Examples with ExecutableSymlinkAction com.google.devtools.build.lib.analysis.actions.ExecutableSymlinkAction used on opensource projects

Example 1 with ExecutableSymlinkAction

use of com.google.devtools.build.lib.analysis.actions.ExecutableSymlinkAction in project bazel by bazelbuild.

the class ShBinary method create.

@Override
public ConfiguredTarget create(RuleContext ruleContext) throws RuleErrorException {
    ImmutableList<Artifact> srcs = ruleContext.getPrerequisiteArtifacts("srcs", Mode.TARGET).list();
    if (srcs.size() != 1) {
        ruleContext.attributeError("srcs", "you must specify exactly one file in 'srcs'");
        return null;
    }
    Artifact symlink = ruleContext.createOutputArtifact();
    // Note that src is used as the executable script too
    Artifact src = srcs.get(0);
    // The interpretation of this deceptively simple yet incredibly generic rule is complicated
    // by the distinction between targets and (not properly encapsulated) artifacts. It depends
    // on the notion of other rule's "files-to-build" sets, which are undocumented, making it
    // impossible to give a precise definition of what this rule does in all cases (e.g. what
    // happens when srcs = ['x', 'y'] but 'x' is an empty filegroup?). This is a pervasive
    // problem in Blaze.
    ruleContext.registerAction(new ExecutableSymlinkAction(ruleContext.getActionOwner(), src, symlink));
    NestedSet<Artifact> filesToBuild = NestedSetBuilder.<Artifact>stableOrder().add(src).add(symlink).build();
    Runfiles runfiles = new Runfiles.Builder(ruleContext.getWorkspaceName(), ruleContext.getConfiguration().legacyExternalRunfiles()).addTransitiveArtifacts(filesToBuild).addRunfiles(ruleContext, RunfilesProvider.DEFAULT_RUNFILES).build();

    return new RuleConfiguredTargetBuilder(ruleContext).setFilesToBuild(filesToBuild).setRunfilesSupport(runfilesSupport, symlink).addProvider(RunfilesProvider.class, RunfilesProvider.simple(runfiles)).build();
