使用classpath选项运行jar

Question

我有一个项目，在两个不同的类中有两个主要方法我想使用cmd中的cp选项运行该项目的jar文件，并给出运行其main的方法。例如java -cp myjar-1.0-SNAPSHOT.jar com.xyz.DataLoader项目本身就是maven项目，在这里它是pom：

<?xml version="1.0" encoding="UTF-8"?>
<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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.xyz</groupId>
    <artifactId>myjar</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencyManagement>
        <dependencies>
            <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core -->
            <dependency>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-core</artifactId>
                <version>5.2.15.Final</version>
            </dependency>

            <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>5.1.6</version>
            </dependency>


        </dependencies>
    </dependencyManagement>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>


</project>

当我尝试命令java -cp myjar-1.0-SNAPSHOT.jar com.xyz.DataLoader时，我收到错误Could not find or load main class com.xyz.DataLoader 任何人都可以帮忙吗？

            // Print the content on the console
            logElementList.add(convertLineToLogElement(strLine));
        }
    }

    private static BufferedReader getBufferedReaderAndOpenFile(String fileName) throws FileNotFoundException {
        FileInputStream fstream = new FileInputStream(fileName);
        return new BufferedReader(new InputStreamReader(fstream));
    }

    private static LogElement convertLineToLogElement(String strLine) throws ParseException {

        return element;
    }
