Bamboo variables
Variables can be used to make values available when building plans in Bamboo.
- Build-specific variables are evaluated by Bamboo dynamically at build time. The source of a build-specific variable can either be a Bamboo property or one of the default plugins (assuming it is enabled).
- Deployment variables are available when deploying a project.
- System variables also apply across your entire Bamboo instance and inherit their values from system or environment variables of the same name.
- Global variables are defined across your entire Bamboo instance, and have the same (static) value for every plan that is built by Bamboo. See Defining global variables.
- Project variables are defined for specific projects. Project variables can override global variables with the same name. See Defining project variables.
- Plan variables are similar to global variables, but are defined for specific plans. Plan variables override global and project variables with the same name. You can also override a plan variable for a build if you trigger the build manually. See Defining plan variables.
Using variables
Variables can be used in all fields of a task or deployment, with the exception of password fields. Use the following format when referencing a variable:
${bamboo.variableName}
You can override a plan variable for a build, if you trigger the build manually. See Triggering a plan build manually.
You can reference a variable from another variables, e.g. consider having the following variables:
var1 = Hello
var2 = world
You can create another variable which references the two other one.
${bamboo.var1} ${bamboo.var2}!
Bamboo will resolve the variable as Hello World!
You can:
- reference a global or context specific variable in a build plan or deployment project
- reference a variable which references another one, deep recursion is allowed
There are couple of limitations:
- referencing a variable which isn't defined is an error, whole build or deployment will fail if you reference such variable
- cycles are not allowed and are considered as build or deployment project error.
Defining custom variables
You can define your own custom variables, using a similar format to that above, however you cannot create a variable name that is already in use by Bamboo.
For information on how to define your own variables in Bamboo, see:
On this page:
Build-specific variables
The following build-specific variables are available by default:
- System variables apply across your entire Bamboo instance and inherit their values from system or environment variables of the same name.
- In the variable names from the table, <position> is an optional parameter that specifies the position of the repository in the plan's repository list. If omitted, the first repository in the list is used.
- Third-party repository plugins can expose their own variables.
Build-specific variable | Description |

- System variables also apply across your entire Bamboo instance and inherit their values from system or environment variables of the same name.
- In the variable names from the table above, <position> is an optional parameter that specifies the position of the repository in the plan's repository list. If omitted, the first repository in the list is used.
- Third-party repository plugins can expose their own variables.
Build dependency variables
The following build dependency variables are also available:
Build-specific variable | Description |
---|---|
bamboo.dependency.parent.# | Allows a child build to query the build key of the triggering parent build, where # represents the position in the build tree - 0 at the top, 1 the following, and so on. The ${bamboo.dependency.parent.0} variable can be viewed in the child plan's metadata tab. |
bamboo.dependency.parent.total | The total # of parent builds. |
Deployment variables
Variables later in the following list override the previous ones in case of repeating names:
- global variables
- project variables of the plan linked to the deployment project
- plan variables of the plan linked to the deployment project
- release variables as defined below
- user variables defined at the environment level
- the autogenerated variables in the following table:
Variable | Description |
---|---|
bamboo.agentId | The id of the agent that the deployment is executed on. |
bamboo.agentWorkingDirectory | The path to the working directory on the agent. This is not the same as the Bamboo working directory. |
bamboo.build.working.directory | The path to the working directory for Bamboo. This is used by both the build plan and the deployment project. |
bamboo.deploy.environment | The name of the environment that the release is to be deployed to. |
bamboo.deploy.project | The name of the deployment project. |
bamboo.deploy.rollback | True if the release being deployed is older than the release being replaced. |
| The name of the release that is being deployed. Either .release or .version can be used. Both return the name of the release being deployed. |
| The name of the release that is being replaced (if available). Either .release or .version can be used. Both return the name of the release being replaced. |
bamboo.resultsUrl | The URL to the screen in Bamboo that displays build results. |
bamboo.triggerReason.key | The trigger key that caused the deployment to launch. For example:
|
You can generate variables of your own, using a similar format, however you cannot create a variable that is already in use by Bamboo. See Defining deployment environment variables for more information.
Releases variables
Bamboo makes the following types of variables available for deployment releases:
- Snapshots of values of global variables.
- Snapshots of values of project variables.
- Snapshots of values of plan variables.
- Snapshots of values of repository variables.
