Example 1 with Sha1HashCode

use of com.facebook.buck.util.sha1.Sha1HashCode in project buck by facebook.

the class AaptPackageResourcesIntegrationTest method testEditingLayoutChangesPackageHash.

    // This is too low-level of a test.  Ideally, we'd be able to save the rule graph generated
    // by the build and query it directly, but runBuckCommand doesn't support that, so just
    // test the files directly for now.
