Error: targetMethod error::java.lang.NoClassDefFoundError: Failed resolution of: L

封装安卓UTS库时，遇到如下问题：

Error: targetMethod error::java.lang.NoClassDefFoundError: Failed resolution of: Lcom/ccb/ccbnetpay/platform/CcbPayPlatform$Builder;

三方库如下：

import Builder from '../../../../com/ccb/ccbnetpay/platform/CcbPayPlatform/Builder';  
import Platform from '../../../../com/ccb/ccbnetpay/platform/Platform';  
export default class CcbPayPlatform extends Platform {  
    public static class: Class<CcbPayPlatform>;  
    static Builder: typeof Builder;  
    public constructor(param0: Builder);  
    public startAppOrH5(): void;  
}

调用如下：

    let builder = new CcbPayPlatform.Builder()  
            builder.setActivity(UTSAndroid.getUniActivity()! as Activity)  
            builder.setParams(response)  
            builder.setPayStyle(Platform.PayStyle.APP_OR_H5_PAY)  
            let ccbPayPlatform = builder.build()  
            ccbPayPlatform.pay()

整体应该问题出在，new CcbPayPlatform.Builder() 这行，感觉像是找不到内部类，但是要如何修改内，因为这个Builder类内部有很多个，只是包名不一样，直接重命名也不行，构造函数不对。该如何修复
