Method Detail

getOutputClasspathJars

public static com.google.common.collect.ImmutableSet<SourcePath> getOutputClasspathJars(JavaLibrary javaLibraryRule,
                                                                                        Optional<SourcePath> outputJar)

getTransitiveClasspathDeps

public static com.google.common.collect.ImmutableSet<JavaLibrary> getTransitiveClasspathDeps(JavaLibrary javaLibrary)

getClasspathDeps

public static com.google.common.collect.ImmutableSet<JavaLibrary> getClasspathDeps(Iterable<BuildRule> deps)

Include the classpath entries from all JavaLibraryRules that have a direct line of lineage to this rule through other JavaLibraryRules. For example, in the following dependency graph:

        A
      /   \
     B     C
    / \   / \
    D E   F G

 

If all of the nodes correspond to BuildRules that implement JavaLibraryRule except for B (suppose B is a Genrule), then A's classpath will include C, F, and G, but not D and E. This is because D and E are used to generate B, but do not contribute .class files to things that depend on B. However, if C depended on E as well as F and G, then E would be included in A's classpath.

getClasspathsFromLibraries

public static com.google.common.collect.ImmutableSet<SourcePath> getClasspathsFromLibraries(Iterable<JavaLibrary> libraries)

Given libraries that may contribute classpaths, visit them and collect the classpaths.

This is used to generate transitive classpaths from library discovered in a previous traversal.

getAllReachableJavaLibraries

public static com.google.common.collect.ImmutableSet<JavaLibrary> getAllReachableJavaLibraries(Iterable<? extends BuildRule> rules)

Return the classpath, including traversing any provided_deps edges and non-java edges
