當我嘗試在失敗與下面的跟蹤Netbeans的Maven項目運行文件：的Maven無法運行該文件（LifecycleExecutionException）

我在代碼中沒有誤差修改編譯或警告。
主要方法：
public static void main(String[] args) {
boolean[] df = Utils.toBinary(17, 5);
boolean[] ca = Utils.toBinary(3, 3);
boolean[] icao = Utils.toBinary(0x1ab8, 24);
boolean[] result = Utils.concatArrays(df, ca, icao); // *
byte[] frame = Utils.booleansToBytes(result); // *
System.out.println(Utils.bytesToString(frame));
}
當我註釋掉與*運行細紋。
下面是實現這些方法：
public static byte[] booleansToBytes(boolean[] boolArr) {
if (boolArr.length % 8 != 0) {
throw new IllegalArgumentException("Boolean array size must be multiple of 8!");
}
byte[] byteArr = new byte[boolArr.length/8];
for (int i = 0; i < byteArr.length; i++) {
byteArr[i] = boolsToByte(boolArr, 8 * i);
}
return byteArr;
}
public static boolean[] concatArrays(boolean[]... arrays) {
boolean[] result = null;
int offset = 0;
for (int i = 0; i < arrays.length; i++) {
if (i == 0) {
result = Arrays.copyOf(arrays[i], arrays[i].length);
} else {
System.arraycopy(arrays[i], 0, result, offset, arrays[i].length);
}
offset += arrays[i].length;
}
return result;
}
