今天使用bcprov-jdk15on.jar包时,报以下错误:

在网上找了各种方法,也没解决问题。主要使用了一下方法:

1. 说maven会解压包导致jar包的签名不能使用,所以放在jre/lib/ext目录下,并使用Security.addProvider(new BouncyCastleProvider())添加Provider;

2. 怀疑LICENSE.class类有问题,所以下载源码,将main()方法去除,重新打包,还是不行,将LICENSE.java去掉,重新打包,又报另一个类has unsigned entries,无法解析整个包的文件,但又不知问题在哪;

3. 在maven仓库下载时,有察觉到1.54版本下载量较多,本人之前使用的是1.55,怀着侥幸的心里,改成1.54版本,结果运行成功,没有报以上错误。
