Gradle 构建中出现“Caused by: java.lang.ClassNotFoundException: org.jooq.impl.DSL”错误

问题描述 投票：0回答：1

我正在尝试运行一个使用 dcm 的 Gradle 项目 (https://github.com/vmware/declarative-cluster-management)。

我调用了“./gradlew build”，这是成功的，然后“java -jar build/libs/project.jar”来运行主类，为此我收到了此错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/jooq/impl/DSL
    at com.rebalancer.LoadBalance.setup(LoadBalance.java:92)
    at com.rebalancer.LoadBalance.<init>(LoadBalance.java:43)
    at com.rebalancer.RebalancerExperiment.main(RebalancerExperiment.java:20)
Caused by: java.lang.ClassNotFoundException: org.jooq.impl.DSL
    at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:641)
    at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188)
    at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:520)
    ... 3 more

我尝试确保正确设置了依赖项。以下是我的build.gradle：

plugins {
    id 'java'
}

jar {
    manifest {
        attributes 'Main-Class': 'com.rebalancer.RebalancerExperiment'
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'com.vmware.dcm:dcm:0.15.0'
    implementation "org.jooq:jooq:3.13.1"
    implementation "org.jooq:jooq-meta:3.13.1"
    implementation "com.google.guava:guava:${guavaVersion}"
    implementation "org.junit.jupiter:junit-jupiter:${junitJupiterVersion}"
    implementation "org.junit-pioneer:junit-pioneer:${junitPioneerVersion}"
}

DCM项目也使用jooq库，因此我通过使用“./gradlew依赖项”确保两个版本使用相同的版本（并且我避免版本冲突）。这些是运行时的依赖项：

我调用了（...）“java -jar build/libs/project.jar”

那是你的问题。您不仅必须提供自己的代码，还必须提供包含您使用的所有依赖项的类路径。这些并没有神奇地包含在内。如果您使用 Gradle 启动应用程序，则无需手动调用 

java
，它会自动为您执行此操作。
