ExternalLookup

sbt.internal.inc.ExternalLookup
trait ExternalLookup extends Lookup

Defines a hook interface that IDEs or build tools can mock to modify the way Zinc invalidates the incremental compiler. These hooks operate at a high-level of abstraction and only allow to modify the inputs of the initial change detection.

def lookupAnalyzedClass(binaryClassName: String, file: Option[VirtualFileRef]): Option[AnalyzedClass]

Find the external AnalyzedClass (from another analysis) given a class name and, if available, the jar file (or class file) the class comes from.

Find the external AnalyzedClass (from another analysis) given a class name and, if available, the jar file (or class file) the class comes from.

Attributes

Returns

The AnalyzedClass associated with the given class name, if one is found. None => Found class somewhere outside of project. No analysis possible. Some(analyzed) if analyzed.provenance.isEmpty => Couldn't find it. Some(analyzed) => good

def shouldDoEarlyOutput(analysis: CompileAnalysis): Boolean

Used to override whether we should proceed with making an early output.

Used to override whether we should proceed with making an early output.

By default we do not make an early output in the presence of any macros because macro expansion (in a downstream subproject) requires the macro implementation to be present in bytecode form, rather than just just a pickle-containing JAR.

If you're careful micromanaging the separation of macro implementations (e.g. def impl(c: Context) = ...) from macro definitions (e.g. def foo: Unit = macro Foo.impl) you can safely override this.
