问题

我们有以下的Java命令，之前一直运行正常，突然间停止工作了：

java –cp "classes:lib/*" xxx.yyy.ppp

这个jar包在lib目录下，而且jar包中包含了这个类。
突然间它停止工作了，并显示了以下错误：

"Error: Could not find or load main class –cp"

为什么它把 '-cp' 当作了主类，即使 ppp（例如）有主类。请帮我解决这个问题...

英文:

We have the below java command which was running and stopped working all of a sudden,

java –cp "classes:lib/*" xxx.yyy.ppp

The jar is within lib directory and the jar contains the class.
It stopped working all of a sudden and gived the below error,

"Error: Could not find or load main class –cp"

Why is it considering '-cp' as the main class, even though ppp (example) has the main class. Please help me out with this...

使用此命令而非默认的连字符，在 java -cp "classes:lib/*" xxx.yyy.ppp 前加上连字符：java -cp "classes:lib/*" xxx.yyy.ppp。

英文:

You are not using a default hypen before cp as java –cp "classes:lib/*" xxx.yyy.ppp

Use this instead : java -cp "classes:lib/*" xxx.yyy.ppp
