Maven项目从eclipse正确运行但不是命令行

Question

I have a java project with a package called main and a Main class. It runs from eclipse but it doesn't work when I try this from command line in the pom.xml directory:

mvn compile
mvn exec:java -Dexec.mainClass=main.Main

I get a ClassNotFoundException on the mvn exec:java command, even though this is the correct path.

Answer 1

is the package name for your class Main called main?

The following example will create a basic project, compile it, and execute the App class

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false
cd my-app/
mvn compile
mvn exec:java -Dexec.mainClass="com.mycompany.app.App"
