Class FrontendOnlyJavacTask

java.lang.Object

com.sun.source.util.JavacTask

com.facebook.buck.jvm.java.plugin.adapter.BuckJavacTask

com.facebook.buck.jvm.java.abi.source.FrontendOnlyJavacTask

All Implemented Interfaces:

Callable<Boolean>, JavaCompiler.CompilationTask

public class FrontendOnlyJavacTask
extends BuckJavacTask

An implementation of JavacTask that implements only the frontend portions of the task, using only the parse phase of the underlying compiler and without requiring a complete classpath. This effectively does the same thing as the Enter phase of the compiler (see http://openjdk.java.net/groups/compiler/doc/compilation-overview/index.html), but applying heuristics when dependencies are missing. This necessarily requires some assumptions to be made about references to symbols defined in those dependencies. See the documentation of com.facebook.buck.jvm.java.abi.source for details.
