在RunMirai上运行正常，编译成插件运行时就抛出ClassNotFoundException

用Hutool的CronUtil写了一个定时任务，CronUtil用法如下
Hutool添加全局定时任务-CronUtil
配置文件内容如下：[org.ASN70.apiExercise] #每5秒向控制台打印当前时间（测试用） getAPI.jobs.Test = */5 * * * * * *定时任务类代码如下：
class getAPI { //需要定时执行的任务 object jobs { fun Test() { val nowIs = LocalDateTimeUtil.now().format(DateTimeFormatter.ofPattern("HH-mm-ss")).toString() println(nowIs) } } }在RunMirai下运行没有任何问题，可以每5秒向控制台打印时间，但是编译成插件在Console运行时（Mirai Console 2.12.0）有如下报错

mirai-console (2.12.0)插件 的 class 不会加载在 BuiltinClassLoader ，而是每个插件有独立的 ClassLoader
比较简单的处理方法是
var oc = Thread.currentThread().getContextClassLoader(); try { Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader()); // do something } finally { Thread.currentThread().setContextClassLoader(oc); } -
@cssxsh 感谢解答，这部分代码该怎么使用呢，是要放在哪里？
-
@N70_
这段代码是用来包裹
CronUtil.schedule的你应该把
CronUtil.schedule放在// do something那里 -
@cssxsh 在PluginMain里只用到了这三个方法
CronUtil.setCronSetting("$configFolderPath\\cron.setting") CronUtil.setMatchSecond(true) CronUtil.start()我应该去CronUtil.java源文件里添加您给出的这段代码吗
-
都不知道怎么说你好
那就改成你用的这三句阿var oc = Thread.currentThread().getContextClassLoader(); try { Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader()); CronUtil.setCronSetting("$configFolderPath/cron.setting") CronUtil.setMatchSecond(true) CronUtil.start() } finally { Thread.currentThread().setContextClassLoader(oc); } -
@cssxsh 太感激您了！！已经解决问题了！！
