Brew untap of an official tap you don’t use (e.g. Homebrew/homebrew-cask) will ensure it’s no longer automatically retapped; brew casks is a new command implemented in Bash to speedily output all casks available to install (like brew formulae) brew info -cask -json=v2 includes whether a cask is outdated and the currently installed versions. The installation of Apache Maven is a simple process of extracting the archive and adding the `bin` folder with the `mvn` command to the `PATH`. Switch maven version. I installed maven by home-brew, and I remembered I already install maven 3.2 and because of the recommendation build issue, I downgraded it to maven 2.2.1. So now my question is how to relink my maven to the higher version. Check my current maven version. “install maven homebrew” Code Answer. Install maven homebrew.

This guide helps in the install and setup of SystemDS from source code.

Windows

Ubuntu 20.04

Java and Maven

First setup java and maven to compile the system note that the java version is 1.8.

Homebrew maven install

Verify the install with:

This should return something like:

Testing

Homebrew Maven Without Openjdk

R is required to be install to run the test suite, since many tests are constructed to comprare output with common R packages.One option to install this is to follow the guide on the following link: https://linuxize.com/post/how-to-install-r-on-ubuntu-20-04/

At the time of writing the commands to install R 4.0.2 are:

See Build the project to compile the code from here.

MAC

Prerequisite install homebrew on the device.

Homebrew mavericks

Then afterwards verify the install:

This should print something like:

Note that if you have multiple java versions installed then you have to change the used version to 8, on both java and javadoc. This is done by setting the environment variable JAVA_HOME to the install path of open JDK 8 :

For running all tests r-base has to be installed as well since this is used as a secondary system to verify the correctness of our code, but it is not a requirement to enable building the project.

See Build the project to compile the code from here.

Build the project

To compile the project use:

Homebrew

The first time you package the system it will take longer since maven will download the dependencies.But successive compiles should become faster.

Now everything is setup and ready to go!To execute dml scripts look at Execute SystemDS

Homebrew Maven

The installation of Apache Maven is a simple process of extracting the archive and adding the `bin` folder with the `mvn` command to the `PATH`.

Detailed steps are:

  • Ensure JAVA_HOME environment variable is set and points to your JDK installation

  • Extract distribution archive in any directory

or

Alternatively use your preferred archive extraction tool.

  • Add the bin directory of the created directory apache-maven-3.8.1 to the PATH environment variable

  • Confirm with mvn -v in a new shell. The result should look similar to

Windows Tips

  • Check environment variable value e.g.

Homebrew Install Maven

  • Adding to PATH: Add the unpacked distribution’s bin directory to your user PATH environment variable by opening up the system properties (WinKey + Pause), selecting the “Advanced” tab, and the “Environment Variables” button, then adding or selecting the PATH variable in the user variables with the value C:Program Filesapache-maven-3.8.1bin. The same dialog can be used to set JAVA_HOME to the location of your JDK, e.g. C:Program FilesJavajdk1.7.0_51

  • Open a new command prompt (Winkey + R then type cmd) and run mvn -v to verify the installation.

Unix-based Operating System (Linux, Solaris and Mac OS X) Tips

  • Check environment variable value
  • Adding to PATH
