your java. I tried using version 19 and it work fine then using 17 is fail!! but following example on youtube, the code work. Then the next step reload the project. Make sure your Java is up to date or newest.
Reload project. This can be execute from command prompt (mvn -U idea:idea) or from your ide (on Intellij, choose your project folder -> maven -> reload project). You can try other way related to reloading your IDE. My recommendation is using command prompt. If you using IDE, try reload the project before close and open project.
if nothing work.. delete .idea and then open and close your project (not recommended). When following step 3, your idea folder should be clean. Make sure your IDE not open this project before deleting the folder.
use recommended IDE (related to reff link). This is just reminder.

notice: this tested on windows.

hint: sometime using lower version JDK can help. If you follow manual, try to use same version. My fault is using 19 not 17 (on youtube). The newest version have more advance than before, if you still learning following your mentor/teacher is recommended.

summary from here:

If you have this dependency below, but still you have this error:

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
</dependency>

your maven still doesn't download it, for this issue may you need to vpn or check internet connection. I have the same error and I use vpn, next in "Intelij IDE" in maven window( right side) if you can not see that, you should active that, next click on "reload All Maven project" and it download it and then you can see your problem has fixed. may it helpfull.

I was facing this issue and nothing was working out. I tried one of the solution to change maven home path. Intelij -> Preferences -> Build, Execution, Deployment -> Build Tools -> Maven

Here I changed the Maven home path from Use Maven Wrapper to Bundled (Maven 3) and everything became fine.

Had the same problem (using IntelliJ), and to solve it went through a variety of steps (not necessarily in this order), and my issue was solved:

Make sure the pom.xml in your project directory has
```
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
```
For that one can also access the Dependencies by clicking ALT + Insert

Then search for spring-book-starter-web (or a similar variation), and click Add.
Invalidate all Caches (File > Invalidate All Caches)
Remove the .idea folder in your project directory
Uninstall every Java: JDKs and Java 8, that I had installed.

I've used Revo Uninstaller for this, but if one is in Windows, one can also go to Settings > Apps > Apps & features (as it says here).

Then restart the machine.
Install the JDK for the Project through IntelliJ.

For that, go to File > Project Structure > Platform Settings > SDKs.

More on this here.
Update IntelliJ to a newer version (assuming it's not up to date).

As I use JetBrains Toolbox, just add to access it and it was straightforward.

One can also update by
Make sure one has MAVEN_REPOSITORY pointing to the right place.

Eg. C:\Users\goncalo\.m2\repository.

Confirm that in File > Settings > Appearance & Behavior > Path Variables.
If the Project directory has a folder called target,

Go to the Maven (in my case it is on the right-top of the IDE) and, in the Lifecycle click clean

Then try to run the project again.
