Intellij Maven java.lang.IllegalArgumentException: 不受支持的 class 文件主要版本 61 和实体是使用不受支持的 JDK 编译的

Question

我正在尝试开发一个带有数据库的应用程序，但我遇到了很多错误，比如 java.lang.IllegalArgumentException：不支持 class 文件主要版本 61 和 [EL 严重]：元数据：2022-01-26 17:43:20。 982--ServerSession(422250493)--database.model.StageEntity class 是使用不受支持的 JDK 编译的。向 EclipseLink 开源项目报告此错误。 对于通过映射创建的每个实体。这是一个 Maven 项目，所以我没有找到任何关于它的信息，只有 gradle。我在 java 17(17.0.2) 上工作，我不熟悉 intellij 或 Java 一般情况下，希望有人能为我的问题找到答案。这是我的 persistence.xml 文件

<?xml version="1.0" encoding="UTF-8"?>

<persistence-unit name="PersistenceMIP">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

    <class>database.model.StageEntity</class>

    <class>database.model.TeamEntity</class>
    <class>database.model.UserEntity</class>
    <properties>
        <property name="eclipselink.jdbc.url" value="jdbc:postgresql://localhost:5432/MIP"/>

        <property name="eclipselink.jdbc.password" value="root"/>
    </properties>

您提到的问题也可能是由于使用了执行某种代码 inspection/generation 并且尚未准备好使用这个非常年轻的 class 文件版本的库。可能 eclipselink 是这里的问题。尝试升级到最新版本，如果这没有帮助，请返回 Java 16 并完全清理并重建您的项目。

例如，请参阅此注释：UPDATE ECLIPSELINK TO SUPPORT ASM 9.1 FOR JAVA 17
