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;
}
});
