Question

我尝试使用@Grab将一些库添加到一个简单的groovy脚本中。但我无法通过编译步骤，因为似乎有些事情是试图解析XML而无法找到实现。

import retrofit2.Retrofit
@Grapes([
    @Grab(group = 'com.squareup.retrofit2', module = 'retrofit', version = '2.2.0'),
    @Grab(group = 'com.squareup.retrofit2', module = 'converter-jackson', version = '2.2.0'),
    @Grab(group = 'com.squareup.okhttp3', module = 'okhttp', version = '3.5.0'),
    @Grab(group = 'org.slf4j', module = 'slf4j-simple', version = '1.7.12')
])

import retrofit2.converter.gson.GsonConverterFactory

def result = new Retrofit.Builder()
    .baseUrl("http://weather.livedoor.com")
    .addConverterFactory(GsonConverterFactory.create())
    .build()
    .create(WeatherService.class)
    .find("400040")

result.execute()

println result.pinpointLocations

在编译期间导致此错误：

不知道为什么你要拉杰克逊，然后尝试使用Gson ......无论如何......这都有效

（必须编写我自己的WeatherService，因为你没有指定一个）

@Grab('com.squareup.retrofit2:retrofit:2.2.0')
@Grab('com.squareup.retrofit2:converter-gson:2.2.0')
@Grab('com.squareup.okhttp3:okhttp:3.5.0')
import retrofit2.Call
import retrofit2.Retrofit
import retrofit2.converter.gson.GsonConverterFactory
import retrofit2.http.GET
import retrofit2.http.Query
import groovy.transform.*

@ToString
class Link {
    String link
    String name
}

class ForecastResponse {
    List<Link> pinpointLocations
}

interface WeatherService {
    @GET('forecast/webservice/json/v1')
    Call<ForecastResponse> find(@Query('city') String city)
}

def result = new Retrofit.Builder()
    .baseUrl("http://weather.livedoor.com")
    .addConverterFactory(GsonConverterFactory.create())
    .build()
    .create(WeatherService.class)
    .find("400040")

result = result.execute().body()

result.pinpointLocations.each {
    println it
}

Groovy @Grab不会抱怨
