No clear what is "repository" of algs4

[powazny]

Hello,

What is the Maven dependency and what is the repository we should to use to build application using Maven?

Could you please provide the appropriate entries we can use in pom.xml in the project?

Best regards
Powazny

OK, so I think I figured this out. If I want to include algs4.jar in your own Maven project, this is what you do (assuming you have Maven installed):

1. Clone this repo.
2. Build the jar file with mvn compile
3. Copy the resulting jar file somewhere handy in your project. I created the lib directory
4. Install the jar in your project with

  mvn install:install-file -Dfile=lib/algs4-1.0.0.0.jar -DgroupId=edu.princeton.cs -DartifactId=algs4 -Dversion=1.0.0 -Dpackaging=jar

Add the following to your project's pom.xml :

<dependency>
    <groupId>edu.princeton.cs</groupId>
    <artifactId>algs4</artifactId>
    <version>1.0.0</version>
</dependency>

and that seems do it.
In theory one should be able to install the generated jar with mvn install:install-file -Dfile=<path-to-file> but this did not work for me.

As for the Maven Central Repository that didn't seem to work for me at all, and I suspect even if it did, the resulting import statement would be something like import com.google.somethingsomethign which I'd have to change before trying to submit assignments.

I think the algs4.jar from the book site didn't work maybe because of version info? But when you build your own with this repo, you can see what you're getting.

The Maven and Gradle info was created by Peter Korgan. I don’t use Maven, so can’t provide much more information. https://github.com/kevin-wayne/algs4/blob/master/README-MAVEN.txt https://github.com/kevin-wayne/algs4/blob/master/pom.xml There is also a bintray link https://bintray.com/algs4/maven/algs4 If the instructions are unclear, feel free to suggest improvements.

Currently there is a algs4 in maven central repository:

<dependency>
    <groupId>edu.princeton.cs</groupId>
    <artifactId>algs4</artifactId>
    <version>1.0.3</version>
</dependency>

From the version number and last update time it seems apparently not done by Princeton but others. The sources there is not synchronized to the latest here, so those who want to use it should keep this in mind - take risk on your own.

@Momus I don't think it needs that many steps, after clone the repository you just need to execute mvn clean install and all will be settle down.

git clone https://github.com/kevin-wayne/algs4 && mvn clean install

Then add below to your pom.xml:

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

The solution above worked for me 👌.

EDIT: Actually, I needed to cd into algs4 directory before executing mvn clean install. Future readers, keep this in mind.

@ny83427 very nice ！