- The autogenerated release variables in the following table:
Variable | Description |
---|---|
bamboo.buildNumber | The build result from which the release is created. |
bamboo.buildResultKey | The key of the build result from which the release is created e.g. KUNG-FOO-35 |
bamboo.planKey | The key of the plan related to the release e.g. KUNG-FOO |
bamboo.planName | The name of the plan related to the release e.g. Kung - Foo |
bamboo.shortPlanKey | The short key of the plan related to the release (without project part), e.g. MAIN |
bamboo.shortPlanName | The plan's name without project part, e.g. Some plan name |
Note that several of the variables in the above table are actually those associated with the build plan. The snapshots mentioned above do not contain password variables.
System variables
The usage format for all system variables is:
${system.<variable>}
For example, if you have a system variable MYPATH=C:\MyPath;
you can use a Bamboo system variable system.MYPATH
which will inherit the same value as the system variable.
In older Bamboo versions using PATH in the Environment Variables field (of a Script task) doesn't set the windows PATH variable, whereas using Path sets Path and PATH in cmd shell.
Using variables in bash
Bamboo variables are exported as bash shell variables. All full stops (periods) are converted to underscores. For example, the variable bamboo.my.variable
is $bamboo_my_variable
in bash. This is related to File Script and Inline Script tasks.
Jira applications variables
Note that these variables can be accessed from a Bamboo build only when that build was triggered by releasing a version in Jira Software.
Jira variable | Description |
---|---|
${bamboo.jira.baseUrl} | The URL of your Jira application server. |
${bamboo.jira.projectKey} | The key of the triggering Jira application project. |
${bamboo.jira.projectName} | The name of the triggering Jira application project. |
${bamboo.jira.version} | The release version of the triggering Jira application project. |
${bamboo.jira.username} | The username of the user who triggered the release build. |
Examples
Maven examples
For example, you may want your Maven 2 version to be determined by Bamboo. In Maven 2 pom.xml
you may have:
...
<groupId>com.atlassian.boo</groupId>
<artifactId>boo-test</artifactId>
<packaging>jar</packaging>
<version>1.1.${bambooBuildNumber}-SNAPSHOT</version>
...
You can then specify the following in the Goal field of your build plan:
clean package -DbambooBuildNumber=${bamboo.buildNumber}
When the command runs, Bamboo will replace the buildNumber
with the actual number (e.g. 1102), which will be passed to the underlying Maven build to use. The command will then produce a jar that looks like this: boo-test-1.1.1102-SNAPSHOT.jar
.
Ant examples
You can then specify the following in the Target field of your build plan:
-f build.xml -DbambooBuildNumber=${bamboo.buildNumber}
When the command runs, Bamboo will replace the buildNumber
with the actual number (e.g. 1102), which will be passed to the underlying Ant build to use.
Specifying capabilities as variables
You can also specify a capability to be used in a similar way to a global variable.
The format of the capability should be as follows:
${bamboo.capability.<capability_key>}
For example,
Custom
${bamboo.capability.<capability_key>}
JDK
${bamboo.capability.system.jdk.<jdk_label>}
Builder
${bamboo.capability.system.builder.<builder_type>.<builder_label>} e.g. ${bamboo.capability.system.builder.maven.Maven1}
If you select a capability, the specific capability key will be contained in the URL.
Please note, the space characters in the URL will be replaced with "+" characters. We recommend that you do not use capability labels with space characters, if you wish to use them as variables. A possible solution for space characters is to format them with "${}" symbols, however, this does not work in all cases.
Using capabilities
Global and Build-Specific Variables can be used in specific fields of your build plan, as specified above. For capabilities,
- System capabilities are available to all of these fields, (i.e. global and build-specific).
- Agent capabilities (i.e. agent-specific and shared/server capabilities) are available only to the build-specific fields. (i.e. not available to Repository URL, CVS Root or Branch name.)
For example,
If you wanted to specify a system variable, but have it set to different values on each agent, do the following:
Set the following as a system environment variable field on the Builder tab:
${bamboo.capability.thatsystemvariable}
- Specify the system environment variable as a custom capability on each of your agents, and set to the capability to the different values, as desired.
Deprecated variables
The following variables are deprecated and are subject for removal in future Bamboo releases:
Generic repository variables | |
---|---|
bamboo.repository.revision.number | The revision number. If many repositories are linked to the plan, the variable stores the revision number of the last repository in the list. |
bamboo.repository.branch.name | The repository branch name (for Bamboo version 4.2 or later). If many repositories are linked to the plan, the variable stores the branch name of the first repository in the list. |
bamboo.repository.previous.revision.number | The previous revision number (might not exist, for example for the initial build). If many repositories are linked to the plan, the variable stores the previous revision number of the first repository in the list. |
Subversion | |
bamboo.custom.svn.revision.number | The revision number. |
bamboo.custom.svn.lastchange.revision.number | The last changed revision number. |
bamboo.custom.svn.username | User name used for repository authentication. |
