Maven Eclipse Integration Issue

Question

I am having an issue with Maven integration. I have recently downloaded Eclipse Luna (with JDK 8 patch) and using it on Ubuntu OS.

I have created a Maven project with simple artifact and now when I add write some dependency in my pom.xml file and then test it, the Maven build is successful, but in my Java build path, the JRE System Libraries [J2SE-1.5 ] is present but my Maven Dependencies does not contain anything in spite of writing a few dependencies in my POM.xml file.

This is my pom.xml file

<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.test</groupId>
    <artifactId>testproject</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <dependencyManagement>

        <dependencies>
            <dependency>
                <groupId>org.apache.lucene</groupId>
                <artifactId>lucene-core</artifactId>
                <version>5.0.0</version>
            </dependency>

            <dependency>
                <groupId>org.apache.poi</groupId>
                <artifactId>poi</artifactId>
                <version>3.10-FINAL</version>
            </dependency>

        </dependencies>

    </dependencyManagement>


</project>

Due to my Maven dependencies being not present in my build path, hence, I am not able to use the libraries which are to be added by Maven.

you have to put the dependencies outside of <dependencyManagement>

    <dependencies>
        <dependency>
            <groupId>org.apache.lucene</groupId>
            <artifactId>lucene-core</artifactId>
            <version>5.0.0</version>
        </dependency>

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>3.10-FINAL</version>
        </dependency>

    </dependencies>

see the documentation for what <dependencyManagement> should be used:

The dependency management section is a mechanism for centralizing dependency information. When you have a set of projects that inherits a common parent it's possible to put all information about the dependency in the common POM and have simpler references to the artifacts in the child POMs.
