如何在Eclipse中向Maven项目添加Spark？

Question

I would like to start Spark project in Eclipse using Maven. I've installed m2eclipse and I have a working HelloWorld Java application in my Maven project.

I would like to use Spark framework and I'm following directions from the official site . I've added Spark repository to my pom.xml :

<repository>
      <id>Spark repository</id>
      <url>http://www.sparkjava.com/nexus/content/repositories/spark/</url>
</repository>

And then the dependency:

<dependency>
      <groupId>spark</groupId>
      <artifactId>spark</artifactId>
      <version>0.9.9.4-SNAPSHOT</version>
</dependency>

But I'm getting an error in Eclipse:

Missing artifact spark:spark:jar:0.9.9.4-SNAPSHOT

How can I resolve this issue? I don't want to download Spark's jar file and place in the local repository.

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.myproject</groupId>
  <artifactId>Spark1</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>Spark1</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <repository>
      <id>Spark repository</id>
      <url>http://www.sparkjava.com/nexus/content/repositories/spark/</url>
  </repository>

  <dependencies>
<!--     (...) -->

    <dependency>
      <groupId>spark</groupId>
      <artifactId>spark</artifactId>
      <version>0.9.9.4-SNAPSHOT</version>
    </dependency>

  </dependencies>

</project>

Answer 1

Currently no repository is required to add for Spark library loading

You just need to add

<dependency>
    <groupId>com.sparkjava</groupId>
    <artifactId>spark-core</artifactId>
    <version>2.6.0</version>
</dependency>

And that's it.

Answer 2

The repository block needs to be wrapped in a repositories block:

<repositories>
    <repository>
        <id>Spark repository</id>
        <url>http://www.sparkjava.com/nexus/content/repositories/spark/</url>
    </repository>
</repositories>

Answer 3

Reason for failure is 0.9.9.4-SNAPSHOT is not available.Below is the list of the snapshots available. Use one among them based on your requirement.

0.9.8-SNAPSHOT/ Sat May 21 21:54:23 UTC 2011
0.9.9-SNAPSHOT/ Mon May 23 10:57:38 UTC 2011
0.9.9.1-SNAPSHOT/ Thu May 26 09:47:03 UTC 2011
0.9.9.3-SNAPSHOT/ Thu Sep 01 07:53:59 UTC 2011

Answer 4

I had run into same issue because initially I started with different repository url for spark and then to use earlier version I changed the repository url. Some how it didn't seem to come into effect until I changed the repository id. Try changing the repository id.
Could be bug in maven because running maven from console also couldn't resolve the dependency without updating the id.

Answer 5

please add the repository , tag inside the repositories tag like below

<repositories>
        <repository>
            <id>Spark repository</id>
            <url>http://www.sparkjava.com/nexus/content/repositories/spark/</url>
        </repository>
    </repositories>

Answer 6

The last versions (2.1 and later) of Spark only need the dependency defined inside the pom.xml file

<dependency>
    <groupId>com.sparkjava</groupId>
    <artifactId>spark-core</artifactId>
    <version>2.1</version>
</dependency>

the repository definition is not longer required

Answer 7

use this latest repository. http://mvnrepository.com/artifact/org.apache.spark/spark-core_2.10/1.6.0

<dependency>
    <groupId>org.apache.spark</groupId>
    <artifactId>spark-core_2.10</artifactId>
    <version>1.6.0</version>
</dependency>

Answer 8

use this, and also make sure you change spark library to version 2.11.x in eclipse project build path
