Deps-jar - Java

Deps-jar is a Java tool that helps you package and manage your application's dependencies into a single jar file. It's a command-line tool that you can use to create a jar file for your Java application and include all the dependencies that your application needs.

Features

Deps-jar comes with the following features:

• Easy to use command-line interface
• Can include all dependencies in a single jar file
• Supports exclusion of unwanted dependencies
• Can generate a classpath file
• Can be used with any build system

Installation

You can download the latest version of Deps-jar from the official website.

Usage

To use Deps-jar, you need to provide the following arguments:

deps-jar -d <destination> -cp <classpath> <jar-name>

• -d: Specifies the destination directory for the generated jar file.
• -cp: Specifies the classpath of the project.
• <jar-name>: Specifies the name of the generated jar file.

For example, if you want to create a jar file for a project named MyProject, you can use the following command:

deps-jar -d target/ -cp "lib/*" MyProject.jar

This command will create a jar file named "MyProject.jar" in the "target" directory and include all the jar files in the "lib" directory.

Exclusions

Deps-jar also supports the exclusion of unwanted dependencies. You can specify the dependencies that you want to exclude using the -do option:

deps-jar -d target/ -cp "lib/*" -do "log4j*,commons-logging*" MyProject.jar

In this example, Deps-jar will exclude all dependencies that start with "log4j" or "commons-logging".

Classpath generation

Deps-jar can also generate a classpath file that can be used for runtime classpath configuration. You can generate a classpath file using the -cpfile option:

deps-jar -d target/ -cp "lib/*" -cpfile target/classpath.txt MyProject.jar

This command will generate a classpath file named "classpath.txt" in the "target" directory.

Conclusion

Deps-jar is a great tool for packaging and managing your Java application's dependencies. It's easy to use, supports exclusion of unwanted dependencies, and can generate a classpath file. Give it a try and see how it can simplify your Java application development process.
