RE: 使用Quartz依赖不能启动Mirai发布在 BUG反馈
@cssxsh 我的机器人主程序 MiraiBot.java：

RE: 使用Quartz依赖不能启动Mirai发布在 BUG反馈
@cssxsh 这两次的报错是一样的...
此外我在debug时发现并没有执行更换类加载器的代码，不知道是不是真的只是quartz库的问题（可是我明明gradle依赖了呀💦💦） -
RE: 使用Quartz依赖不能启动Mirai发布在 BUG反馈
@cssxsh
未能解决，请问这里的类加载器的插件不是当前使用的Bot吗（我这里是MiraiBot extends JavaPlugin），使用JavaPlugin.class也能没能解决现在不清楚是解决方案的那一步出了问题
这里是报错信息2023-12-08 00:23:42 E/main: Failed to init MiraiConsole. net.mamoe.mirai.console.internal.util.ServiceLoadException: Could not load service com.mirai.MiraiBot. at net.mamoe.mirai.console.internal.util.PluginServiceHelper.loadService(PluginServiceHelper.kt:60) at net.mamoe.mirai.console.internal.util.PluginServiceHelper.loadAllServices(PluginServiceHelper.kt:42) at net.mamoe.mirai.console.internal.plugin.BuiltInJvmPluginLoaderImpl$extractPlugins$findAllInstances$2.invoke(BuiltInJvmPluginLoaderImpl.kt:170) at net.mamoe.mirai.console.internal.plugin.BuiltInJvmPluginLoaderImpl$extractPlugins$findAllInstances$2.invoke(BuiltInJvmPluginLoaderImpl.kt:165) at kotlin.sequences.TransformingSequence$iterator$1.next(Sequences.kt:210) at kotlin.sequences.FlatteningSequence$iterator$1.ensureItemIterator(Sequences.kt:314) at kotlin.sequences.FlatteningSequence$iterator$1.hasNext(Sequences.kt:303) at kotlin.sequences.TransformingSequence$iterator$1.hasNext(Sequences.kt:214) at kotlin.sequences.TransformingSequence$iterator$1.hasNext(Sequences.kt:214) at kotlin.sequences.FlatteningSequence$iterator$1.ensureItemIterator(Sequences.kt:316) at kotlin.sequences.FlatteningSequence$iterator$1.hasNext(Sequences.kt:303) at kotlin.sequences.SequencesKt___SequencesKt.toCollection(_Sequences.kt:786) at kotlin.sequences.SequencesKt___SequencesKt.toSet(_Sequences.kt:827) at net.mamoe.mirai.console.internal.plugin.BuiltInJvmPluginLoaderImpl.extractPlugins(BuiltInJvmPluginLoaderImpl.kt:191) at net.mamoe.mirai.console.internal.plugin.BuiltInJvmPluginLoaderImpl.listPlugins(BuiltInJvmPluginLoaderImpl.kt:66) at net.mamoe.mirai.console.plugin.jvm.JvmPluginLoader$BuiltIn.listPlugins(JvmPluginLoader.kt) at net.mamoe.mirai.console.internal.plugin.PluginManagerImpl.listAndSortAllPlugins(PluginManagerImpl.kt:192) at net.mamoe.mirai.console.internal.plugin.PluginManagerImpl.findAndSortAllPluginsUsingBuiltInLoaders(PluginManagerImpl.kt:138) at net.mamoe.mirai.console.internal.plugin.PluginManagerImpl.loadAllPluginsUsingBuiltInLoaders$mirai_console(PluginManagerImpl.kt:148) at net.mamoe.mirai.console.internal.MiraiConsoleImplementationBridge.doStart$mirai_console(MiraiConsoleImplementationBridge.kt:178) at net.mamoe.mirai.console.MiraiConsoleImplementation$Companion.start(MiraiConsoleImplementation.kt:464) at net.mamoe.mirai.console.terminal.MiraiConsoleTerminalLoader.startAsDaemon(MiraiConsoleTerminalLoader.kt:168) at net.mamoe.mirai.console.terminal.MiraiConsoleTerminalLoader.startAsDaemon$default(MiraiConsoleTerminalLoader.kt:167) at net.mamoe.mirai.console.terminal.MiraiConsoleTerminalLoader.main(MiraiConsoleTerminalLoader.kt:52) Caused by: java.lang.NoClassDefFoundError: org/quartz/SchedulerException at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Class.java:467) at net.mamoe.mirai.console.internal.util.PluginServiceHelper.loadService(PluginServiceHelper.kt:51) Caused by: java.lang.NoClassDefFoundError: org/quartz/SchedulerException ... 23 more Caused by: java.lang.ClassNotFoundException: org.quartz.SchedulerException at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:641) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188) Caused by: java.lang.ClassNotFoundException: org.quartz.SchedulerException at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:520) at net.mamoe.mirai.console.internal.plugin.JvmPluginClassLoaderN.loadClass(JvmPluginClassLoader.kt:389) ... 26 more -
使用Quartz依赖不能启动Mirai发布在 BUG反馈
使用了该依赖无法启动

如何用java异步只阻塞当前事件处理器发布在 开发交流
（kotlin,java多线程小白💦💦可能很多术语不太会说很抱歉
需求：异步发送两个http请求，阻塞获取两个值返回进行处理
我写了一个CompletableFuture future
问题：我在event监听器处理的时候调用future.join()和future.get()并不能阻塞event处理，导致get没有返回造成NullPointException，我想知道join会不会阻塞subcribleAlways(...)和单个event处理线程
这个在kotlin里面叫做协程吧，类似这样的需求在java里面怎么实现

@2623277496 addImageElement(Image, Width, Height, Zoom)这个方法也可以

RE: image-combiner 一个快捷制图的库发布在 技术交流板块
如果JDK8以上出现create()报错的，是因为没有sun包，需要改一下jvm参数，具体参考这个帖子

image-combiner 一个快捷制图的库发布在 技术交流板块
https://gitee.com/dromara/image-combiner
不是我做的，以下从README复制的
1.1 项目背景
最近公司上了不少传播方面的需求，免不了合成各种营销图片，图片合成本身并不是什么高深的技术，但用底层api去搞确实繁琐，于是抽时间封装了一个小工具，初衷是解放生产力，后来发现挺好使，那就开源吧，花了一个整天重新整理了一下代码，作为自己从业十年第一个开源项目（打破零记录，哈哈），希望能够帮助到需要的小伙伴~1.2 ImageCombiner能够做什么?
ImageCombiner是一个专门用于Java服务端图片合成的工具，没有很复杂的功能，简单实用，从实际业务场景出发，提供简单的接口，几行代码即可实现图片拼合（当然用于合成水印也可以），素材上支持图片、文本、矩形三种，支持定位、缩放、旋转、圆角、透明度、颜色、字体、字号、删除线、居中绘制、文本自动换行等特性，足够覆盖图片合成的日常需求。1.3 先看一下效果
基本功能展示（更多效果可自行探索）
avater专门开了一个作品搜集&展示的issue，可以秀一秀成果，顺带分享下思路~
为什么build了还是不通过呢
