如何在批处理文件中传递java -jar参数？

Question

How can I pass java -jar arguments in a batch file ? Code below doesn't work:

set classpath = c:/users/abc/desktop/project/trunk/.CLASSPATH

java -jar java_file.jar "%classpath%"

( the java jar file needs to take the location of the .CLASSPATH file as the argument ) . In my main batch file, classpath variable takes the value depending on which project is checked out from the SVN .

Hope my question is clear.

Answer 1

That's because your set command has spaces around the = . Remove them and it works.

What you have there now essentially means that an environment variable classpath<SPACE> is set to the given value which starts with a space. Therefore, the environment variable %classpath% (without the space in the variable name) doesn't exist at all.
