How to Add a Maven Dependency in Eclipse

How do I add a Maven dependency in Eclipse?

1. On the top menu bar, open Window -> Show View -> Other
2. In the Show View window, open Maven -> Maven Repositories

3. In the window that appears, right-click on Global Repositories and select Go Into
4. Right-click on "central (http://repo.maven.apache.org/maven2)" and select "Rebuild Index"

• Note that it will take very long to complete the download!!!

5. Once indexing is complete, Right-click on the project -> Maven -> Add Dependency and start typing the name of the project you want to import (such as "hibernate").

• The search results will auto-fill in the "Search Results" box below.

Missing Maven dependencies in Eclipse project

Problem solved!

I don't know what exactly solved it, but I did 4 things in Eclipse:

• Window->Preferences: Maven->Installations: Global settings -> open file and hardcoded localRepository
• Project->Clean
• right click on project: Maven->Update dependencies
• right click on project: Maven->Update project configuration

I guess it was the Update dependencies since right after first two there were no change.

How to configure Eclipse build path to use Maven dependencies?

If you right-click on your project, there should be an option under "maven" to "enable dependency management". That's it.

How to add Maven Managed Dependencies library in build path eclipse?

from the command line type:

mvn eclipse:eclipse

this will add all the dependencies you have in your pom.xml into eclipse...

however, if you haven't done any of this before you may need to do one other, one time only step.

Close eclipse, then run the following command from the shell:

mvn -Declipse.workspace=<eclipse workspace> eclipse:add-maven-repo

sample:

mvn -Declipse.workspace=/home/ft/workspaces/wksp1/ eclipse:add-maven-repo

How to add maven dependencies to Scala project

1) create a project-folder with pom.xml in it.

Example;

mkdir my-project
cd my-project
touch pom.xml

2) Then add dependencies to pom.xml

Example,

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.group-name</groupId>
    <artifactId>my-project</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>jar</packaging>

    <dependencies>

        <dependency>
            <groupId>org.scala-lang</groupId>
            <artifactId>scala-compiler</artifactId>
            <version>2.12.6</version>
        </dependency>

    <dependency>
      <groupId>org.opencypher</groupId>
      <artifactId>spark-cypher</artifactId>
      <version>0.1.5</version>
    </dependency>

    </dependencies>
</project>

3) That should be it. Then you can run mvn clean compile from root of your project, which will download dependencies for you.

Example:

mvn clean compile

You can see the downloaded dependencies in local maven repo;

$ ls -l ~/.m2/repository/org/opencypher/

4) Now you can import your project using eclipse or intellij. (You can skip step 3 as IDEs can do mvn clean compile for you as well)
