Examples with Label com.google.devtools.build.lib.cmdline.Label used on opensource projects

Example 1 with Label

use of com.google.devtools.build.lib.cmdline.Label in project bazel by bazelbuild.

the class Package method makeNoSuchTargetException.

protected NoSuchTargetException makeNoSuchTargetException(String targetName, String suffix) {

Example 2 with Label

use of com.google.devtools.build.lib.cmdline.Label in project bazel by bazelbuild.

the class PackageFactory method skylarkifyValue.

   * such as string instead of label, SkylarkList instead of List,
   * Returns null if we don't want to export the value.
   *
   * <p>All of the types returned are immutable. If we want, we can change this to
   * immutable in the future, but this is the safe choice for now.
