Cannot run program "git.exe": CreateProcess error=2, The system cannot find the file specified I solve this problem after installing Git. A new project folder created.

Download and install git on the machine before cloning from Intellij. Here's the link

Answer 2

Do you want to use EJML, or do you want to work on EJML? It's unlikely you want to clone it.

Instead, create a project and add EJML as a dependency. Using Maven, add this to your pom.xml:

<dependency>
  <groupId>org.ejml</groupId>
  <artifactId>ejml-all</artifactId>
  <version>0.33</version>
</dependency>

Using Ivy, add this to ivy.xml:

<dependency org="org.ejml" name="core" rev="0.33"/>

Using Gradle, add this to build.gradle:

compile group: 'org.ejml', name: 'core', version: '0.33'

Update: I tried adding it to a project of mine, and while the EJML web site mentions version 0.34, Maven Central only seems to have 0.33 currently.

To create a project in IntelliJ IDEA from scratch:

• Click "Create New Project"
• Make it a "Java Project" (default), and click Next
• Click Next to bypass creating from a template
• Give the project a thoughtful name, like "Sparse", and click Finish
• Right-click on the project at the upper left and click "Add Framework Support..."
• Check "Maven" and click "OK"

• In the pom.xml, add these lines after the :

  org.ejml ejml-all 0.33

• IntelliJ IDEA will prompt that the Maven project needs to be imported. Allow it.

On the left side under the project you can open src/main/java in the tree and right-click on java and choose New > Java Class and you should be ready to go.
