非常感谢楼主科普。目前我没有在开发界面找到群聊相关的功能，不过就算能加群，也似乎只能监听到at机器人的消息，这点实在有点尴尬，还是打算mirai不能用了再想办法。另外请问公域和私域的区别是什么？（官方文档甚至要申请通过了才能看x）

频繁出现如下错误，虽然不影响插件正常工作，但占用了日志大量空间，经观察不是来源于自建rsshub的链接都会报这个错

@cssxsh 非常抱歉，看得太不仔细了，现在明白了

@cssxsh 有没有办法尽量减少轮询的时间呢

请问每次rss有新消息到bot发出消息有一定延迟是什么原因（之前以为是rsshub的原因，但禁止了rsshub的缓存之后还是有延迟）

@Karlatemp 谢谢，问题解决了

@Karlatemp 因为插件使用java写的，我觉得在kotlin环境下运行可能得到的结果不一样，所以我尝试在java中加入了以下代码

public void onEnable() {
    try {
        dump(Class.forName("org.apache.http.client.methods.HttpUriRequest"));
        dump(Majsoul.class.getClassLoader().loadClass("org.apache.http.client.methods.HttpUriRequest"));
    } catch (ClassNotFoundException e) {
        throw new RuntimeException(e);
    }
}

void dump(Class<?> c) {
    System.out.println(c);
    System.out.println("|- CCL " + c.getClassLoader());
}

得到的结果是

2022-11-17 10:48:42 I/stdout: interface org.apache.http.client.methods.HttpUriRequest
2022-11-17 10:48:42 I/stdout: |- CCL sun.misc.Launcher$AppClassLoader@55f96302

@cssxsh 版本是2.13.0-RC2

java初学者，想试着开发插件玩一下，遇到了以下问题。
在build.gradle.kts中的dependencies加入了

implementation("org.apache.httpcomponents:httpclient:4.5.13")

能顺利通过编译，但是程序每次执行到HttpClients.createDefault()方法时，就会有该报错

java.lang.LinkageError: loader constraint violation: when resolving method "org.apache.http.impl.client.CloseableHttpClient.execute(Lorg/apache/http/client/methods/HttpUriRequest;)Lorg/apache/http/client/methods/CloseableHttpResponse;" the class loader (instance of net/mamoe/mirai/console/internal/plugin/JvmPluginClassLoaderN) of the current class, com/frankcwl/Majsoul, and the class loader (instance of net/mamoe/mirai/console/internal/plugin/DynLibClassLoader) for the method's defining class, org/apache/http/impl/client/CloseableHttpClient, have different Class objects for the type org/apache/http/client/methods/HttpUriRequest used in the signature

可能是因为引入的包和mirai依赖的冲突了，但是如果不在dependencies中添加的话，编译时就会报错Cannot resolve symbol 'HttpClients'
本人之前没有接触过gradle，请问该怎么修改

收不到来自lolicon api的返回，报了以下错误（不是连不上pixiv的问题）
