如何找出导致此IllegalAccessError问题的原因？任何帮助表示赞赏.

我已经按照一些修复/解决方法从maven使用Gson 2.8.这是部分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>

和完整的堆栈跟踪:
