basedir

Summary

The basedir macro returns the absolute path to the base directory of the current processor (project, workspace, or build context). This is the root directory from which relative paths are resolved.

Syntax

${basedir}

Parameters

None - this macro takes no parameters.

Behavior

• Returns the absolute path to the base directory
• The base directory is the root context for resolving relative file paths
• Throws an exception if no base directory has been set (rare edge case)

Examples

Get the current project’s base directory:

project.root=${basedir}

Build a path relative to the base directory:

resources.dir=${basedir}/src/main/resources

Reference files using the base directory:

Bundle-Icon: ${basedir}/icon.png

Use Cases

• Building absolute paths to project resources
• Referencing files in build configurations
• Creating platform-independent path references
• Debugging path resolution issues
• Documentation and logging of project locations

Notes

• The base directory is typically the project directory for bnd projects
• In workspace contexts, it may be the workspace root
• The path separator used in the returned path is platform-specific
