Eclipse在运行或调试期间没有使用gradle dependencies jar

Question

我试图用Gradle项目做基本的hibernate任务。

Dependency JAR由Gradle下载并放置在项目和外部依赖项库中。

我没有得到任何编译时错误。但是，当我试图在Eclipse中运行或调试主类时，我得到的类不是ClassDefFoundError。

Exception in thread "main" java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration

plugins {
    // Apply the java-library plugin to add support for Java Library
    id 'java-library'
}

apply plugin: "eclipse"

dependencies {
    // This dependency is exported to consumers, that is to say found on their compile classpath.
    api 'org.apache.commons:commons-math3:3.6.1'

    // This dependency is used internally, and not exposed to consumers on their own compile classpath.
    implementation 'com.google.guava:guava:23.0'

    // Use JUnit test framework
    testImplementation 'junit:junit:4.12'

    // https://mvnrepository.com/artifact/org.hibernate/hibernate-core
    compile group: 'org.hibernate', name: 'hibernate-core', version: '5.3.6.Final'

    // https://mvnrepository.com/artifact/com.oracle.jdbc/ojdbc6
    runtime group: 'com.oracle.jdbc', name: 'ojdbc6', version: '11.1.0.6.0'

    // https://mvnrepository.com/artifact/com.oracle/ojdbc6
    runtime group: 'com.oracle', name: 'ojdbc6', version: '11.2.0.4.0-atlassian-hosted'




}

// In this section you declare where to find the dependencies of your project
repositories {
    // Use jcenter for resolving your dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
    mavenCentral()
}

提前感谢！！！

我认为您应该用构建文件中的最新更改更新类路径。Eclipse并不是在所有版本中都自动做到这一点。转到package explorer，右键单击build.gradle文件，然后从上下文菜单中选择gradle->Refresh gradle Project。

您还可以从首选项菜单中启用自动同步，转到分级，并选中“自动项目同步”复选框。
