For Scala developers, it is very important to check the Scala version in the terminal. To make sure that your system is compatible with libraries, frameworks, etc., and to resolve any specific issues that might arise during programming, knowing the Scala version installed on a computer is vital. Within this tutorial, we shall provide you with an illustrated explanation of how to check the Scala version on various operating systems using the command line.
How to Check Scala Version:
1. Linux/Mac OS X:
Firstly, open a terminal application and enter the following command:
Code:
scala -version
It is this command that asks for the Scala executable’s version information and displays it on the terminal.
Output:
scala 3.4.0
2. Windows:
If you are using Windows then use the following steps to check your Scala version.
- Press Win + R to open the Run dialog box, type cmd in the box, and press Enter.
- Enter the following command:
Code:
scala -version
It is this command that queries the Scala executable for its version information as well as displays it on Command Prompt.
Output:
Scala code runner version 3.4.0
Key Points:
- Whether they are working on Scala projects or simply using libraries and tools that have been written in it, verifying the compatibility of their own systems with different Scala versions is significant.
- The scala -version command will return information about its version.
- It usually prints out additional details such as code runner’s name together with scala factual number at its end.
Description:
1. Linux/Mac OS X:
To fetch the installed Scala version by command |scala -version| in Terminal, Linux and macOS programs are used. This command specifically asks the scala executable for its verion details and while doing so prints it at Terminal. The output is comprised of scala.java language’s release number indicating what scala level has been installed.
2. Windows:
Moreover, it is done using Command Prompt in Windows systems to find the Scala version which is similar to Linux and macOS. This command works just like its Linux and macOS counterpart by presenting the scala version details on the command prompt screen.
Conclusion:
On a final note, no matter the OS you are using, checking Scala’s version through terminal can be done easily. Once you have executed scala -version, the installed scala version will be readily available thus ensuring compatibility with other tools and making development workflows seamless. This easy and necessary move can help you develop your Scala projects more efficiently as well as promptly address issues related to versions.
