Example 6 with Command

use of com.google.copybara.shell.Command in project copybara by google.

the class PatchingOptions method patchWithGnuPatch.

private void patchWithGnuPatch(Path rootDir, byte[] diffContents, int stripSlashes, boolean verbose, boolean reverse, Map<String, String> environment) throws IOException {
    ImmutableList.Builder<String> params = ImmutableList.builder();
    // Show verbose output unconditionally since it is helpful for debugging issues with patches.
    // When the patch file doesn't match the file exactly, GNU patch creates backup files, but we
    // disable creating those as they don't make sense for Copybara and otherwise they would need
    // to be excluded
    // See: http://b/112639930

    if (reverse) {
        params.add("-R");
    }
    // Only apply in the direction requested. Yes, -R --forward semantics is that it reverses
    // and only applies if can be applied like that (-R will try to apply reverse and forward).
