Intellij Maven java.lang.IllegalArgumentException: Unsupported class 文件主要版本 61 并且 Entity 使用不支持的 JDK 编译

Question

我正在尝试使用数据库开发应用程序，但遇到了很多错误，例如java.lang.IllegalArgumentException: Unsupported class 文件主要版本 61和[EL Severe]: metadata: 2022-01-26 17:43: (422250493)--使用不受支持的 JDK 编译 database.model.StageEntity class。 将此错误报告给 EclipseLink 开源项目。 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，但我一般不熟悉 intellij 或 Java，希望我会有人可以为我的问题找到答案。 这是我的持久性。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.StageTeamEntity</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.driver" value="org.postgresql.Driver"/>
        <property name="eclipselink.jdbc.user" value="postgres"/>
        <property name="eclipselink.jdbc.password" value="root"/>
    </properties>
</persistence-unit>

这是我的 pom.xml 文件

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.example</groupId> <artifactId>MIP1</artifactId> <version>1.0-SNAPSHOT</version> <properties> <maven.compiler.source>17.0.2</maven.compiler.source> <maven.compiler.target>17.0.2</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>org.openjfx</groupId> <artifactId>javafx-controls</artifactId> <version>17.0.1</version> </dependency> <dependency> <groupId>org.openjfx</groupId> <artifactId>javafx-fxml</artifactId> <version>17.0.1</version> </dependency> <dependency> <groupId>org.eclipse.persistence</groupId> <artifactId>eclipselink</artifactId> <version>2.7.7</version> </dependency> <dependency> <groupId>org.eclipse.persistence</groupId> <artifactId>javax.persistence</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> <version>42.2.2</version> </dependency>

这是我所有的警告和错误

您提到的问题也可能是由于使用了执行某种代码检查/生成的库，并且还没有准备好使用这个非常年轻的 class 文件版本。 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 go 回到 Java 16 并完全清理并重建您的项目。

例如，请参阅此说明：更新 ECLIPSELINK 以支持 JAVA 17 的 ASM 9.1
