Example 2 with ConfigFile

use of com.google.copybara.config.ConfigFile in project copybara by google.

the class QuiltTransformation method copyPatchConfigsToTmpDir.

private ImmutableList<Path> copyPatchConfigsToTmpDir() throws IOException {

    Path patchDir = options.getGeneralOptions().getDirFactory().newTempDir("inputpatches");
    for (ConfigFile patch : patchConfigs) {
        // Uses String instead of Path for baseName, because patchDir's FileSystem may not match
        // the default FileSystem from Paths.get().
        String baseName = Paths.get(patch.path()).getFileName().toString();
        Path patchFile = patchDir.resolve(baseName);
