Buiding Hadoop with Eclipse / Maven - Missing artifact jdk.tools:jdk.tools:jar:1.6

I am trying to import cloudera's org.apache.hadoop:hadoop-client:2.0.0-cdh4.0.0 from cdh4 maven repo in a maven project in eclipse 3.81, m2e plugin, with oracle's jdk 1.7.0_05 on win7 using 

<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-client</artifactId>
    <version>2.0.0-cdh4.0.0</version>
</dependency>

however, I get the following error:

The container 'Maven Dependencies' references non existing library 'C:\Users\MyUserId\.m2\repository\jdk\tools\jdk.tools\1.6\jdk.tools-1.6.jar'

more specific, maven states that the following artifact is missing

Missing artifact jdk.tools:jdk.tools:jar:1.6

How to solve this?

Solution

  • jdk.tools:jdk.tools (or com.sun:tools, or whatever you name it) is a JAR file that is distributed with JDK. Usually you add it to maven projects like this:

    <dependency>
    <groupId>jdk.tools</groupId>
    <artifactId>jdk.tools</artifactId>
    <scope>system</scope>
    <systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>

    See, the Maven FAQ for adding dependencies to tools.jar

    Or, you can manually install tools.jar in the local repository using:

    mvn install:install-file -DgroupId=jdk.tools -DartifactId=jdk.tools -Dpackaging=jar -Dversion=1.6 -Dfile=tools.jar -DgeneratePom=true

    and then reference it like Cloudera did, using:

    <dependency>
    <groupId>jdk.tools</groupId>
    <artifactId>jdk.tools</artifactId>
    <version>1.6</version>
</dependency>
