如何使Kotlin Allopen插件与STS/Maven一起使用

Question

我配置了使用JDK 1.8的所有内容，但我的应用程序仍然无法启动。编辑器错误：无法内联用JVM Target 1.8构建的字节字节码，该字节码使用JVM Target 1.6构建。请指定正确的" -jvm-target"选项执行错误：org.springframework.beans.factory.parsing.beandefinitionparsingexception：配置问题：@configuration类" DemoApplication"可能不是最终的。删除最终修饰符继续。

我的pom：

Answer 1

不能内联用JVM Target 1.8构建的字节码为使用JVM Target 1.6构建的字节码。请指定正确的'-jvm-target'选项

是Eclipse Kotlin插件中引入的一个问题0.8.15.v20190619-1212，请参见https://youtrack.jetbrains.com/issue/ke-336。

使用0.8.16.V20190703-1421的版本解决。我不得不重新登陆我的gradle项目。
