IDE introduced jblas

"Spark machine learning", Section 4.4.2 "Recommended goods", need to use jblas package, import org.jblas.DoubleMatrix, suggesting the package does not exist

Online searching for a solution, the solution is divided into the following categories:

The first: the compiler used to import external jar package.

The second: first jar package copied to the lib folder, and then edit spark-env.sh file import with export statement (not tried)

Third: spark has a jars in the root directory folder , there are a variety of jar package directly copy the jar package to this directory , first download jblas-1.2.3.jar, extract the jar to the next folder, then IDEProject Structure -> GlobalLibraries - "+ add to jar it, there is a re-import

Attached: jblas-1.2.3.jar Download

Fourth: the IDE add dependencies in the pom.xml

<dependency>
  <groupId>org.jblas</groupId>
  <artifactId>jblas</artifactId>
  <version>1.2.4</version>
</dependency>

Pro-test work well
