Example 1 with ExportDependencies

use of com.facebook.buck.rules.ExportDependencies in project buck by facebook.

the class Project method walkRuleAndAdd.

/**
   * Walks the dependencies of a build rule and adds the appropriate DependentModules to the
   * specified dependencies collection. All library dependencies will be added before any module
   * dependencies. See {@code ProjectTest#testThatJarsAreListedBeforeModules()} for details on why
   * this behavior is important.
