Answer 1

听起来像缺少的jar，请检查您的依赖项是否在类路径中

Answer 2

Clean and build before run. That may solve the issue since you already add required jars.make sure that those jar visible to the project, and other words add those jar to class path.

Answer 3

I know it's an old question but I had this same problem and there are no much references for this particular exception (actually I think is always this same question with the same answers). I was working with a sample code for MassPay ( https://github.com/paypal/codesamples-java/blob/master/src/main/java/com/sample/merchant/MassPay.java ) and got:

java.lang.NoSuchMethodError: com.paypal.core.BaseService.<init>(Ljava/io/InputStream;)V
    at urn.ebay.api.PayPalAPI.PayPalAPIInterfaceServiceService.<init>(PayPalAPIInterfaceServiceService.java:190)
    at urn.ebay.api.PayPalAPI.PayPalAPIInterfaceServiceService.<init>(PayPalAPIInterfaceServiceService.java:175)
    at urn.ebay.api.PayPalAPI.PayPalAPIInterfaceServiceService.<init>(PayPalAPIInterfaceServiceService.java:160)

In my case, I've solved the problem by modifying the merchantsdk's version, the latest version now is the 2.13.117 but I had changed it to 2.2.98 .
Hope it helps someone else.
