java - NoSuchMethodError 使用 maven

Question

当我运行我的 jar 时，它会引发异常。我反编译了jar，发现方法存在。我尝试在我自己的 pom 中添加 Gson 和改造依赖项，但没有成功。我错过了什么？

java.lang.NoSuchMethodError: com.google.gson.Gson.newJsonReader(Ljava/io/Reader;)Lcom/google/gson/stream/JsonReader;
    at retrofit2.converter.gson.GsonResponseBodyConverter.convert(GsonResponseBodyConverter.java:38) ~[?:?]
    at retrofit2.converter.gson.GsonResponseBodyConverter.convert(GsonResponseBodyConverter.java:27) ~[?:?]
    at retrofit2.OkHttpCall.parseResponse(OkHttpCall.java:243) ~[?:?]
    at retrofit2.OkHttpCall.execute(OkHttpCall.java:204) ~[?:?]
    at com.jaredsburrows.retrofit2.adapter.synchronous.SynchronousBodyCallAdapter.adapt(SynchronousBodyCallAdapter.java:27) ~[?:?]

我已经阅读了无数关于相同/相似问题的线程，但没有一个有助于解决这个问题。这是我现在的pom：
