java项目在eclipse中运行，但不在命令行中：未找到文件异常

Question

当我在eclipse中运行代码时，它运行得非常好，但是当我通过命令行运行它时，它出现了一个错误，我环顾四周，但找不到一个有效的答案。我得到的错误如下：

C:\Users\Name\Documents\Java Projects\PokemonBattle\Builds>java -jar v1.0.jar

File structure of JAR

提前谢谢

Answer 1

我假设您是从Builds目录启动程序，而不是从项目根目录启动程序。因此路径为src\data\pokemon。无法解析csv。必须将jar复制到项目根目录，或者使用java-jar Builds\v1从项目根目录启动程序。0.jar
