Install Scala 2.11 In Win7

1. Download Scala 2.11
Http://download.csdn.net/download/u014393736/7107595

The Scala Installation File I downloaded is actually a compressed package. You only need to decompress the file!
Of course, you can also download the msi suffix file on the official website for installation.

The installation process is as follows:

The benefit of downloading the msi version is that the environment variables are automatically configured. Otherwise, you need to manually set two environment variables.
The SCALA_HOME environment variable points to the Scala installation directory.
PATH environment variable, which must contain the value of % SCALA_HOME % \ bin.

2. Install Scala 2.9.2
After the download is complete, execute the scala-2.9.2.msi and follow the prompts to install step by step. I installed it in C: \ scala.

3. Verify
Press Windows key + R key, Enter CMD, and press enter to enter WindowsCMD command line mode.
Type the following command:

Scala

Scala-version

Both commands can

The explicit result is as follows:

Scala installation and operation are normal!

Program test:

Basically normal

4. Install Scala in Eclipse IDE
Scala officially provides three plug-ins that support the Eclipse, NetBeans, and Intellij IDEA development environments. To install the Scala plug-in Eclipse IDE:
Select the menu item Help --> Install New Software... of Eclipse, click "Add", and fill in the following values in Name and Location:
Name: ScalaIDE
Location: http://download.scala-ide.org/releases-29/stable/site
Step by step until the installation is complete.
Restart Eclipse and you can see that the New menu and Windows --> Preferences have Scala options.



5. Notes
Note that the Scala IDE plug-in currently only supports Eclipse 3.6 and 3.7, and does not support the latest Eclipse 4.2. After my tests, it is true that Scala IDE plug-in cannot be installed in Eclipse 4.2.
In addition, Scala officially hopes to adjust the heap memory during Eclipse runtime to more than MB. :
