Maven编译器插件不支持类文件主要版本60

Question

我正在更新一个Spigot（Minecraft）插件，最新版本的Spigot需要Java16。在我的pom中，我将maven编译器插件目标更改为16，源代码仍然是1.8。现在我得到以下错误：

Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.2.4:shade (default) on project Plugin: Error creating shaded jar: Problem shading JAR C:\Users\Trent\workspace\Stocks\Plugin\target\Plugin-1.0-SNAPSHOT.jar entry com/tchristofferson/stocks/commands/StockbrokerCommand.class: java.lang.IllegalArgumentException: Unsupported class file major version 60

Answer 1

@wemu是正确的，maven shade插件还不支持Java16。为了解决这个问题，我不得不使用maven shade插件的快照版本(3.3.0-snapshot)，因为3.2.4还不支持Java16。
