Managing Build Environments

 In continuum, Build Environments allow you to create and manage multiple build
 configurations. Once you have defined the Build Environments you can configure
 project Build Definitions or {{{./builddefTemplate.html}Build Definition
 Templates}} to use them.

 <Note: Build Environments affect the versions of specific tools used to execute
 builds and their environments. They are not intended to replace things like
 Maven build profiles.>

*Build Environments

 Build Environments are named groupings of {{{./builder.html}Installations}}. By
 grouping the collection of Tools and Environment Variables, you define a
 configuration that can be used to build a project. To define a Build
 Environment, you specify a human friendly name and add one or more
 Installations. Once defined, the Build Environment is available for use. You
 can then specify what Build Environment to use in your project's Build
 Definitions or in your Build Definition Templates. When continuum detects that
 a project needs to be built, it uses the Tool Installations to construct the
 paths to the expected executables (ie. Maven build definitions construct paths
 to the mvn executable and the java executable). Additional Installations are
 translated into name/value pairs that are passed through to the constructed
 command's environment.

  As of Continuum 1.2.1, build environments can be used in releasing projects.
  This is set upon supplying the release prepare parameters during the
  {{{../user_guides/release/prepare.html} Release preparation}} of the project.

**Creating a Build Environment

  From the menu, choose the 'Build Environments' entry

[../images/buildenv-menu.png] Build Environment Menu

  Enter a name

[../images/buildenv-add.png] Add Build Environment

** {Attach Build Agent Group to a Build Environment}

  The list box contains all available Build Agent Groups. The list box will only be visible if Distributed Builds is enabled in the {{{./configuration.html}General Configuration}} Page

[../images/profile-build-agent-group.png] Add Build Agent Group to Build Environment

**Attaching the related Installations

 When editing a Build Environment, the Installation list box contains all
 defined Installations. You can only specify a single Tool Installation per type
 (jdk, maven, maven2, ant). However, you may specify multiple Environment
 Variable Installations.

**Setting a Build Definition's Build Environment

 The way you configure builds to use your newly created Build Environments is by
 setting it in either a project Build Definition or in the continuum Build
 Definition Templates. The following example sets the Build Environment of a
 specific project's Build Definition.

**Installations used in Notification mail

  Build notifications send along information about the environment in which the
  project was built.

  * Java Home version : coming from $JAVA_HOME/bin/java -version.

  * Builder version : coming from builder used version arg (mvn  used -v, ant
  use -version).
