错误：无法在 Java Maven 项目中找到或加载主类

Question

I am working in Java Maven project. There is a .bat file in the root of the project which invokes a Java class with some arguments something like this:

java my.package.MyClass abc hi 1

Now, my project jar is built in the target directory of that project when I do mvn clean install . When I run that .bat file it gives me the below error

Error: Could not find or load main class my.package.MyClass

Project's pom.xml only contains jars as dependency.

Do I need to do something in pom.xml to make it work?

Answer 1

please provide your pom.xml so we can look for it, anyway,

do you use maven-jar-plugin ?

something like this

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-jar-plugin</artifactId>
   <version>2.4</version>
   <configuration>
     <archive>
       <manifest>
         <addClasspath>true</addClasspath>
         <classpathPrefix>lib/</classpathPrefix>
         <mainClass>your.main.class.package.ClassName</mainClass> // your main class
       </manifest>
     </archive>
   </configuration>
 </plugin>

and try to run your *.jar with command java -jar yourjar.jar
