我有一个 Spring Boot 项目，它是用 Java 21 和 Gradle 8.4 编写的。我安装了 Java 21 JDK。当我在 IntelliJ IDEA 中运行它时，它抛出一个错误：
2024-04-26 02:16:43.098 ERROR 904 --- [ main] o.s.boot.SpringApplication : Application run failed

到处都建议更新 jdk 或 Gradle 版本，但我已经这样做了:(
这是我的build.gradle：
plugins {
id 'org.springframework.boot' version '3.2.5'
id "io.spring.dependency-management" version "1.1.4"
id 'java'
}
version = '1.0.2'
group = 'org.gradle.samples'
java {
sourceCompatibility = JavaVersion.VERSION_21
}
repositories {
mavenCentral()
}
dependencies {
implementation platform('org.springframework.boot:spring-boot-dependencies:3.2.5')
implementation ('org.casbin:jcasbin:1.55.0') {
exclude module: "logback-classic"
}
implementation ('org.casbin:redis-adapter:1.0.0') {
exclude module: "logback-classic"
}
implementation 'org.springframework.boot:spring-boot-starter:3.2.5'
implementation 'io.github.lognet:grpc-spring-boot-starter:5.1.5'
implementation 'com.google.code.gson:gson:2.10.1'
implementation 'org.flywaydb:flyway-core'
implementation 'org.springframework.boot:spring-boot-starter-security'
implementation 'org.postgresql:postgresql'

runtimeOnly 'org.postgresql:postgresql'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.security:spring-security-test'
testRuntimeOnly 'org.junit.platform:junit-platform-launcher'
}
//dependencyManagement {
// imports {
// mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
// }
//}
tasks.named('test', Test) {
useJUnitPlatform()
}
我还尝试将项目迁移到 Java 17 或使用它 - https://stackoverflow.com/a/64863465/287647 没有帮助:(
这是怎么回事？我该如何解决？
看来这是Java编译错误。尝试使用当前的 Java 版本重新编译该类，或者降级到用于编译第一个实例中的代码的 java 版本。
