java maven测试命令给出错误

Question

当我尝试执行mvn test命令时，这些错误正在发生 。我不知道该怎么办。

var konamicode = [38,38,40,40,37,39,37,39,66,65];
var kc=0; 

function checker() {
   if (kc==10) {
    // What you want to occur when code matches goes in here. 

    kc=0;  // This resets the sequence. 
    alert("It Worked!");
   }
}

function keyUp(e) {
   var keynum;
     if (window.event) { keynum = event.keyCode; }
       else if (e.which) { keynum = e.which; }
        for (i = 0; i < 222; i++) { // The 222 represents all the keys on the keyboard.

    var kx=konamicode[kc]; // kx represents the current position in the code sequence.
    if (keynum == i) {
        // Checks to see if key matches sequence,  and resets sequence if it doesn't.
        if (i!=kx){kc=0;} else {kc++;}
    }
  }
 checker();
}
