如何找出造成IllegalAccessError問題的原因？任何幫助表示讚賞。com.google.gson.Gson.newJsonWriter上的改進2引起的java.lang.IllegalAccessError問題
我已經遵循了一些修復/解決方法，並從maven使用Gson 2.8。下面是部分Maven配置：
<dependency>
<groupId>com.squareup.retrofit2</groupId>
<artifactId>converter-gson</artifactId>
<version>2.2.0</version>
<exclusions>
<exclusion>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.0</version>
</dependency>
和完整的堆棧跟蹤：

您似乎有錯誤的依賴關係。 'GsonRequestBodyConverter.java：45'適用於我，如果我至少從一個「vanilla」Java程序運行它（並且沒有反射的東西，所以可能存在二進制不兼容）。順便說一下，你會考慮遷移到[Spring REST模板]（https://spring.io/guides/gs/consuming-rest/）嗎？這更符合Spring框架。還是你選擇Retrofit拒絕那個Spring組件？ –
@LyubomyrShaydariv感謝您的回覆。 Retrofit不是我的選擇，它被第三方軟件包使用：plaid-java，我們使用它。是的，我知道這個問題可能在一些依賴衝突中，但是由於該項目使用了許多第三方庫，您是否知道找出哪一個會導致問題？ – Billhatsv
@LyubomyrShaydariv也感謝格式化。 – Billhatsv
