Custom library to Maven local repository

PS: Some jars do not support Maven

 

For example, kaptcha, a popular third-party Java library that is used to generate "captcha" images, is not in Maven's central repository.

Here's how to install the "kaptcha" jar into Maven's local repository.

1. mvn install

Download "kaptcha", unzip it and copy kaptcha-version.jar to C drive. Issue the following command:

mvn install:install-file -Dfile=c:\kaptcha-{version}.jar -DgroupId=com.google.code -DartifactId=kaptcha -Dversion={version} -Dpackaging=jar

Example:

D:\>mvn install:install-file -Dfile=c:\kaptcha-2.3.jar -DgroupId=com.google.code
-DartifactId=kaptcha -Dversion=2.3 -Dpackaging=jar

Now, the "kaptcha" jar has been copied to the Maven local repository.

2. pom.xml

After installation, declare the kaptcha package in pom.xml.

<dependency>
      <groupId>com.google.code</groupId>
      <artifactId>kaptcha</artifactId>
      <version>2.3</version>
 </dependency>
