how to add multiple jar(s) to classpath?

Question

我有超过25个jar文件如何在类路径中添加所有这些文件？

Answer 1

If all the jar files are in the same folder, as of jdk6, Java supports classpath wildcards. http://download.oracle.com/javase/6/docs/technotes/tools/windows/classpath.html

So you can use something like,

/path/to/jar/*

Also consider having a separate classpath for each project.

Answer 2

Separate them with a colon / semicolon ( : / ; ) on *nix / win

But it would be way easier to use an IDE (Eclipse, NetBeans) to handle the classpath for you.

Answer 3

此外，如果类路径太大而无法将其放在命令行上，则可以设置CLASSPATH环境变量（应将其设置为以分号分隔的JAR列表）。

Answer 4

Consider using Maven to manage your dependencies. It'll go a long way to prevent JAR-hell.

Answer 5

I use eclipse, so there is a for me to first put them into a folder. After which if I need to add it to build path, I just go to the build path option to browse to the folder and select all. You can also import them easily by browsing to the folder and select all too.
