Example 21 with Path

use of com.google.devtools.build.lib.vfs.Path in project bazel by bazelbuild.

the class PackageFunctionTest method testGlobWithExternalSymlink.

   * Tests that a symlink to a file outside of the package root is handled consistently. If the

   * ExternalFileAction#DEPEND_ON_EXTERNAL_PKG_FOR_EXTERNAL_REPO_PATHS} to {@code
   * ExternalFileAction#ASSUME_NON_EXISTENT_AND_IMMUTABLE_FOR_EXTERNAL_PATHS} then foo/link.sh
   * should no longer appear in the srcs of //foo:foo. However, either way the srcs should be the
   * same independent of the evaluation being incremental or clean.
