（1）同步标记任务失败

//标记失败任务
module.exports = grunt => {
    grunt.registerTask(‘bad‘,()=>{
        console.log(‘bad working~‘);
        return false;
    });
    grunt.registerTask(‘foo‘,()=>{
        console.log(‘foo task~‘);
    })
    grunt.registerTask(‘bar‘,()=>{
        console.log(‘bar task~‘);
    })
    grunt.registerTask(‘default‘,[‘foo‘,‘bad‘,‘bar‘])
}

执行命令，yarn grunt

运行结果如下，当执行到bad任务时，报错，接下来的bar任务不再继续执行。

yarn run v1.22.10
$ C:\studyDemo\grunt-sample\node_modules\.bin\grunt
Running "foo" task
foo task~

Running "bad" task
bad working~
Warning: Task "bad" failed. Use --force to continue.

Aborted due to warnings.
error Command failed with exit code 3.

如果想要即使任务失败了，也要后续任务全部执行完，执行命令为yarn grunt --force，执行结果为下

yarn run v1.22.10
$ C:\studyDemo\grunt-sample\node_modules\.bin\grunt --force
Running "foo" task
foo task~

Running "bad" task
bad working~
Warning: Task "bad" failed. Used --force, continuing.

Running "bar" task
bar task~

Done, but with warnings.
Done in 0.95s.

（2）异步标记任务失败

// grunt的异步任务标记任务失败,需要给异步的回调函数指定一个false的实参，就可以标记为这个任务失败了
    grunt.registerTask(‘bad-async‘,function(){
        const done = this.async();
        setTimeout(()=>{
            console.log(‘bad async‘);
            done(false);
        },1000)
    })
