Example 6 with Fragment

use of com.google.devtools.build.lib.analysis.config.BuildConfiguration.Fragment in project bazel by bazelbuild.

the class BuildConfigurationFunction method getConfigurationFragments.

private Set<Fragment> getConfigurationFragments(BuildConfigurationValue.Key key, Environment env) throws InvalidConfigurationException, InterruptedException {
    // Get SkyKeys for the fragments we need to load.
    Set<SkyKey> fragmentKeys = new LinkedHashSet<>();
    for (Class<? extends BuildConfiguration.Fragment> fragmentClass : key.getFragments()) {
        fragmentKeys.add(ConfigurationFragmentValue.key(key.getBuildOptions(), fragmentClass, ruleClassProvider));
    }
    // Load them as Skyframe deps.
    Map<SkyKey, ValueOrException<InvalidConfigurationException>> fragmentDeps = env.getValuesOrThrow(fragmentKeys, InvalidConfigurationException.class);
    if (env.valuesMissing()) {
        return null;
    }
