when I run mvn clean install the .jar is generated but when I launch it java -jar target/test-1.0.0-BUILD-SNAPSHOT.jar
I have an error

I don't understand, I have no errors in eclipse, I think the .jar is in maven depences
If you would like to stay in spring boot space just set the pom packaging to jar
<packaging>jar</packaging>
and add the spring-boot-maven-plugin to you build properties in the pom.xml file:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
then a simple mvn package command will create a complete executable jar file.
See the very good spring reference doc for more details (doing it gradle style also)

Mine was caused by a corrupt Maven repository.
I deleted everything under C:\Users\<me>\.m2\repository.
Then did an Eclipse Maven Update, and it worked first time.
So it was simply spring-boot.jar got corrupted.
The answer to the above question is "none of the above". When you download new STS it won't support the old Spring Boot parent version. Just update parent version with latest comes with STS it will work.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.8.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
If you have problem getting the latest, just create a new Spring Starter Project.
Go to File->New->Spring Start Project and create a demo project you will get the latest parent version, change your version with that all will work. I do this every time I change STS.
Here the packaging is jar type, hence you need to use manifest plugin, in order to add dependencies into the Manifest.mf
The problem here is that maven could find the dependencies in pom file and compile the source code and create the output jar. But when executing the jar, manifest.mf file contains no details of dependencies. Hence you got this error. This is a case of classpath errors.
Here you can find the details on how to do it.
Another option is to use the Apache Maven Shade Plugin:
This plugin provides the capability to package the artifact in an uber-jar, including its dependencies and to shade - i.e. rename - the packages of some of the dependencies.
add this to your build plugins section
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
</plugin>
May be your dependencies not build correctly. Check compilation issue in project.
Clean and rebuild project.
For maven project:
mvn clean install
For gradle projects:
gradle clean build or gradlew clean build
Adding below to pom.xml solved my problem
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
I had the same problem and tried most of the solutions suggested above, but none worked for me. Eventually, I rebuild my entire com.springframework (maven) repository (by simply deleting .m2/org/springworkframework directory).
It worked for me.
You need to also copy the required dependencies next to your resulting jar and include them in the classpath. An alternative is to use maven-shade-plugin.
Snippet for the first option:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.3.0</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<overWriteReleases>false</overWriteReleases>
<includeScope>runtime</includeScope>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.2.2</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>your.class</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
In my case, I followed these steps
Clean your .m2 folder in your c:/users/your-host-name/.m2
Ensure your pom.xml has this for the buile
org.springframework.boot
spring-boot-maven-plugin
3.0.1
Update your maven, in IntelliJ, this is done by clicking

Finally, build your jar by using the Maven package button
