ClassNotFoundException when 运行 mvn exec:java on Windows

Question

我正尝试使用 Maven 通过命令行运行我的程序。开始一切的 class 的位置是 projectFolder -> src -> frogger -> game -> MainMenu.java

我已尝试运行ning mvn evec:java，但出现以下错误：

[WARNING]
java.lang.ClassNotFoundException: frogger.game.MainMenu

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.4.0:java (default-cli) on project mainProject: An exception occured while executing the Java class. frogger.game.MainMenu -> [Help 1]

我已经尝试运行ning mvn clean install 然后 mvn exec:java 按照此线程中的建议：Class Not Found exception with exec-maven-plugin when run on Linux 但问题仍然存在。

我也试过运行ning mvn exec:java -D"exec.mainClass"="frogger.game.MainMenu"，我在其他地方找到了它，但它给我带来了与上述相同的问题。

编辑：设法通过重新排列我的文件夹结构来匹配 src/main/java

来修复它

Answer 1

按如下操作：

mvn -X clean install exec:java -Dexec.mainClass="frogger.game.MainMenu"
