使用外部jar文件夹运行JAVA项目

Question

I'm trying to execute my JAVA app on a Linux OS where the necessary jars are located in a different folder. How can I execute my project using the external jars?

project location:

$ pwd
/root/MyApp/bin
$ ls
Deletion.class

jars location:

/opt/jars/*.jar

My failed execution:

$ java Deletion
... NoClassDefFoundError ...

$ java -cp "/opt/jars/*.jar" Deletion
Error: Could not find or load main class Deletion

Answer 1

使用-cp ...设置类路径时，还必须指定当前的工作目录（因为该目录已不再存在）：

java -cp ".:/opt/jars/*.jar" Deletion

Answer 2

java -cp "location of jar file:." Deletion
