Java命令行错误（无法找到或加载主类）

Question

When attempting to run the below command:

java -classpath mycompanychecks.jar:checkstyle-5.7-all.jar \
 com.puppycrawl.tools.checkstyle.Main \
 -c config.xml -r .

I get the error:

Error: Could not find or load main class \

In the directory that I'm running the command from I do have the two jar files, and also I have checked that ' com.puppycrawl.tools.checkstyle.Main ' does in fact reside in the ' checkstyle-5.7-all.jar '. As the error seems to refer to the backslash maybe it's a syntactical error? However I'm executing the command exactly as stated on the checkstyle page .

This example you're trying is clearly not about Windows.

Check here:
http://docs.oracle.com/javase/7/docs/technotes/tools/windows/classpath.html

You need to use ; as separator to say the least.

So you need something like this (this is all one line).

java -classpath c:\\test\\mycompanychecks.jar;c:\\test\\checkstyle-5.7-all.jar com.puppycrawl.tools.checkstyle.Main -c config.xml -r .
