1. Download and install the required build tools:

• Install J2SE 1.7 JDK and set the environment variable JAVA_HOME accordingly.
• Install Maven and set the environment variable MAVEN_HOME accordingly.

2. Add $JAVA_HOME/bin and $MAVEN_HOME/bin to your PATH.

3. Download the NEST source code and unpack into $MY_PROJECTS/nest.

4. Open a Command Prompt or Terminal and CD into the NEST source code folder

5. To build NEST from source: Type mvn compile

Get the open source Community Edition of IntelliJ IDEA from JetBrains

IntelliJ IDEA users

1. Build IDEA project files for NEST: Type mvn compile idea:idea

2. In IDEA, go to the IDEA Main Menu/File/Open Project and open the created project file $MY_PROJECTS/nest/nest.ipr

Eclipse users

1. Build Eclipse project files for NEST: Type mvn compile eclipse:eclipse

2. From Eclipse, click on Main Menu/File/Import

3. Select General/Existing Project into Workspace

4. Select Root Directory $MY_PROJECTS/nest and press Finish

5. Set the M2_REPO classpath variable:

• Select New... and add variable M2_REPO
• Select Folder... and choose the location of your Maven local repository, e.g ~/.m2/repository

Note: In Eclipse, some purposely malformed XML in a unit test may prevent you from building the source. Simply delete these files module-no-xml.xml and module-malformed-xml.xml in $MY_PROJECTS/nest/beam/ceres-0.x/ceres-core/src/test/resources/com/bc/ceres/core/runtime/internal/xml

For both IDEA and Eclipse, use the following configuration to run DAT as an Application:

- (For eclipse set the Project to nest-bootstrap)
- Main class: com.bc.ceres.launcher.Launcher
- VM parameters: -Xmx1024M -Dceres.context=nest
- Program parameters: none
- Working directory: nest source code folder/output
- Use classpath of module nest-bootstrap (For eclipse click on user entry, press the button add project and select nest-bootstrap)

To package a distribution for all platforms: mvn package assembly:assembly
