This API allows IDEs to integrate with Maven deeper than it would be possible by just using regular Maven/Mojo API.
It supports
- incremental builds e.g. allows to query which files have been touched since last build
- fine-grained error/info markers (referring to specific files in particular line numbers)
- notifications about updated files
The default implementation shipping with this artifact is supposed to impose minimal overhead. It doesn't support incremental build and acts directly on the file system. Errors and warning are just logged through SLF4J.
M2Eclipse is using this API for supporting both incremental builds and fully integrated error markers in Eclipse. They maintain information for Mojo developers at Making Maven Plugins Compatible.
Currently only versions up to 0.0.7 (with old Maven coordinates org.sonatype.plexus:plexus-build-api) are supported, this limitation is tracked in Issue 944.
The project was relocated from https://github.com/sonatype/sisu-build-api. Also its Maven coordinates changed from org.sonatype.plexus:plexus-build-api to org.codehaus.plexus:plexus-build-api, the API is still the same, though.
