正确设置插件后，Maven无法找到或加载主类

Question

I have a problem, when I set up my pom.xml, my application still wouldn't run, saying it could not find or load main Class. I have setup my pom.xml as stated here

My pom.xml:

<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">

                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

    <dependencies>
        <!-- https://mvnrepository.com/artifact/commons-configuration/commons-configuration -->
        <dependency>
            <groupId>commons-configuration</groupId>
            <artifactId>commons-configuration</artifactId>
            <version>1.6</version>
        </dependency>
    </dependencies>

</project>

I use command mvn clean compile assembly:single to package the application and then run it with java -jar outputedJar.jar

This is what MANIFEST.MF which is inside that jar, says:

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: xxxx
Build-Jdk: 1.8.0_121
Main-Class: com.example.EditPropertiesFile.Main

However, when I run, i get next error:

Error: Could not find or load main class com.example.EditPropertiesFile.Main

I don't know what else I can try, as I have tried various answers all over SO and they all seem to fix some other issues.

EDIT: output when running command:

Inside the jar file there is no file Main.java

Structure of my project:

Answer 1

Check/Extract jar file and look for the Main class is added in the jar file or not, Also, check the package structure.

Also, can you add the Output logs coming from mvn during the execution of mvn command you mentioned.

[ update ] Looks like your directory structure may be an issue, so check if thats correct or not. For instance in this case if baseProjectDir is your directory where you have pom.xml (baseProjectDir\\pom.xml) then your Main.java should be residing in below directory relative to baseProjectdir: baseProjectDir\\src\\main\\java\\com\\example\\EditPropertiesFile\\Main.java

Answer 2

If the main class is EditPropertiesFile remove .Main

also,add to pom.xml :

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.0.0</version>
<executions>
    <execution>
        <phase>package</phase>
        <goals>
            <goal>shade</goal>
        </goals>
        <configuration>
            <transformers>
                <transformer
                    implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                    <mainClass>com.example.EditPropertiesFile.Main</mainClass>
                </transformer>
            </transformers>
        </configuration>
    </execution>
</executions>
