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

Question

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:UsersMyUserId.m2
epositoryjdkoolsjdk.tools1.6jdk.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?

Answer 1

The problem is in the Eclipse Maven support, the related question is here.

Under Eclipse, the java.home variable is set to the JRE that was used to start Eclipse, not the build JRE. The default system JRE from C:Program Files doesn't include the JDK so tools.jar is not being found.

To fix the issue you need to start Eclipse using the JRE from the JDK by adding something like this to eclipse.ini (before -vmargs!):

-vm
C:/<your_path_to_jdk170>/jre/bin/server/jvm.dll

Then refresh the Maven dependencies (Alt-F5) (Just refreshing the project isn't sufficient).
