I have created a EurekaServer in STS but when I am trying to run it as a SpringBootApplication it is giving UnsupportedClassVersionError

Here is the pom.xml

4.0.0 org.springframework.boot spring-boot-starter-parent 3.0.0 com.vipul EurekaServer 0.0.1-SNAPSHOT EurekaServer Eureka Server <java.version>17</java.version> <spring-cloud.version>2022.0.0-RC2</spring-cloud.version> org.springframework.cloud spring-cloud-starter-netflix-eureka-server

I am getting this error when running EurekaServerApplication

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/springframework/boot/SpringApplication has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 60.0 at java.base/java.lang.ClassLoader.defineClass1(Native Method) at java.base/java.lang.ClassLoader.defineClass(ClassLoader.java:1010) at java.base/java.security.SecureClassLoader.defineClass(SecureClassLoader.java:150) at java.base/jdk.internal.loader.BuiltinClassLoader.defineClass(BuiltinClassLoader.java:855) at java.base/jdk.internal.loader.BuiltinClassLoader.findClassOnClassPathOrNull(BuiltinClassLoader.java:753) at java.base/jdk.internal.loader.BuiltinClassLoader.loadClassOrNull(BuiltinClassLoader.java:676) at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:634) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:182) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:519) at com.vipul.EurekaServerApplication.main(EurekaServerApplication.java:12)

It looks like you are using Spring Boot 3, which requires a JDK17 to run (https://spring.io/blog/2022/11/24/spring-boot-3-0-goes-ga). Please configure your project and your launch config to use Java 17.
