写阿里服务识别车牌号功能遇到的bug【包含使用阿里服务识别车牌号功能代码】

Exception in thread "main" java.lang.NoSuchMethodError: com.aliyun.credentials.Client.getCredential()Lcom/aliyun/credentials/models/CredentialModel;
	at com.aliyun.teaopenapi.Client.doRequest(Client.java:812)
	at com.aliyun.teaopenapi.Client.callApi(Client.java:1080)
	at com.aliyun.openplatform20191219.Client.authorizeFileUploadWithOptions(Client.java:46)
	at com.aliyun.ocr20191230.Client.recognizeLicensePlateAdvance(Client.java:770)
	at com.utils.RecognizeLicensePlateAli.main(RecognizeLicensePlateAli.java:59)

其实解决bug很简单，是缺了个包，而且这个是运行时异常
