Could not find or load main class jar intelij

Question

After i finished my spring-boot server i want to make it a jar so i can deploy it on a remote server. I choose to do this with maven

After .jar-with-dependecies.jar is created i upload it on server and try to run

java -jar buyme-0.0.1-SNAPSHOT-jar-with-dependencies.jar

Like everybody else i get

Error: Could not find or load main class com.buyme.BuymeApplication

I tried answers from here:

Nothing seems to work. This is my

pom.xml

<build>
    <sourceDirectory>src/main/java</sourceDirectory>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>

        </plugin>
        <plugin>

                <archive>
                    <manifest>
                        <addClasspath>true</addClasspath>
                       <mainClass>com.buyme.BuymeApplication</mainClass>
                    </manifest>
                </archive>
            </configuration>
            <executions>
                <execution>

                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Manifest

Manifest-Version: 1.0
Main-Class: com.buyme.BuymeApplication

This is the project structure

mvn commands:

mvnc clean install (sometimes i tried assembly:assembly with the other two)

This doesn't work either:

java -cp <name>.jar com.buyme.BuymeApplication

Is that a full pom.xml? How come I only see the plug-in part? — Minh Kieu, Jun 05 '17 at 13:10
As @MinhKieu mentioned, your pom.xml is lacking. Shouldn't you add your dependencies there too? — Ishnark, Jun 05 '17 at 13:10
@Ishnark - That was what he added above, line #4 and it doesn't work — Minh Kieu, Jun 05 '17 at 13:11
I have too many dependencies so it would be pointless to add them here :) i just added what is important. — ALex, Jun 05 '17 at 13:13
Open the JAR and see if your main .class is inside. Maybe you didn't create a proper fat JAR with all the dependencies inside. It works if your pom.xml is correct. — duffymo, Jun 05 '17 at 13:16
It is inside: BOOT-INF/classes/com/buyme/BuymeApplication.class — ALex, Jun 05 '17 at 13:17

I managed to solve it :

I used this answer:

<build>
<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>1.5.2.RELEASE</version>
        <executions>
            <execution>
                <goals>
                    <goal>repackage</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
</plugins>
</build>
