我已经检查了其他线程是否存在此问题，但他们的情况和解决方案不适用于我的情况。
该程序应该在蓝牙设备和计算机之间创建连接，并且应该从所述设备接收数据。
因此，我使用蓝牙连接所需的库，它们本身包含清单文件。我猜测，这就是问题发生的地方。
我已经尝试过使用不同的 JDK 但没有成功。
这是完整的错误消息：

I have checked the other threads with this problem but their situations and solutions do not apply in my case.
The program should create a connection between a bluetooth device and the computer, and is supposed to receive data from said device.
Therefore I am using libraries needed for the bluetooth connection that themselves contain manifest files. This, I am guessing, is where the problem is occurring.
I have already tried using different JDKs but with no success.
Here is the entire error message:

尝试从 jar 中删除 META-INF 文件夹，添加清单并再次签署 JAR，它对我有帮助： http://jehy.ru/articles/2013/12/13/invalid-signature-file-digest-for-manifest-main-attributes/
Try removing META-INF folder from jar, adding manifest and signing JAR again, it helped me: http://jehy.ru/articles/2013/12/13/invalid-signature-file-digest-for-manifest-main-attributes/
