Example 1 with Command

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

the class GitRepository method executeGit.

private static CommandOutputWithStatus executeGit(Path cwd, Iterable<String> params, Map<String, String> env, boolean verbose, int maxLogLines) throws CommandException {

Example 2 with Command

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

the class GitRepository method gitAllowNonZeroExit.
