Java getEncoded（）NoSuchMethodError

我正在使用这个web推送java库：

Gradle构建任务，编译为在Coldfusion中使用的jar文件

jar {
  baseName = 'web-push'
  version = '3.0.0'
  doFirst {
      from {
          configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
      }
  }
  exclude 'META-INF/*.RSA', 'META-INF/*.SF','META-INF/*.DSA' 
}

因此，我有一个包含所有依赖项的正常运行的jar文件。然而，当我去发送通知时，我得到了这个错误

java.lang.NoSuchMethodError:org.bouncycastle.math.ec.ECPoint.getEncoded（Z）[B

它指向

Utils.java

public static byte[] savePublicKey(ECPublicKey publicKey) {
    return publicKey.getQ().getEncoded(false);
}

据我所知，

getEncoded

是一个build int java Key方法。因此我不确定是否因为

publicKey.getQ

不是有效的键，或者因为我需要导入/包含一个java Key类而出现此错误

提前感谢您提供的任何提示/帮助

CFML代码

<cfscript>

variables.server.pubKey = 'XXXXXXXXXXX';
variables.server.priKey = 'XXXXXX';

variables.subscription = {
      "endpoint": "https://fcm.googleapis.com/fcm/send/eEmctHWg8-k:APA91bF-kzQfUv1Y1T9C3sJ3eN5zDDtyRhcDU0MyVS1XWgPIko2X7VpjeymhqDAzb-4nbg4x2SmObHk1JSITG4lmsx-40E_uNi4a_TnFavs4ICMzbeHQJzKgnuTAcQxSXDxJSBNFrzY_"

        , "auth": "zDH8z4GPHvW2zFXG0bf2pQ=="
    } 
}
variables.json = serializeJSON(variables.subscription);

variables.java.gson = createObject('java', 'com.google.gson.Gson', expandPath('/fw/jar/gson-2.8.0.jar'));

variables.lib               = expandPath('/fw/jar/web-push-3.0.0.jar');
variables.java.subscription = createObject('java', 'nl.martijndwars.webpush.Subscription', variables.lib);
variables.java.notification = createObject('java', 'nl.martijndwars.webpush.Notification', variables.lib);
variables.java.pushservice  = createObject('java', 'nl.martijndwars.webpush.PushService', variables.lib);

variables.java.subscription = variables.java.gson.fromJson(variables.json, variables.java.subscription.class);

variables.java.notification.init(variables.java.subscription, 'Hello, World!');

variables.java.pushservice.init(variables.server.pubKey, variables.server.priKey, "mailto:craig@thinkerventures.com");

variables.resonse = variables.java.pushservice.send(variables.java.notification);

完整堆栈跟踪消息是什么，特别是“由…”部分（如果有）？另外，如何通过

加载jar。javaSettings

？可能是由一个依赖项和内置库（bouncy castle就是其中之一）之间的版本冲突引起的。添加了堆栈跟踪，但不确定这是否会有帮助，因为coldfusion正在调用jar。是的，存在

getEncoded

方法。但它不接受任何参数。我从

getEncoded

调用中删除了false参数，并重新生成jar，现在它通过了该函数。只会在更深层的问题上出错行…认为库可能正在使用不同版本的bouncyhouse？（编辑）这证实了Lucee与它自己的Bouncy Castle版本捆绑在一起。是的，从错误看来，可能是加载了该版本，而不是库所需的较新版本。变量.lib路径是否包括BC jar？我不知怎的找到了它。感谢您的回复。我的解决方案是，我使用了来自的另一个依赖项在bouncycastle中，他们有不同的groupId bouncycastle和org.bouncycastle，但使用相同的artifactId。这花了我的时间来确定。
