java.lang.NoClassDefFoundError:无法初始化类 org.codehaus.groovy.vmplugin.v7.Java7 [英] java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.groovy.vmplugin.v7.Java7

问题描述

我收到此异常 java.lang.NoClassDefFoundError:无法初始化类 org.codehaus.groovy.vmplugin.v7.Java7 和 java.lang.NoClassDefFoundError:无法初始化类 org.codehaus.groovy.reflection.ReflectionCache) 当我运行 Spring Boot 应用程序时

我正在使用以下工具

STS 3.9.10 发布
打开 JDK 14 64 位
Spring Boot 2.2.5

它在 oracle jdk 上运行良好，但在 openjdk 上运行失败.我没有使用任何常规库.这是基于 maven 的 Spring Boot 项目.

解决方案

你如何运行应用程序?这可能是因为您使用 Gradle 作为构建系统和 JDK14，并且 Gradle 版本较旧.参考:https://github.com/gradle/gradle/issues/10248>

如果您使用 Gradle Wrapper，请参考 $PROJECT_ROOT/gradle/wrapper/gradle-wrapper.properties.属性 distributionUrl 应该是:distributionUrl=https://services.gradle.org/distributions/gradle-6.3-bin.zip

如果是旧版本，则更改它，运行 ./gradlew clean build 并重试.

I am getting this exception java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.groovy.vmplugin.v7.Java7 and java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.groovy.reflection.ReflectionCache) when i run the spring boot application

I am using below tools

STS 3.9.10 release
Open JDK 14 64 bit
Spring boot 2.2.5

It worked fine with oracle jdk but its failing to run with openjdk. I am not using any groovy libs. This is maven based spring boot project.

解决方案

How do you run the application? It's probably because you use Gradle as the build system and JDK14 and the Gradle version is old. Reference: https://github.com/gradle/gradle/issues/10248

If you use Gradle Wrapper then refer to $PROJECT_ROOT/gradle/wrapper/gradle-wrapper.properties. Property distributionUrl should be: distributionUrl=https://services.gradle.org/distributions/gradle-6.3-bin.zip

If it's an older version then change it, run ./gradlew clean build and try again.
