Gson 在 Java 9+ 模块化系统下无法反射访问 java.io.File#path 私有字段，导致包含 File 或 ApacheHttpClientBuilder 字段的配置类序列化失败。

Failed making field 'java.io.File#path' accessible; 
either increase its visibility or write a custom TypeAdapter for its declaring type.

修改内容

参照 WxMpGsonBuilder 已有的修复方案，为其他模块的 GsonBuilder 添加 ExclusionStrategy：

• WxMaGsonBuilder (miniapp)
• WxCpGsonBuilder (cp)
• WxOpenGsonBuilder (open)
• WxQidianGsonBuilder (qidian)
• WxGsonBuilder (common)

INSTANCE.setExclusionStrategies(new ExclusionStrategy() {
  @Override
  public boolean shouldSkipField(FieldAttributes fieldAttributes) {
    return false;
  }

  @Override
  public boolean shouldSkipClass(Class<?> aClass) {
    return aClass == File.class || aClass == ApacheHttpClientBuilder.class;
  }
});
