After Creating a New Project now its time for the Code Coverage Analysis setup using the SCCT. All the instructions about the SCCT setup were given by the original publisher. I would like to give you a detailed step level setup explanation which makes your path easy for setup.
Set up for SCCT tool.
1. Create plugins folder as shown in below image.

Add the following code to project\plugins\Plugins.scala

import sbt._

class Plugins(info: ProjectInfo) extends PluginDefinition(info) {

val scctRepo = "scct-repo" at "http://mtkopone.github.com/scct/maven-repo/"

lazy val scctPlugin = "reaktor" % "sbt-scct-for-2.8" % "0.1-SNAPSHOT"

}

2. Project definition \project\build\MyFirstProject.scala , should extent reaktor.scct.ScctProject

import sbt._

import reaktor.scct.ScctProject

class AnilsProject(info: ProjectInfo) extends DefaultProject(info) with ScctProject

{

lazy val hi=task {println("This is Anils First New Project"); None}

}

3. Enter in to the project directory
4. Type sbt and press enter

5. Type reload and press enter (necessary only when code is changed or some new files added)
6. Type update and press enter(only when code is changed or some new files added)

7. Type run and press enter.

8. Type test-coverage and press enter
if everything goes fine you see below output

Surprising, Its says that there are no tests to run. Its right we did not write any code for test until now.
9. Add the below code to the file project/build/MyFirstProject.scala
val scalaTest = "org.scalatest" % "scalatest" % "1.2"
val scalaCheck = "org.scala-tools.testing" % "scalacheck_2.8.0" % "1.7"

10. Update source code src/main/scala

11. Update source code for test in src/test/scala

12. now go to terminal type , reload and enter, update and enter
13. Type test-coverage and press enter.

14. To check the test output open /target/scala_2.8.1/coverage-report/index.html

It wasted me a lot of time in setting up the interface to run simple tests. there is no any written manual for the new bees to guide through the process. This struggle with all these setup inspired me to present a guide for the persons who are new to use Scala, SBT, ScalaCheck, SCCT,

enjoy.....

Creating a new project and its definition in SBT - Ubuntu 11.10

I modified or organized the original content...
Before creating a new project the sbt should be setup to launch it from any directory. To do it follow the [2-5] for Ubuntu 11.10

1. Choose your own directory to create a new project
2. Using Terminal, enter into the directory where you planned to create a new project

3. Type sbt into the terminal, if the sbt launch is set properly, you see the below image content

4.It will ask you, create a new project? (y/N/s) Type y and press enter

5. The project has been successfully created, you can check it by visiting the directory where you created the new project, You could see the four folders as shown in the right side of the top image.

6. let us start with an example code, to test if our new project works fine. Copy the below code to the directory src\main\scala

object Anil{

def main(args:Array[String]){

println("\n\n Hello Anil, You program has been successfully Executed \n\n ")

}

7. From Terminal go to directory

8. Type sbt and press enter.

9. Type reload and press enter.

10.Type update and press enter.

11. Type run and press enter.

If everything goes fine you could see the output displayed in blow image

12. Configure sbt by creating project definition using a scala file in to the directory project\build\MyFirstProject.scala

import sbt._

class AnilsProject(info: ProjectInfo) extends DefaultProject(info) {

lazy val hi=task {println("This is Anils First New Project"); None}

}

13. Type hi in command prompt, you will see...

By now, You know how to create a new project, configure SBT by creating a project definition, program an example in Scala and successfully execute it.

Good Luck with the rest.

enjoy the rest of your journey with Scala using SBT

lazy val hi=task {println("This is Anils First New Project"); None}

}

3. Enter in to the project directory (In my case) c:\Users\anil\anil\
4. Type sbt and press enter
5. Type reload and press enter (necessary only when code is changed or some new files added)
6. Type update and press enter(only when code is changed or some new files added)
7. Type test-coverage and press enter.
if everything goes fine you see below output

8. To check the test output open /target/scala_2.9.1/coverage-report/index.html

All the below existing content are the modified and organised content of the above original publishers

Important: Versions of Java, Scala and SBT, check the image below, click it to enlarge...

Instructions for Setup:

1. Download acumen-10.12.13.zip , Extract and rename it to acumen for easy access from command promt

2. Download sbt-launch-0.7.4.jar , and rename it to to sbt-launch.jar. Make sure that Java is already installed and set to path

3. Create a batch file sbt.bat and paste the below code to sbt.bat

set SCRIPT_DIR=%~dp0
java -Xmx512M -jar "%SCRIPT_DIR%sbt-launch.jar" %*

4. Place the sbt.bat and sbt-launch.jar files in same folder

5. Put sbt.bat on path, so that you can launch sbt in any directory by entering sbt from command prompt

6. Open Command Prompt and enter in to the acumen/sources, see image below

8. Now launch SBT by entering sbt from the acumen/sources directory , see image below...

9. Type reload and press enter in the command prompt, see image below...

10. Type update and press enter in the command prompt, see image below ....

11. Type run and press enter in the command prompt, if everything goes fine like me, now you see the compiled and run acumen output, see image below...

Acumen Development Setup In Ubuntu 11.10

2012-02-25T11:26:00.000-08:00

Instructions for Development setup:

Download the Acumen-10.12.13.zip , extract and rename it to acumen for easy access from terminal.
Download sbt-launch-0.7.4.jar and rename it to sbt-launch.jar.
Write the below script to a file to run the jar
Hint: gedit from terminal open text editor, copy the above script and save it as sbt
```

```
Make the script in sbt file executable
Hint :
```
anil@ubuntu:~$ chmod u+x ~/bin/sbt
```
Place the sbt-launch.jar and sbt files to bin
Hint: use the below commands from the location file, I used Home directory
```
anil@ubuntu:~$ sudo mv sbt-launch.jar /bin
```
```
anil@ubuntu:~$ sudo mv sbt /bin
```
In the terminal, enter in to the acumen/sources
```
anil@ubuntu:~$ cd acumen/sources
```
Launch sbt from acumen/sources as shown below
```
anil@ubuntu:~/acumen/sources$ sbt
```
Enter reload from terminal
```
> reload
```
Enter update from terminal

Struggle with Mac

2012-02-24T10:24:00.001-08:00

As a new bee to Mac, it was difficult to use it for some development in technical stuff . All of a sudden If my windows system does not suit for my application development, I can not replace it by a Mac. So I decided to use Virtual Machine on Windows 7 to run Mac X OS. I tried downloading a couple of versions like Leopard, Snow Leopard, Lion. It consumed a lot of time to fix Mac on Windows 7 due to hardware limitations for the Mac X OS , But finally I could able to run Mac X OS Leopard 10.5.5 on VMWare in my Windows 7.

Initially the Mac is not supported to run sbt, Mac that I run misses some applications like Xcode, MacPort. After Installation of Xcode and MacPort in Mac, I could able to install sbt with the following command .

$ sudo port install sbt

after installing sbt . I want to show you what I got, an error

After wasting 2 days of time in exploring possibilities of running mac in Wndows7, Initially it went well, but finally the Mac did not boot due to some hardware limitations. I am tied and gave it up .
Now I decided to jump to Ubuntu 11.10. I made my system dual boot this time, Windows7 and Ubuntu

errors

2012-02-22T17:31:00.000-08:00

Errors that usually found when everything does not go fine

In Ubuntu,

when wrong version of sbt is installed

In Windows

Install ScalaCheck

2012-02-21T15:53:00.000-08:00

Open the Command Prompt, go to the Scala installed locataion
c:\scala\bin
Use the the command
c:\scala\bin sbaz install scalacheck

Install Scala in Windows 7

2012-02-21T15:42:00.000-08:00

Before Installing Scala, make sure that Java 1.5 or higher version is already installed in the system.

Download Scala 2.9.1 Stable Release for Windows and Install in C:\scala as shown in the below picture.

To work with the Installed Scala from the command prompt ,set the path for both Java and Scala.

Open Command Prompt and type javac, if everything is set fine you see the below output

Similarly for Scala,
