Example 1 with DistributionType

use of com.google.devtools.build.lib.packages.License.DistributionType in project bazel by bazelbuild.

the class BuildTool method validateLicensingForTargets.

/**
   * Takes a set of configured targets, and checks if the distribution methods
   * declared for the targets are compatible with the constraints imposed by
   * their prerequisites' licenses.
   *
   * @param configuredTargets the targets to check
   * @param keepGoing if false, and a licensing error is encountered, both
   *        generates an error message on the reporter, <em>and</em> throws an
   *        exception. If true, then just generates a message on the reporter.
   * @throws ViewCreationFailedException if the license checking failed (and not
   *         --keep_going)
