How can I make a Grunt task fail if one of its sub

问题:

I have a build task in grunt, which looks like this:

grunt.registerTask("build", ["jshint", "uglify"]);

The problem is that the uglify task runs even if the jshint task fails, how can I make the 'build' task terminate if one of it's sub tasks fails?

回答1:

The default behavior in Grunt is to not run subsequent tasks if one fails. So you must be using the force option somewhere. You are either:

1 - passing --force on the command line

2 - calling grunt.option( 'force', true ); somewhere

3 - have the jshint force option set on your jshint task

Note that in the case of calling grunt.option( 'force', true );, it remains true for the remainder of the batch, not just inside the task where it was set. see this question and this question for details.
