 | 1 joyoyao 157 天前 jdk 版本改低点 |
 | 2 w568w 157 天前 这不是说得很清楚了，你运行 Gradle 的 Java 版本和 Gradle 支持的版本不匹配 |
| 4 w568w 17 天前 @yiyiniu 就按照上面日志的 Flutter fix 里写的操作啊。先看看你的 Gradle 是什么版本，然后对照 Compatibility Matrix 看看需要什么 Java 版本。Java 21 只有 Gradle 8.4 以后才支持，要么升级 Gradle ，要么降级 Java |
 | 5 guoxiaowen 157 天前 装个低版本的 jdk |
 | 7 lemos1235 157 天前 升级 gradle ，修改 android/gradle/wrapper/gradle-wrapper.properties 。 或者用旧的 flutter 版本 |
 | 8 gavinhome 157 天前 一般都是版本不匹配问题导致的 |
