This file provides brief instructions on how to add this repository to a Maven build, from Eclipse, NetBeans, IntelliJ, or the command line. Specifically, it provides instructions on creating a version of algs4.jar that you can use as a dependency in your projects.

These instructions assume that you already have installed Java 7 (JDK 1.7) or above.

Using Maven in Eclipse for Java Developers

If m2e (Maven plugin) is not built into Eclipse, follow these steps to install the plugin:

  • Open Eclipse.
  • Go to Help -> Eclipse Marketplace.
  • Search for Maven.
  • Click "Install" button at "Maven Integration for Eclipse" or "m2e" section.
  • Follow the instruction step by step.,

Restart Eclipse after installing m2e.

Now you can import algs4 as "Maven Project" into Eclipse:

  • Open menu: File-> Import-> Maven-> Existing Maven Projects...
  • Choose directory of algs4.
  • Confirm import.

To complete dependencies resolution after import:

  • Right click on the project, choose Maven -> Update Project...
  • Confirm project update.

To build project in Eclipse: Eclipse automatically builds the project every time it saved. But if you want enforce build, do following:

  • Right click on the project in Eclipse.
  • Choose Run as... Maven build.

Maven will put algs4-.jar in the directory /target. You can use this jar as a dependency in your projects.

Using Maven in IntelliJ IDEA

Import algs4 as "Maven Project" into IntelliJ IDEA:

  1. Open menu: File -> New -> Module from Existing Sources...
  2. Choose directory of algs4.
  3. Choose Import module from external model - Maven.
  4. Finish.

Last, edit pom.xml to add dependency:

<dependency>
    <groupId>edu.princeton.cs</groupId>
    <artifactId>algs4</artifactId>
    <version>1.0.0.0</version>
</dependency>

Using Maven in Netbeans

Using Maven from the Windows Command Prompt

Download and install Maven by following the instructions at https://maven.apache.org.

Locate the installation directory for Maven, e.g., C:<apache-maven-x-y-z>

Locate the installation directory for Java, e.g., C:\Program Files\Java<JDK-x-y-z>

Set the following environment variables:

set JAVA_HOME=C:\Program Files\Java<JDK-x-y-z> set PATH=%JAVA_HOME%\bin;%PATH% set M2_HOME=C:<apache-maven-x-y-z> set PATH=%M2_HOME%\bin;%PATH%

To create the algs4-.jar package and install it in the local repository for reuse from other projects, change to the directory of the algs4 repository and run Maven.

cd mvn clean install

Maven will put algs4-.jar in the directory /target. You can use this jar as a dependency in your projects.

Using Maven from the Linux / Mac OS X bash shell

Download and install Maven, either by using your favorite package manager (such as apt-get) or by following the instructions at https://maven.apache.org.

Locate the installation directory for Maven, e.g., /my/maven/

Locate the installation directory for Java, e.g., /my/java/

Set the following environment variables:

export JAVA_HOME=/my/java/ export PATH=$JAVA_HOME/bin:$PATH export M2_HOME=/my/maven/ export PATH=$M2_HOME/bin:$PATH

To create the algs4-.jar package and install it in the local repository for reuse from other projects, change to the directory of the algs4 repository and run Maven.

cd mvn clean install

Maven will put algs4-.jar in the directory /target. You can use this jar as a dependency in your projects.
