Can I Use Wildcards in My Classpath to Include Multiple JARs?

Using Wildcards in Classpath to Include Multiple JARs

Many Java developers use numerous third-party libraries, leading to a cluttered CLASSPATH with numerous JAR file paths. To streamline this process, it's worth exploring if wildcards can be employed to include all JAR files within a folder.

Can Wildcards Be Used?

According to Oracle's documentation, the basename wildcard character "" is indeed supported in classpath entries. By specifying foo/, all JAR files within the "foo" directory will be included. Similarly, * alone expands to all JAR files in the current directory.

How to Use Wildcards

To use wildcards in the classpath, simply include the following entry:

foo/*

This will include all JAR files within the "foo" directory. In Java 6, this should work correctly. However, if it doesn't, try enclosing the path in quotes:

"foo/*"

Advantages of Using Wildcards

Wildcards simplify the classpath by significantly reducing the number of JAR file paths required. It becomes easier to manage and maintain, improving code readability and reducing errors from missing or duplicate entries.
